DESCRIPTION

9       HylaFAX  uses  a  configuration file for the central queueing agent and
10       for each facsimile modem attached to a machine.   These  files  contain
11       information about the modems and about how the HylaFAX server processes
12       that service these modem should operate.  Configuration files  are  lo‐
13       cated in the etc subdirectory.  The configuration file for the faxq(8C)
14       program is named config.  The per-modem configuration files used by the
15       faxgetty(8C),  faxsend(8C), and pagesend(8C) programs have names of the
16       form config.devid, where devid is an identifier derived from  the  name
17       of  the  modem's device file; for example ttym2 for /dev/ttym2, term_10
18       for /dev/term/10.
19
20       Configuration files have a simple format and  are  entirely  ASCII.   A
21       configuration parameter is of the form
22            tag: value
23       where a tag identifies a parameter and a value is either a string, num‐
24       ber, or boolean value.  Comments are introduced by the ``#''  character
25       and  extend  to  the end of the line.  String values start at the first
26       non-blank character after the ``:'' and  continue  to  the  first  non-
27       whitespace  character  or,  if whitespace is to be included, may be en‐
28       closed in quote marks (``"'').  String values enclosed in  quote  marks
29       may  also use the standard C programming conventions for specifying es‐
30       cape codes; e.g. ``\n'' for a newline character and ``\xxx'' for an oc‐
31       tal value.  Numeric values are specified according to the C programming
32       conventions (leading ``0x'' for hex, leading ``0'' for octal, otherwise
33       decimal),  except  for  a  few  parameters, such as RecvFileMode, whose
34       value is interpreted strictly as an octal number and  PageChopThreshold
35       whose  value is interpreted strictly as a floating point number.  Bool‐
36       ean values are case insensitive.  For a true value, either  ``Yes''  or
37       ``On'' should be used.  For a false value, use ``No'' or ``Off''.
38
39       The  following  table  itemizes the tags and the expected type of their
40       value.  The first part lists items specific to the  operation  of  each
41       server, while the second part has items related to the servicing of the
42       modem.  Parameters marked with a ¹ are used only by the HylaFAX  sched‐
43       uler  process and should appear only in the file named config.  Parame‐
44       ters marked with a ² are used by both the scheduler and the  per-device
45       applications  and  so  should  appear  in all appropriate configuration
46       files (i.e.  config and any per-device files that make sense).  Parame‐
47       ters  not  otherwise marked should appear only in per-device configura‐
48       tion files.  More detailed information about each item is given follow‐
49       ing the table.

SERVER-ORIENTED CONFIGURATION PARAMETERS

383       These  configuration parameters affect the general operation of the fax
384       server.
385
386       AdaptiveAnswer
387              Control whether or not an adaptive answering  strategy  is  used
388              whereby  an incoming call is answered in multiple ways according
389              to the list specified in the AnswerRotary parameter.  For  exam‐
390              ple, if adaptive answering is enabled and AnswerRotary specifies
391              ``fax data'', then an incoming call will first  be  answered  as
392              fax using ModemAnswerFaxCmd and then, if that fails, as data us‐
393              ing ModemAnswerDataCmd.  If the adaptive answer strategy is  not
394              enabled,  then calls are answered using the appropriate ModemAn‐
395              swer*Cmd parameter (normally ModemAnswerCmd for unattended oper‐
396              ation).   Note that the adaptive answer strategy depends on many
397              factors that limit its  usefulness.   When  calls  are  answered
398              first  as  fax, it typically only works with a Class 1 modem be‐
399              cause it is important that the sequence of operations related to
400              answering as fax be completed in a short enough time that a sub‐
401              sequent answer for data be done before the caller times out  and
402              hangs  up  the  telephone  (for this reason Class1RecvIdentTimer
403              should be set to a  value  that  is  shorter  than  FaxT1Timer.)
404              Also,  note  that  it is sometimes necessary to arrange that the
405              phone be placed on-hook between  successive  answers;  this  can
406              typically  be  done  by inserting the appropriate command at the
407              start of the second and subsequent ModemAnswer*Cmds.
408
409       AdminGroup
410              Tells PAM what user group  is  allowed  to  administer  the  fax
411              server.  Only useful if the server is compiled with PAM enabled.
412
413       AllowIgnoreModemBusy¹
414              Whether or not to honor job requests to ignore modem busy status
415              when allocating jobs to a modem.  The intended use for this fea‐
416              ture  is to allow configurations whereby a DynamicConfig program
417              can send a fax to an incoming caller (contrary to T.30  protocol
418              for sending or polling).
419
420       AnswerRotary
421              The  sequence of answering techniques the server should ``rotate
422              through'' when answer incoming calls.  Answering techniques are:
423              Name    Description
424              fax     answer a fax call
425              data    answer a data call
426              voice   answer a voice call
427              extern  use the vgetty application to answer a call
428              any     answer a call of any/unknown type
429              When a call is not answered successfully,  the  server  advances
430              the  rotary to the next specified answering technique.  If Adap‐
431              tiveAnswer is enabled, the server will  try  all  the  answering
432              techniques for each incoming call.  Otherwise, the rotary is ad‐
433              vanced between unsuccessful phone calls.  For example, if  Adap‐
434              tiveAnswer  is  disabled  and AnswerRotary is ``fax data'', then
435              the calls will initially be answered as fax until the first call
436              is received that does not appear to be from a fax machine; after
437              that calls will be answered as if they were from  a  data  modem
438              until  the  next  unsuccessful  call;  after which they will one
439              again be answered as  fax.   Only  the  first  three  techniques
440              listed  are  used;  any  additional ones are (silently) ignored.
441              See also AnswerBias.
442
443       AnswerBias
444              The index into the AnswerRotary list that the server should  ro‐
445              tate  the  list  to  after  each successful incoming phone call.
446              List indices are numbered starting at zero.  For example, if An‐
447              swerRotary  is ``fax data'' and AnswerBias is 1, then after each
448              successful inbound call, the next call will be answered as data.
449
450       AreaCode²
451              The local area code in which the facsimile modem resides.   This
452              value  is passed to the dial string rules that are used, for ex‐
453              ample, to formulate canonical phone numbers for dialing (see Di‐
454              alStringRules below.)
455
456       AuditHook¹
457              Specifies  a program command and an interest specification indi‐
458              cating which events as described in faxwatch(8C) should  trigger
459              the execution of the program.  For example, this configuration:
460
461                  AuditHook: "bin/hook: J*S*M*R*"
462
463              would cause bin/hook to be executed upon every event.  The argu‐
464              ments passed to  the  hook  program  are  respectively  <class>,
465              <mask>, <id>, and optionally [info] where...
466
467                  <class> = JOB | SEND | MODEM | RECV
468                  <mask>  = the specific event
469                  <id>    = id of the job/modem with which the event is associated
470                  [info]  = additional information
471
472
473       BadPageHandlingMethod
474              (Class 1/1.0 only) Specifies how to react to a bad page received
475              from the remote sender:  one  of  ``RTN'',  ``DCN'',  or  ``RTN-
476              SAVE''.
477
478              If  a page is received in non-ECM mode with unacceptable quality
479              according to PercentGoodLines or MaxConseutiveBadLines  then  it
480              can  be  somewhat difficult to inform the sender of the problem.
481              Historically, HylaFAX has assumed that  signalling  RTN  to  the
482              sender  will  accomplish  this.  However, some senders are inca‐
483              pable of retransmitting pages, and to reduce burden  they  treat
484              an  RTN signal as a receipt confirmation and proceed to the next
485              page without notifying the sending user of the potential problem
486              in  readability on the receive-end.  (The assumption there being
487              that the receiving user will notify the sending  user  if  there
488              actually is a readability problem.)
489
490              A  setting  of ``RTN'' is the historic behavior and assumes that
491              an RTN signal will be enough to get the sender to retransmit  or
492              be  otherwise informed of a potential readability problem on the
493              receive-end.  The previously-received page data is marked to  be
494              overwritten by the next page data received from the sender.
495
496              A  setting  of ``DCN'' tells HylaFAX to transmit a DCN signal in
497              response to the post-page message  and  should  trigger  a  call
498              abortion  by the sender.  This should clearly indicate a problem
499              in page readability to the sender, although the receipt  of  any
500              following pages in a later call cannot be guaranteed.
501
502              A setting of ``RTN-SAVE'' more closely approximates the behavior
503              of other fax receivers (especially fax machines).  It causes Hy‐
504              laFAX  to  send  the  RTN signal but it saves the previously re‐
505              ceived page data and places the next transmitted  page  data  in
506              another page.  This is the default setting.  However, this could
507              result in multiple copies of the same page image being saved  in
508              the  same  file - if the sender does indeed retransmit the unac‐
509              ceptable pages during the same call.

512              When sending or receiving multiple documents (denoted  by  EOM),
513              this  value determines if the session logs span the entire batch
514              or, if set to no, only contain a single document.
515
516       CallIDPattern
517              A string that identifies the caller's identity in any call iden‐
518              tification  messages provided by the modem (such as Caller*ID or
519              DNIS/DID).  The specified string is compared against any  unrec‐
520              ognized  status messages received from the modem before ModemAn‐
521              swerCmd is sent to the modem.  If there is a match, then the re‐
522              mainder  of  the  message  is returned as CallIDn where n corre‐
523              sponds to the n'th instance that this CallIDPattern is from  the
524              top in the modem configuration file.  For example, for the ZyXEL
525              U-1496 this parameter would be set to
526              CallIDPattern: ``CALLER NAME: '' (note the trailing space).
527              If more than one message matches  between  instances  of  "RING"
528              messages, then the message remainders are concatenated.
529
530              The  special CallID value of "SHIELDED_DTMF" is used in conjunc‐
531              tion with ModemRingResponse and CallIDAnswerLength.  After  exe‐
532              cuting ModemRingResponse, HylaFAX will expect DTMF data (usually
533              DLE-shielded) for CallIDn until CallIDAnswerLength  is  reached.
534              Note  that if the modem is in voice mode to hear these DTMF dig‐
535              its, then it must be returned to fax mode in the ModemAnswerCmd.
536              In order to prevent this feature from losing incoming fax calls,
537              if fax sender CNG is detected while waiting for DTMF or  if  ten
538              seconds  elapse  without  sufficient DTMF then the remaining ex‐
539              pected digits will be populated by  whitespace,  triggering  fax
540              answering.
541
542              For  example, the following settings will cause HylaFAX to enter
543              voice mode and go off-hook when a RING  is  detected.   It  will
544              then  expect four DTMF digits (presumably for routing), and then
545              it will pause for 100 ms before returning to fax  mode  and  an‐
546              swering the call.
547
548                ModemRingResponse:     AT+FCLASS=8;H1
549                CallIDPattern:         SHIELDED_DTMF
550                CallIDAnswerLength:    4
551                ModemAnswerCmd:        <delay:100>AT+FCLASS=1;A
552
553              For  modems  that  do  not support AT+FCLASS=8 (such as some USR
554              modems) this may be an appropriate equivalent:
555
556                ModemRingResponse:      "AT#CLS=8\nAT#VLS=4\nATA"
557                CallIDPattern:          SHIELDED_DTMF
558                CallIDAnswerLength:     4
559                ModemAnswerCmd:         "<delay:100>AT+FCLASS=1\nATA"
560
561              Multiple entries of CallIDPattern are used together in one modem
562              configuration  file  in  order  to  capture  multiple CallID re‐
563              sponses.  For example,  the  following  settings  would  capture
564              "NDID"  responses  from  the  modem as CallID1, "NMBR" responses
565              from the modem as CallID2, "NAME" responses as CallID3,  and  it
566              would  trigger  ModemAnswerCmd  whenever CallID1 or CallID2 were
567              longer than 7 or 10 characters, respectively.
568
569                CallIDPattern:         "NDID="
570                CallIDAnswerLength:    7
571                CallIDPattern:         "NMBR="
572                CallIDAnswerLength:    10
573                CallIDPattern:         "NAME="
574
575              Note that this example is only given as an example, and probably
576              would  cause  unexpected results.  Because pattern-matching ends
577              when ModemAnswerCmd is sent to the modem, if "NDID", "NMBR", and
578              "NAME"  responses  came  from  the  modem in that order, and the
579              "NDID" response was at least 7 characters  long,  then  ModemAn‐
580              swerCmd  would  be  sent  to the modem immediately following the
581              "NDID" response, and the "NMBR" and "NAME"  responses  would  be
582              ignored.   Generally  only one CallIDAnswerLength item should be
583              in a modem configuration file.
584
585              Call identification data is usually only sent once by the  telco
586              or  PBX,  and the timing of its arrival varies upon the telco or
587              PBX and the type of line.  If HylaFAX is  configured  to  answer
588              via RingsBeforeAnswer prior to the arrival of the data, then all
589              CallID values will be null.  For example, on  US  analog  lines,
590              caller-ID  data  is usually sent between RINGs 1 and 2.  In this
591              situation, RingsBeforeAnswer should be set to ``2'' or greater.
592
593       CallIDAnswerLength
594              An integer indicating the minimum number of characters in a Cal‐
595              lID  matching  the  previous  CallIDPattern  to be received when
596              ModemAnswerCmd is sent to the modem irrespective of any RingsBe‐
597              foreAnswer  value  greater than zero.  This allows the answering
598              of calls which deliver CID/DID data but not RINGs.  For example,
599              CallIDAnswerLength: ``7''
600              would cause the call to  be  answered  when  CallID2  reached  a
601              length  of seven digits.  A value of zero for CallIDAnswerLength
602              disables this feature.
603
604       CallIDDisplay
605              Whether or not to display the CallIDPattern match in  the  modem
606              status line.
607
608       CallIDLabel
609              The label to use in the presentation of any CallIDPattern match.
610              (For example, when CallIDDisplay  or  CallIDRecord  indicate  to
611              diplay or record the match.)
612
613       CallIDRecord
614              Whether or not to record the CallIDPattern match in the received
615              image file.
616
617       CallIDType
618              Identifies the type of indicator in the associated CallIDPattern
619              match.  The special type ``calling-number'' enables the faxgetty
620              process to utilize an associated entry in the info database  for
621              items  such as senderDataSent, senderDataMissed, senderConfuses‐
622              RTN, senderConfusesPIN,  senderFumblesECM,  senderHasV17Trouble,
623              and senderSkipsV29.  See hylafax-info(5F).
624
625       ClocalAsRoot
626              Control  whether operations that set the CLOCAL bit on the modem
627              device special file are done with the effective user-ID  set  to
628              the  super-user or the ``fax'' user.  By default such operations
629              are done as the fax user, except under IRIX where they are  done
630              as the super-user (because IRIX disallows manipulation of CLOCAL
631              by anyone but the super-user).
632
633       ContCoverCmd¹
634              The program to invoke to generate a continuation cover page; see
635              ContCoverPage and mkcover(8C).
636
637       ContCoverPage¹
638              A template file to use in creating continuation cover pages.  If
639              this parameter is non-null, then the server will pass the  file‐
640              name  to the command specified by ContCoverCmd to generate cover
641              pages for outbound jobs that are continued  after  protocol  er‐
642              rors.  These cover pages identify the receiver and indicate that
643              the document is a continued transmission.  If this parameter  is
644              not specified or is null, then the server will not generate con‐
645              tinuation cover pages.  The specified pathname must be  relative
646              to the top of the fax server's spooling area.
647
648       CountryCode²
649              The local country code in which the facsimile modem resides.  As
650              for AreaCode, this value is passed to the dial string rules  for
651              use  in  formulating  canonical phone numbers for dialing (among
652              other things.)
653
654       DeviceMode
655              The file protection mode that the server should set for the  mo‐
656              dem  device  file.  Note that this value is given in octal.  The
657              default value of 0600 implies that only the facsimile user (usu‐
658              ally uucp) can access the modem.  See also chmod(2).
659
660       DialStringRules²
661              The  pathname  of  the  file that holds the rules for processing
662              user-specified dial strings; c.f.  dialrules(5F).  The specified
663              pathname  must be relative to the top of the fax server's spool‐
664              ing area; e.g.  etc/dialrules.
665
666       DistinctiveRings
667              Modern distinctive ring support on  most  modems  indicates  the
668              ring   cadence   rather  than  the  older  style  of  ``RING1'',
669              ``RING2'', etc.  To  indicate  the  ring  cadence,  DRingOn  and
670              DRingOff  values  are  presented  by  the  modem to the faxgetty
671              process.   The  modem  indicates  the  entire  cadence   between
672              ``RING'' indications Like this:
673
674                RING
675                DROF=40
676                DRON=8
677                DROF=4
678                DRON=8
679                RING
680
681              The  corresponding  DistinctiveRings parameter for this ring ca‐
682              dence would be:
683
684                DistinctiveRings:  F-8-4-8
685
686              where ``F'' tells the faxgetty process that the ring cadence  is
687              for  a  facsimile  (``V'' for voice and ``D'' for data), and the
688              other values describe the ring cadence with leading  and  ending
689              DRingOff  values  ignored.  Multiple ring cadences are indicated
690              by delimiting them with commas in this fashion:
691
692                DistinctiveRings:  V-20,F-8-4-8,D-4-2-4-8
693
694
695       DRingOff
696              A string that identifies the ``off'' value  in  any  distinctive
697              ring  cadence, for example ``DROF=''.  See also DRingOn and Dis‐
698              tinctiveRings.
699
700       DRingOn
701              A string that identifies the ``on''  value  in  any  distinctive
702              ring cadence, for example ``DRON=''.  See also DRingOff and Dis‐
703              tinctiveRings.
704
705       DynamicConfig
706              The pathname of the optional program, e.g. ``etc/localid'', that
707              makes  dynamic  configuration changes, i.e., to LocalIdentifier,
708              based on device ID and  call  identification.   The  program  is
709              passed those values as the parameters ($1 = device id, $2 = Cal‐
710              lID1, $3 = CallID2, $4 = CallID3, ...), when answering an incom‐
711              ing  call.  The program can then perform local processing as de‐
712              sired to send on standard  output  the  configuration  items  to
713              change in a ``parameter:value'' format, i.e.  ``LocalIdentifier:
714              +1.800.555.1212''.  If  there  are  multiple  parameters  to  be
715              changed,  then  each item must be on its own line.  This is com‐
716              monly used to dynamically alter the local identification of sys‐
717              tems  which  use DID/DNIS, but it can also be used to allow dif‐
718              ferent modem configurations for different senders.  This program
719              can also set the RejectCall options to cause the current call to
720              be rejected instead of answered.  Note that this  file  must  be
721              marked as executable by the faxgetty process.
722
723       EGettyArgs
724              A  string that indicates whether or not the server should use an
725              an external getty application (egetty)  to  perhaps  deduce  and
726              possibly  handle  an  incoming call.  If the string value is not
727              null, then it is interpreted as a set of arguments  to  pass  to
728              egetty.   Before  supplying  the  arguments, the string is first
729              scanned for ``%''-escape sequences: any appearance of ``%l''  is
730              replaced  with  the tty name and any appearance of ``%s'' is re‐
731              placed with the serial port speed (in decimal).  Any  appearance
732              of  escaped  numbers 1 through 9 (``%1'' through ``%9'') are re‐
733              placed by the  match  to  the  corresponding  CallIDPattern,  if
734              present.   The ``%'' character can be specified with ``%%''.  If
735              the EGettyArgs parameter is not specified in  the  configuration
736              file or if the string value is null, then ``extern'' connections
737              will be rejected.  Note that in addition to the  specified  com‐
738              mand  line arguments, egetty is invoked with its standard input,
739              output, and error descriptors directed to  the  controlling  tty
740              device.
741
742              When  egetty  completes, its exit status is evaluated and is in‐
743              terpreted to indicate what, if anything, should be done with the
744              call.   An  exit  status of ``0'' indicates an unknown call type
745              and that the call should be handled as if egetty  had  not  been
746              used.   An  exit status of ``1'' indicates a data connection and
747              that the getty(8C) program should be used to handle the call  if
748              configured  (see  GettyArgs),  otherwise it will assume that the
749              call has been answered and that a data connection is established
750              and  that  it  should proceed by issuing ModemAnswerDataBeginCmd
751              (if configured) to the modem.  An exit status of ``2'' indicates
752              a  fax  connection  is established and that it should proceed by
753              issuing ModemAnswerFaxBeginCmd (if configured) to the modem.  An
754              exit  status of ``3'' indicates a voice call and that the vgetty
755              program should be used to handle the  call  if  configured  (see
756              VGettyArgs), otherwise it will assume that the call has been an‐
757              swered and that a voice connection is established  and  that  it
758              should  proceed  by issuing ModemAnswerVoiceBeginCmd (if config‐
759              ured) to the modem.  An exit status of ``4'' is considered to be
760              an  error  condition.   The session will be terminated.  An exit
761              status of ``5'' is used to indicate that egetty handled the call
762              entirely,  is not an error condition, and that the session is to
763              be considered terminated.  Exit status values of ``11'', ``12'',
764              and  ``13'' correspond to values ``1'', ``2'', and ``3'' respec‐
765              tively except that values ``11'', ``12'',  and  ``13''  indicate
766              that  the  call  has  not been answered yet with a data, fax, or
767              voice connection.  So if GettyArgs is not configured then  Mode‐
768              mAnswerDataCmd  is  first issued to the modem for an exit status
769              of ``11'', ModemAnswerFaxCmd is first issued to the modem for an
770              exit  status of ``12'', and if VGettyArgs is not configured then
771              ModemAnswerVoiceCmd is first issued to the  modem  for  an  exit
772              status of ``13''.
773
774       FAXNumber
775              The  phone  number  associated  with  the facsimile modem.  This
776              string is used to generate the Transmitter Subscriber  Identifi‐
777              cation (TSI) and Caller Subscriber Identification (CSI) informa‐
778              tion passed to remote machines—unless the LocalIdentifier param‐
779              eter  is explicitly set.  The FAXNumber is also used to name the
780              session log file where information for incoming phone  calls  is
781              recorded;  see  hylafax-log(5F).   If this phone number is not a
782              fully qualified number the values of  AreaCode  and  CountryCode
783              are used to generate the transmitted CSI and TSI.
784
785       Include²
786              Include  the  specified  config  file as if it were part of this
787              config file.
788
789       InternationalPrefix²
790              The string to use to place an international phone call.  In  the
791              United  States,  this  is ``011''.  This string is passed to the
792              dial string rules.
793
794       JobControlCmd¹
795              The command to invoke to which provides Job Control  information
796              for a job. See jobcontrol(8C).
797
798       JobReqBusy
799              The delay in seconds to wait before retrying a job whose dialing
800              attempt failed with a ``BUSY'' status result.
801
802       JobReqDataConn
803              The delay in seconds to wait before  retrying  a  facsimile  job
804              whose  dialing  attempt failed because a data modem answered the
805              phone.
806
807       JobReqNoAnswer
808              The delay in seconds to wait before retrying a job whose dialing
809              attempt failed with a ``NO ANSWER'' status result.
810
811       JobReqNoCarrier
812              The delay in seconds to wait before retrying a job whose dialing
813              attempt failed with a ``NO CARRIER'' status result.
814
815       JobReqNoFCon
816              The delay in seconds to wait before  retrying  a  facsimile  job
817              whose  dialing attempt failed because the initial facsimile pro‐
818              tocol handshake failed (i.e. no ``+FCON:'' result  was  received
819              from a Class 2/2.0 modem).
820
821       JobReqOther²
822              The  delay  in seconds to wait before retrying a job that failed
823              for a reason not already covered by one of the  JobReq*  parame‐
824              ters.
825
826       JobReqProto
827              The  delay  in  seconds  to wait before retrying a facsimile job
828              that failed because of a fax protocol error.
829
830       JobRetryBusy
831              The number of times to redial a phone number after  receiving  a
832              ``BUSY''  result  code when the number has not been successfully
833              dialed before.
834
835       JobRetryDataConn
836              The number of times to redial a phone number after  the  dialing
837              attempt  failed because a data modem answered the phone when the
838              number has not been successfully dialed before.
839
840       JobRetryNoAnswer
841              The number of times to redial a phone number after  the  dialing
842              attempt failed because of NO ANSWER when the number has not been
843              successfully dialed before.
844
845       JobRetryNoCarrier
846              The number of times to redial a phone number after  the  dialing
847              attempt  failed  because  of  NO CARRIER when the number has not
848              been successfully dialed before.  In normal  operation  the  fax
849              server  will treat this result code to mean that a facsimile mo‐
850              dem/machine did not answer the phone  and  reject  the  transmit
851              job.   This is done to avoid repeatedly dialing wrong phone num‐
852              bers and depends on the modem distinguishing between no  carrier
853              and no answer.  However, some modems are not capable of reliably
854              distinguishing between no carrier and no  answer,  or  when  in‐
855              structed  to do so do not identify a busy signal correctly.  For
856              these modems one may find it necessary to increase the value  of
857              this  parameter to compensate.  It is strongly recommended, how‐
858              ever, that this value not be set to a large number.
859
860       JobRetryOther
861              The number of times to redial a phone number after  the  dialing
862              attempt  failed  for  a reason not already covered by one of the
863              other JobRetry* parameters when the number has not been success‐
864              fully dialed before.
865
866       GettyArgs
867              A  string that indicates whether or not the server should invoke
868              the getty(8C) program in response to an  incoming  call  from  a
869              data  modem.  If the string value is not null, then it is inter‐
870              preted as a set of arguments to pass to the getty program.   Be‐
871              fore  supplying  the  arguments, the string is first scanned for
872              ``%''-escape sequences: any appearance  of  ``%l''  is  replaced
873              with  the tty name and any appearance of ``%s'' is replaced with
874              the serial port speed (in decimal).  Any appearance  of  escaped
875              numbers  1 through 9 (``%1'' through ``%9'') are replaced by the
876              match to the corresponding CallIDPattern, if present.  The ``%''
877              character can be specified with ``%%''.  If the GettyArgs param‐
878              eter is not specified in the configuration file or if the string
879              value  is  null,  then  data connections will be rejected.  Note
880              that in addition to the specified command  line  arguments,  the
881              getty  program  is  invoked with its standard input, output, and
882              error descriptors directed to the controlling tty device.
883
884       LocalIdentifier
885              The local station identification string to use when transmitting
886              TSI  and  CSI  strings  (see  FAXNumber  above).  NB: while this
887              string may contain any printable ASCII characters;  beware  that
888              CCITT  T.30  specifies  a  restricted character set and some fax
889              modems and machines may reject or  not  display   non-conforming
890              strings.   If the local identifier is not specified, a canonical
891              form of the FAXNumber is used instead.
892
893       LockDataCalls
894              Hold the UUCP lockfile during the time an inbound data  call  is
895              processed  by  the  external getty program.  If this is disabled
896              then the lockfile will be removed just before the getty  program
897              is invoked.  Note however that doing this introduces a race con‐
898              dition whereby an outbound program may sneak in and take control
899              of  the  modem after the inbound call has been accepted, but be‐
900              fore the getty program has started up  and  installed  it's  own
901              lockfile.
902
903       LockVoiceCalls
904              Hold  the  UUCP lockfile during the time an inbound data call is
905              processed by the external voice getty program.  If this is  dis‐
906              abled  then  the  lockfile will be removed just before the voice
907              getty program is invoked.  Note however that doing  this  intro‐
908              duces  a race condition whereby an outbound program may sneak in
909              and take control of the modem after the inbound  call  has  been
910              accepted,  but before the voice getty program has started up and
911              installed it's own lockfile.
912
913       LogFacility²
914              The symbolic name for the syslog(3) facility to use when logging
915              error  messages  and  informational/debugging messages requested
916              through the ServerTracing parameter.  The list of facility names
917              is  standardized;  it  can  be  found in the system include file
918              <syslog.h>; comparisons are case-insensitive.
919
920       LogCalls
921              Log all incoming calls into xferfaxlog as  CALL  records.   This
922              allows  a  quick  check of all incoming calls, regardless of fax
923              completion or not in a unified manner with other fax logs.
924
925       LogFileMode
926              The file protection mode that should be used when creating files
927              to  hold  session logs.  Note that this value is given in octal.
928              The default value of 0600 implies that the  log  files  are  not
929              generally  accessible,  which is important if sensitive informa‐
930              tion such as calling card access codes are logged.  If log files
931              are  to be publicly accessible, this value may be set, for exam‐
932              ple, to 0644.  See also chmod(2).
933
934       LogRecv
935              Log all recieved faxes into xferfaxlog as RECV records.
936
937       LogSend
938              Log all sent faxes into xferfaxlog as SEND records.
939
940       LongDistancePrefix²
941              The string to use to place a long distance phone call.   In  the
942              United States, this is ``1''.
943
944       MaxConcurrentCalls¹
945              The  default value to use for the maximum number of jobs for the
946              same destination that are processed concurrently.  Thus this pa‐
947              rameter  defines the maximum number of concurrent phone calls to
948              the same destination.  Unless all of your fax destinations  have
949              multiple  fax  lines  using  the same fax number per destination
950              then MaxConcurrentCalls is probably best left as the default  of
951              1 and exceptions should be accommodated by the JobControl mecha‐
952              nism.  However, for  high-throughput  applications  the  special
953              value  of  ``0''  may  be used; this configuration instructs the
954              server to permit limitless concurrent calls to the same destina‐
955              tion  provided  that all existing calls to that destination have
956              connected.  In this configuration if a busy  signal  is  encoun‐
957              tered  for a concurrent call then the various ``dials'' counters
958              are not incremented, and further concurrent calls are  temporar‐
959              ily stalled.
960
961       MaxConcurrentPreps¹
962              The maximum number of jobs preparations that may be run simulta‐
963              neously.  This is designed to prevent the scheduler from  initi‐
964              ating  so many job preparations that the system resources become
965              constrained in the operations.
966
967       MaxBatchJobs¹
968              The maximum number of jobs to batch together in a single call.
969
970       MaxConsecutiveBadLines
971              The maximum number of consecutive erroneous rows of  image  data
972              that  the server will receive before it deems a page to have un‐
973              acceptable copy quality.  Setting this parameter to zero  causes
974              the server to not check the quality of received facsimile.  Fac‐
975              simile received with error-correction do not have  copy  quality
976              checking performed.  See also PercentGoodLines.
977
978       MaxDials¹
979              The  default  value  for  the maximum number of times the server
980              will place a call for an outbound job.  This value may be  over‐
981              ridden  by  rules  in the JobControl mechanism.  This feature is
982              completely distinct from the identically-named  feature  in  the
983              client-server  communication,  and  jobs triggering these limits
984              will be handled differently for each.  See also MaxTries.
985
986       MaxProxyJobs¹
987              The maximum number of jobs which can be  concurrently  delivered
988              to a proxy for transmission.  This limit is to prevent proxy use
989              from overwhelming available system processes.
990
991       MaxRecvPages
992              The maximum number of pages the server will accept in a received
993              facsimile before it aborts the session.
994
995       MaxSendPages¹
996              The  default  value  for  the maximum number of pages the server
997              will permit in a transmitted facsimile.  Outbound jobs that  ex‐
998              ceed  this  limit are rejected.  This value may be overridden by
999              rules in the JobControl mechanism.
1000
1001       MaxSetupAttempts
1002              The maximum number of times a HylaFAX server  program  will  at‐
1003              tempt to initialize a modem before considering it ``wedged''.
1004
1005       MaxTraversal¹
1006              The  maximum  depth  into the job queues that the scheduler will
1007              traverse in attempts to batch jobs together in  a  single  call.
1008              This  is intended to prevent the scheduler from wasting a lot of
1009              CPU in batching attempts when  the  job  queues  get  very  long
1010              (where batching is unlikely to be useful anyway).
1011
1012       MaxTries¹
1013              The  default  value  for  the maximum number of times the server
1014              will attempt to communicate with a remote site.  Note that for a
1015              call  to  be  counted against this limit, carrier must be estab‐
1016              lished; this is in contrast to the value of MaxDials which  lim‐
1017              its  the number of calls that will be placed on behalf of a job.
1018              This value may be overridden by rules in the  JobControl  mecha‐
1019              nism.  This feature is completely distinct from the identically-
1020              named feature in the client-server communication, and jobs trig‐
1021              gering  these  limits will be handled differently for each.  See
1022              also MaxDials.
1023
1024       MinAcceptedLineCount
1025              The minimum number of received scanlines allowed  on  an  ``OK''
1026              page.   The use of this setting prevents confirmation from being
1027              sent for very short pages.
1028
1029       MissedPageHandlingMethod
1030              (Class 1/1.0 only) Specifies how to react to a missed  page  re‐
1031              ceived from the remote sender: one of ``RTN'', ``PIN'', ``DCN'',
1032              or ``CFR''.
1033
1034              If a page is missed (where the modem does not train on the Phase
1035              C  carrier) in non-ECM mode then, like BadPageHandlingMethod, it
1036              can be somewhat difficult to inform the sender of the problem.
1037
1038              A setting of ``RTN'' is the proper behavior  that  fax  protocol
1039              employs to request that the sender retransmit the page after re‐
1040              training.  Unfortunately, however, some  senders  will  perceive
1041              this  as  a receipt confirmation and not retransmit the page. If
1042              senderConfusesRTN is set to ``yes'' in the  associated  hylafax-
1043              info(5F)  file  for  this  sender,  then this method will not be
1044              used.
1045
1046              A setting of ``PIN'' is the proper behavior  that  fax  protocol
1047              employs  to  request that the sender retransmit the page after a
1048              procedural interrupt.  However, procedural interrupts are rarely
1049              used  and  may  not  be  widely  supported  by other systems. If
1050              senderConfusesPIN is set to ``yes'' in the  associated  hylafax-
1051              info(5F)  file  for  this  sender,  then this method will not be
1052              used.
1053
1054              A setting of ``DCN'' should  trigger  a  call  abortion  by  the
1055              sender.   This  should clearly indicate a problem to the sender,
1056              although a retransmission attempt in  a  later  call  cannot  be
1057              guaranteed.
1058
1059              A  setting  of  ``CFR'' causes an out-of-spec behavior where the
1060              CFR signal is used in response to the post-page message.   While
1061              other HylaFAX senders should handle this signal to lead to a re‐
1062              transmision of the page without retraining,  most  senders  will
1063              disconnect  after receiving this signal as it is not a permitted
1064              response in Phase D, and the sender response will be  undefined.
1065              This method will only be used if it is explicitly configured for
1066              use.
1067
1068              Historically, HylaFAX has employed both ``RTN'' and ``DCN''  be‐
1069              haviors  by  default  with complaints using either.  The ``PIN''
1070              and ``CFR'' behaviors were developed in  order  to  evaluate  if
1071              other systems besides HylaFAX would tolerate them.
1072
1073              MissedPageHandlingMethod  is designed to allow the administrator
1074              the opportunity to vary between these options through the Dynam‐
1075              icConfig feature to acheive a more nuanced approach.
1076
1077       ModemGroup¹
1078              Define  a logical name for a set of modem devices.  This parame‐
1079              ter can be used to define a name that clients can use  to  refer
1080              to  a  collection  of  modems.   The syntax is ``<name>:<defini‐
1081              tion>'' where <name> is the name for the group and  <definition>
1082              is  of  the syntax ``[<limit>:]<regex>'' where <limit> is an op‐
1083              tional formatted expression of the limits  for  this  ModemGroup
1084              and  <regex>  is  a  regular  expression  that  faxq(8C) matches
1085              against known modems.  Presently <limit> only refers to a number
1086              that  is  the minimum number of modems in the group that must be
1087              left to stay idle (for receiving) after assigning an active  job
1088              to  the ModemGroup.  The default for <limit> is 0.  Thus for ex‐
1089              ample, the default modem to use for a job, any,  is  defined  as
1090              ``any:0:.*''.  This parameter may be specified multiple times to
1091              define multiple modem classes.  Modem classes may overlap.   The
1092              actual  set  of  modems in a modem class that are considered for
1093              use may vary based on which modems are believed to be ready  for
1094              use.
1095
1096       ModemPriority
1097              The scheduling priority to use for a modem.  Priority values are
1098              in the range 0 to 255 with lesser values signifying higher (more
1099              desirable)  priority.  The HylaFAX scheduler process assigns the
1100              highest priority modem that is ready for use when scheduling  an
1101              outbound job.
1102
1103              If multiple available modems in a job's selected ModemGroup have
1104              the same ModemPriority value, then the HylaFAX scheduler assigns
1105              jobs to them in a round-robin fashion.
1106
1107       NoAnswerVoice
1108              Whether  or  not  to disable the answering of calls indicated as
1109              voice (e.g. by DistinctiveRings ).
1110
1111       NoCarrierRetrys
1112              This is mapped onto JobRetryNoCarrier
1113
1114       ModemReadyState
1115              Define the state transmitted to the  HylaFAX  scheduler  process
1116              each time a modem is made ready by a faxgetty process.  State is
1117              one of: ``R'' (ready for use), ``B'' (busy),  ``D''  (down),  or
1118              ``E''  (exempt).  The modem state can be used to control whether
1119              or not modems are assigned to outbound jobs.  A modem's state is
1120              initially  set to ``R'' (ready).  Modem state can be dynamically
1121              changed with the faxstate(8C) program or by setting this config‐
1122              uration  parameter  with the faxconfig(8C) program.  The HylaFAX
1123              scheduler process will not assign jobs to a modem with a  Modem‐
1124              ReadyState  of  anything  other than ``R''.  The differences be‐
1125              tween ``B'', ``D'', and ``E'' are that ``B'' refers to a  tempo‐
1126              rary  condition  that will automatically clear in the passing of
1127              time (as if the modem were in-use with receiving a  fax);  ``D''
1128              refers to a condition that will not automatically clear (such as
1129              a wedged condition); and ``E'' refers to a  permanent  condition
1130              as  configured  by  the administrator (as for a receive-only mo‐
1131              dem).  If a user submits a job to a specific modem  that  has  a
1132              ModemReadyState  of ``B'' or ``D'' then the job will wait in the
1133              queue until the modem is made available or until the  job  times
1134              out.   In  contrast,  jobs  submitted to a specific modem with a
1135              ModemReadyState of ``E''  will  be  rejected  outright.   Exempt
1136              modems  should  be removed from any ModemGroup to which they be‐
1137              long (i.e. ``any'').
1138
1139       ModemRingResponse
1140              This can be used to cause the command  defined  by  ModemRingRe‐
1141              sponse  to  be  sent  to the modem after hearing at least Modem‐
1142              RingsBeforeResponse RINGs in order to receive DID-DTMF data, for
1143              example.
1144
1145       ModemRingsBeforeResponse
1146              This  defines the minimum number of RINGs that must be heard be‐
1147              fore ModemRingResponse is first sent to the modem.
1148
1149       NotifyCmd²
1150              The program to invoke to notify a client of a job status change;
1151              see notify(8C).
1152
1153       PageChop¹
1154              Whether  or not to automatically truncate trailing whitespace on
1155              pages of outbound facsimile (when possible).  If  page  chopping
1156              is  enabled, then pages with at least PageChopThreshold trailing
1157              whitespace on a page will be transmitted as a ``short page''  if
1158              the receiver is capable of accepting variable-length pages.  The
1159              possible values are: ``last'' to enable  chopping  of  the  last
1160              page  of each document, ``all'' to enable chopping of all pages,
1161              or ``none'' to disable page chopping.
1162
1163       PageChopThreshold¹
1164              The minimum amount of trailing whitespace that must  be  present
1165              on  a page before page chopping will be attempted; see PageChop.
1166              Note that this value is specified in inches.
1167
1168       PCL2FaxCmd¹
1169              The command to invoke to convert a HP-PCL document submitted for
1170              transmission to TIFF/F, suitable for transmission.
1171
1172       PercentGoodLines
1173              The minimum percentage of good rows of image data required for a
1174              received facsimile page to be deemed  to  have  acceptable  copy
1175              quality.   Setting  this  parameter to zero causes the server to
1176              not check the quality of received facsimile.  Facsimile received
1177              with  error-correction  do  not  have copy quality checking per‐
1178              formed.  See also MaxConsecutiveBadLines.
1179
1180       PollLockPokeModem
1181              When polling for the presence/removal of a UUCP  lockfile,  also
1182              test  to make sure the modem is still reachable.  This is useful
1183              for scenarios where the modem  is  apt  to  become  disconnected
1184              while the modem is idle, such as an external modem that may lose
1185              power, where the administrator wants notification of this (as  a
1186              ``wedged'' condition).
1187
1188       PollLockWait
1189              When  polling  for  the presence/removal of a UUCP lockfile, the
1190              time (in seconds) to wait between checks.  Lockfile polling  oc‐
1191              curs  to  ensure  the  fax  server  doesn't collide with another
1192              process using the modem.
1193
1194       PollModemWait
1195              The time (in seconds) to wait between checks for a modem to  be‐
1196              come  ready for use.  Modem polling occurs when a modem fails to
1197              reset cleanly.
1198
1199       PriorityScheduling
1200              Indicates whether the HylaFAX scheduler should utilize available
1201              priority  job  scheduling  mechanisms to enhance realtime execu‐
1202              tion, particularly with  Class  1  configurations  on  older  or
1203              slower systems.
1204
1205              Currently  PriorityScheduling  is available for IRIX, SVR/4, HP-
1206              UX, and POSIX-compliant (i.e. Linux) operating systems.  The de‐
1207              fault value varies to maintain traditional HylaFAX behavior.  On
1208              IRIX, SVR/4, and HP-UX systems where the  configure  script  de‐
1209              tects  one  of  the functions schedctl(), priocntl() or rtprio()
1210              the default is true.  The only other supported  priority  mecha‐
1211              nism  is  POSIX  sched_setscheduler(),  which  is used on Linux,
1212              OpenServer and possibly other systems.  On such systems, as well
1213              as on systems where no priority scheduling mechanism exists, the
1214              default is false."
1215
1216       PS2FaxCmd¹
1217              The command to invoke to convert a POSTSCRIPT document submitted
1218              for  transmission  to  TIFF/F,  suitable  for  transmission; see
1219              ps2fax(8C).
1220
1221       QualifyPWD
1222              A string that specifies whether or not the identity  of  calling
1223              facsimile  machines  should be checked against an access control
1224              list before receiving facsimile.   If  QualifyPWD  is  non-null,
1225              then  only  messages  from  facsimile machines identified in the
1226              file specified by the string (typically etc/passwd) will be  ac‐
1227              cepted; similar to QualifyTSI.
1228
1229       QualifyTSI
1230              A  string  that specifies whether or not the identity of calling
1231              facsimile machines should be checked against an  access  control
1232              list  before  receiving  facsimile.   If QualifyTSI is non-null,
1233              then only messages from facsimile  machines  identified  in  the
1234              file  specified  by  the  string (typically etc/tsi) will be ac‐
1235              cepted; see tsi(5F).  If QualifyTSI is not specified in the con‐
1236              figuration file, or the value is null, then all incoming facsim‐
1237              ile messages will be accepted.
1238
1239       RecvDataFormat
1240              The data format (compression scheme) to write received facsimile
1241              data when copy quality checking is performed on the host.  (When
1242              copy quality checking is not done by  the  server,  for  example
1243              when  error  correction protocol is used, the received facsimile
1244              data is written exactly as it is received from the modem.)   The
1245              format  may  be  one:  ``1-D  MH'',  ``2-D MR'', ``2-D MMR'', or
1246              ``adaptive''.  An ``adaptive'' format causes the  received  data
1247              to be written using the data format negotiated by the sender and
1248              receiver.  Note that while 2-D MMR is the  most  space-efficient
1249              data format the resultant file may not be viewable (certain com‐
1250              monly used programs do not properly read multi-strip  TIFF  with
1251              2-D MMR data).
1252
1253       RecvFileMode
1254              The file protection mode that should be used when creating files
1255              to hold incoming facsimile.  Note that this value  is  given  in
1256              octal.   The default value of 0600 implies that only the facsim‐
1257              ile user can read received facsimile.  If incoming facsimile are
1258              to  be  publicly accessible, this value may be set, for example,
1259              to 0644.  See also chmod(2).
1260
1261       RejectCall
1262              If this is set to true, the current call will not  be  answered,
1263              and  will  be rejected.  This option has no effect if set in the
1264              configuration file, but when set by the  DynamicConfig  program,
1265              controls the current call.  This options supersedes the obsolete
1266              QualifyCID option.
1267
1268       RingData
1269              A modem status string that identifies that an incoming  call  is
1270              for  data  use.  This string should be set when a phone line has
1271              been setup with distinctive ring service.  See also RingFax  and
1272              RingVoice.
1273
1274       RingExtended
1275              An  identifier  which matches the initial portion of an extended
1276              RING message sent by the modem to relay CID and/or DNIS data in‐
1277              stead of sending it formatted on separate lines.
1278
1279       RingFax
1280              A  modem  status string that identifies that an incoming call is
1281              for facsimile use.  This string should be set when a phone  line
1282              has been setup with distinctive ring service.  See also RingData
1283              and RingVoice.
1284
1285       RingsBeforeAnswer
1286              The number of rings to wait before answering the phone.  If this
1287              value  is  set to 0, then the phone will only be answered in re‐
1288              sponse to an explicit answer command; see faxanswer(8C).
1289
1290       RingTimeout
1291              If a ring is heard and the call is not answered, the time in  ms
1292              to wait before reinitializing the modem for the next call.
1293
1294       RingVoice
1295              A  modem  status string that identifies that an incoming call is
1296              for voice use.  This string should be set when a phone line  has
1297              been setup with distinctive ring service.  See also RingData and
1298              RingFax.
1299
1300       RTNHandlingMethod
1301              Specifies how to react to an RTN signal received  from  the  re‐
1302              mote:  one  of  ``Retransmit'',  ``Giveup'',``Ignore'', or ``Re‐
1303              transmit-Ignore''.
1304
1305              ``Retransmit'' assumes that the page is  not  received  success‐
1306              fully.   HylaFAX will make up to two additional attempts to send
1307              the page, decreasing signalling rate  and  retraining.   If  RTN
1308              continues,  up  to 2 additional calls will be placed.  The down‐
1309              side is that if the remote always responds with  RTN,  the  page
1310              will  be sent 9 times and no following pages will be sent.  Many
1311              fax machines will not behave this way, although T.30  specifica‐
1312              tion seems clear that this is the intent of the RTN signal.
1313
1314              Some  fax machines will interpret RTN as meaning to not send the
1315              same data again.  That is because RTN may indicate problems with
1316              flow  control,  incorrectly encoded T.4 data, or some incompati‐
1317              bility other than line noise.  Fax machines that  interpret  RTN
1318              this  way  will  disconnect and require a manual retransmission.
1319              This  ``over  and  out''  behavior  can  be  activated  by   the
1320              ``Giveup''  value.   The  advantage to this behavior is that the
1321              same page of image data will not be sent multiple times, but the
1322              downside is that the following pages will not be sent.
1323
1324              ``Ignore'' is similar to ``Giveup'' in that it makes the assump‐
1325              tion the data cannot be automatically accepted by the  receiver.
1326              However,  rather  than  disconnecting  the page of image data is
1327              abandoned and processing moves on to the next.   The  remote  is
1328              left  to  decide  what to do with the unacceptable page of image
1329              data.  The downside to this behavior, is that the remote may  or
1330              may  not  have kept the page, depending on its interpretation of
1331              the RTN signal - but it does allow us to continue on to the next
1332              page.
1333
1334              ``Retransmit-Ignore''  is  a  combination  of ``Retransmit'' and
1335              ``Ignore''.  The page of image data is retransmitted up  to  two
1336              additional  times,  but  rather than disconnecting after a third
1337              RTN signal for the same page, processing then  continues  on  to
1338              the  next  page.  This approach is an effort to satisfy both in‐
1339              terpretations of an RTN signal.  It allows the receiver to hope‐
1340              fully  receive a better copy of the image data while not failing
1341              to send subsequent pages.  If the receiver  saves  or  prints  a
1342              copy  of pages for which it transmits RTN, then it could save or
1343              print up to three copies of every page.
1344
1345       SaveUnconfirmedPages
1346              Whether or not to save a received facsimile image  page  if  the
1347              sender  disconnects without sending the post-page message, with‐
1348              out hearing our message confirmation, without retraining as  re‐
1349              quested,  or  otherwise breaks fax protocol following such pages
1350              for which the sender should not have a ``receipt confirmation''.
1351
1352       SendFaxCmd¹
1353              The command to use  to  process  outbound  facsimile  jobs;  see
1354              faxsend(8C).
1355
1356       SendPageCmd¹
1357              The  command  to  use  to process outbound pager jobs; see page‐
1358              send(8C).
1359
1360       SendUUCPCmd¹
1361              The command to use to process outbound UUCP jobs.  This  parame‐
1362              ter is not currently used, it is for future development.
1363
1364       ServerTracing²
1365              A  number that controls the generation of tracing information by
1366              a server when  not  actively  sending  or  receiving  facsimile.
1367              Tracing  is divided into areas that are individually controlled.
1368              To enable tracing of multiple areas of operation, the flag asso‐
1369              ciated  with  each area should be bit-or'd to form the value for
1370              this tag.

1392              For example, to enable tracing of server operations and protocol
1393              operations,  a  value of 1+2=3 should be specified.  NB: tracing
1394              timeouts and/or binary modem I/O can adversely affect the opera‐
1395              tion of the fax server; enabling these areas should be done with
1396              extreme care.
1397
1398              Server tracing is directed to syslog(3) using the facility spec‐
1399              ified  with  the LogFacility configuration parameter.  Note that
1400              syslogd(8C) must be configured to capture facility.info,  facil‐
1401              ity.debug, facility.warning, and facility.err messages.  See hy‐
1402              lafax-log(5F) for a description of the logged messages.
1403
1404       SessionTracing²
1405              A number that controls the generation of tracing information  by
1406              a  server  while  sending or receiving facsimile.  The number is
1407              interpreted identically to  ServerTracing.   Note  that  session
1408              tracing  is placed in log files in the log subdirectory; see hy‐
1409              lafax-log(5F) for more information.
1410
1411       ShareCallFailures²
1412              A string which indicates the types of call failures that  should
1413              be  shared  to blocked jobs (in the scheduler config file) or to
1414              batched jobs (in the per-device configuration files).  The  pur‐
1415              pose  of this configuration is to prevent a large set of jobs to
1416              the same destination from stalling for long periods of  time  in
1417              the queue and repeatedly initiating failed delivery attempts due
1418              to call-related errors (such as an incorrectly-entered  destina‐
1419              tion  number).   Jobs which are batched or blocked (depending on
1420              which configuration file is used) will receive the same  failure
1421              indication  and  ``dials'' increment as the job which was active
1422              and running at the time (or lead the batch).   ShareCallFailures
1423              may  contain  the  following  key  words  in  any order with any
1424              deliniation:
1425
1426              Key Word    Meaning
1427              busy        Busy signal detected
1428              nocarrier   No carrier detected
1429              noanswer    No answer from remote
1430              nodialtone  No local dialtone
1431
1432              Alternatively, ShareCallFailures may be  set  exactly  to  ``al‐
1433              ways''  which  makes  it  apply to all of the call failure types
1434              listed above and is synonymous with  ``busy  nocarrier  noanswer
1435              nodialtone''.
1436
1437       SpeakerVolume
1438              The volume level that the in-modem speaker should be adjusted to
1439              while in command mode.  The possible values are:
1440              Value     Description
1441              Off       silent
1442              Quiet     almost inaudible
1443              Low       tolerable in privacy
1444              Medium    loud enough to hear in the next room
1445              High      intolerable
1446              Note that the speaker is always turned off once carrier  is  es‐
1447              tablished.   Also  beware  that some modems support fewer volume
1448              settings; see ModemSetVolumeCmd.
1449
1450       StaggerCalls¹
1451              The time, in seconds, to delay between initiating  outbound  job
1452              calls.   If HylaFAX is using a single phone line shared for both
1453              sending and receiving of faxes using a StaggerCalls setting  of,
1454              for  example,  300  would  ensure that outbound calls be made in
1455              succession no more frequently than every 5 minutes, thus  allow‐
1456              ing time between jobs for incoming calls to be received.
1457
1458       TagLineFont
1459              The  filename of the font to use in imaging tag lines across the
1460              top of each transmitted page.  Fonts must be stored in the  Por‐
1461              table  Compiled Font (PCF) format used by the X11 Window System.
1462              Filenames are specified relative to the  root  of  the  spooling
1463              area;  e.g. etc/lutRS18.pcf or etc/LiberationSans-25.pcf.  If no
1464              font is specified, if a null filename is specified,  or  if  the
1465              specified  font file is not readable, then tag lines will not be
1466              generated.  Note that the etc/lutRS18.pcf TagLineFont  that  has
1467              historically  been the default with HylaFAX does not have glyphs
1468              available beyond basic ASCII, and to show non-ASCII characters a
1469              different  file  must be used that has characters matching those
1470              characters found in TagLineFormat as decoded by  the  TagLineLo‐
1471              cale setting.  For this reason, the etc/LiberationSans-25.pcf is
1472              now considered the default as it has unicode support for  Latin,
1473              Greek, and Cyrillic characters.
1474
1475       TagLineFormat
1476              The  format  string to use when imaging tag lines across the top
1477              of each transmitted page.  This string may include escape  codes
1478              that  cause various items to be interpolated into the imaged tag
1479              line.  Any escape code supported by strftime(3C)  (which  use  a
1480              single ``%'') may be used as well as the following server-imple‐
1481              mented codes:
1482              Escape    Description
1483              %%a       destination subaddress
1484              %%c       destination company name
1485              %%C       sender's company name
1486              %%d       destination phone number
1487              %%g       sender's geographic location
1488              %%G       destination geographic location
1489              %%i       job identifier
1490              %%I       group identifier
1491              %%j       user-specified job tag
1492              %%l       job TSI or LocalIdentifier or canonicalized FAXNumber
1493              %%m       sender's electronic mail address
1494              %%n       canonicalized FAXNumber
1495              %%p       current page number of session
1496              %%P       current page number of job
1497              %%r       receiver's name
1498              %%s       sender's name
1499              %%S       subject
1500              %%t       total pages in session
1501              %%T       total pages in job
1502              %%v       sender's voice number
1503              %%V       destination voice number
1504              %%%       ``%''
1505              There are  numerous  date  and  time  format  options  available
1506              through strftime(3C).  Users are encouraged to refer to its doc‐
1507              umentation for elaboration.  Used by default, ``%c'' is  defined
1508              as  ``The preferred date and time representation for the current
1509              locale.''
1510
1511              In addition, the format string may indicate that text is  to  be
1512              broken  into multiple equal-sized fields by separating text with
1513              ``|'' characters.  If the first character  in  the  field  is  a
1514              ``{''  then  the text is left-aligned; if the first character in
1515              the field is a ``}'' then the text is right-aligned;  otherwise,
1516              the  text  is  centered  in the field.  For example, ``{a|b|}c''
1517              would cause the tag line to be broken up into three  equal-sized
1518              areas  with  the  string ``a'' left-aligned in the first region,
1519              ``b'' centered in the second region, and ``c'' right-aligned  in
1520              the  third region.  The default tag line format string is ``From
1521              %%n|%c|Page %%P of %%T''.  The differences between  the  %%p  or
1522              %%P and the %%t or %%T options are noticed when a fax job is re‐
1523              tried after an incomplete attempt and only the previously unsent
1524              pages  are  then  queued  in  a  successive  session.   See also
1525              TagLineFont.
1526
1527       TagLineLocale
1528              The locale setting  for  handling  TagLineFormat,  for  example,
1529              ``en_US.UTF-8''.  If TagLineFormat is encoded via UTF-8 then the
1530              correct setting of TagLineLocale is requisite for proper  decod‐
1531              ing  by  the  parser.   By  default the environment settings are
1532              used.
1533
1534       TIFF2FaxCmd²
1535              The command to invoke to convert a TIFF submitted for  transmis‐
1536              sion to TIFF/F, suitable for transmission; see tiff2fax(8C).  In
1537              the scheduler configuration file this is used  in  outbound  job
1538              preparation.  In the per-device configuration files this is used
1539              in conjunction with RTFCC features for comparing  relative  data
1540              sizes between different formats.
1541
1542       TimeOfDay¹
1543              The  default time-of-day restrictions to apply to outbound jobs.
1544              Outbound jobs will be processed only during the specified  time.
1545              Any  jobs  submitted outside this time period will be held until
1546              the start of this time.  The syntax for time-of-day restrictions
1547              is  designed  to  be compatible with the syntax used by the UUCP
1548              software.  The following BNF describes the syntax:
1549                 Syntax = tod ["," tod]
1550                    tod = <days><timerange>
1551                   days = "Any" | "Wk" | <dayname>+ | nothing
1552                dayname = "Sun" | "Mon" | "Tue" | "Wed" | "Thu" | "Fri" | "Sat"
1553              timerange = <start> "-" <end> | nothing
1554                  start = <24hrtime>
1555                    end = <24hrtime>
1556               24hrtime = {0-9}{0-9}{0-9}{0-9}
1557                nothing =
1558              where start and end are 24-hour times, day names can  be  either
1559              2-  or  3-characters, and a null day or time specification means
1560              any time or day.  White space and other syntactic sugar  may  be
1561              freely  inserted  between tokens but may not be inserted between
1562              24-hour times in the time range.
1563
1564              This value may be overridden by rules in the  JobControl  mecha‐
1565              nism.
1566
1567       TSIRecvdCmd
1568              The  pathname  of  the  optional program, e.g. ``etc/tsirecvd'',
1569              that similar to DynamicConfig can set the RejectCall  option  to
1570              cause  the  current  call  to  be rejected instead of continued.
1571              TSIRecvdCmd should provide a more capable mechanism than  Quali‐
1572              fyTSI  for  those wishing to screen calls based on received TSI.
1573              Note that this file must be marked as executable by the faxgetty
1574              process.  Note also that any configuration modifications made by
1575              the TSIRecvdCmd script other than RejectCall is unsupported  and
1576              has undefined results.
1577
1578       Unblock¹
1579              Intended  to  only  be used from the faxconfig(8C) utility, this
1580              will force faxq(8C) to unblock one call to  the  value-specified
1581              destination  number.   The destination number should be provided
1582              in the format known by faxq(8C), as seen in the hylafax-info(5F)
1583              database files.
1584
1585       Use2D¹ Control the use of 2D-encoded data for transmitted facsimile.
1586
1587       UseJobTagLine
1588              Allow  the  use of the job-specified tagline instead of the con‐
1589              figured TaglineFormat
1590
1591       UUCPLockMode²
1592              The file protection mode that should be used when creating  UUCP
1593              lockfiles.  Note that this value is given in octal.
1594
1595       UUCPLockDir²
1596              The  pathname of the directory in which UUCP lockfiles are to be
1597              created.
1598
1599       UUCPLockTimeout²
1600              The time in seconds to wait before removing a stale  UUCP  lock‐
1601              file (i.e. a lockfile whose owner does not appear to exist).  If
1602              this value is set to 0, then the fax server will never remove  a
1603              stale lockfile.
1604
1605       UUCPLockType²
1606              A  string  that  specifies  the type of UUCP lockfile to create.
1607              The string may be one of ``ascii'' or  ``binary''  depending  on
1608              whether  the process-ID of the lock owner is written to the file
1609              as an ascii string or as a binary value, respectively.  In addi‐
1610              tion, two prefixes may be used to control the format of the lock
1611              filename.  If the type string is prefixed  with  a  ``+'',  then
1612              SVR4-style filenames are generated using the major device number
1613              of the tty device and the major and minor device numbers for the
1614              filesystem  on which the tty device resides.  If the type string
1615              is prefixed with a ``-'', then any upper case letters in the de‐
1616              vice  part of the lockfile name are converted to lower case let‐
1617              ters;   for   example,   ``LCK..ttyA01''   is    converted    to
1618              ``LCK..ttya01''.   This upper-to-lower case conversion is useful
1619              for systems such as SCO where the convention is to name  devices
1620              with  upper-case  letters,  but create lockfiles with lower-case
1621              letters.
1622
1623       VGettyArgs
1624              A string that indicates whether or not the server should  invoke
1625              a voice getty program in response to an incoming voice call.  If
1626              the string value is not null, then it is interpreted as a set of
1627              arguments  to  pass to the vgetty program.  Before supplying the
1628              arguments, the string is  first  scanned  for  ``%''-escape  se‐
1629              quences:  any appearance of ``%l'' is replaced with the tty name
1630              and any appearance of ``%s'' is replaced with  the  serial  port
1631              speed (in decimal).  Any appearance of escaped numbers 1 through
1632              9 (``%1'' through ``%9'') are replaced by the match to the  cor‐
1633              responding  CallIDPattern,  if present.  The ``%'' character can
1634              be specified with ``%%''.  If the VGettyArgs  parameter  is  not
1635              specified  in  the  configuration file or if the string value is
1636              null, then voice connections will be rejected.  Note that in ad‐
1637              dition  to the specified command line arguments, the vgetty pro‐
1638              gram is invoked with its standard input, output, and  error  de‐
1639              scriptors directed to the controlling tty device.
1640
1641       WedgedCmd¹
1642              The  program  to  invoke  when a modem is deemed ``wedged''; see
1643              wedged(8C).
1644

MODEM-ORIENTED CONFIGURATION PARAMETERS

1646       This section lists configuration parameters that are  specific  to  the
1647       setup  and  operation of the modem.  All commands must be specified ex‐
1648       actly as they are to be transmitted to the modem (note that this  is  a
1649       departure  from  previous  versions of this software that automatically
1650       prepended ``AT'' to each line of commands sent  to  the  modem).   When
1651       multi-line  commands  are required, enclose the commands in quote marks
1652       (``"'') and insert a newline character ``\n''  where  lines  should  be
1653       broken.     An    example   of   a   multi-line   command   string   is
1654       ``AT+FCQ=1\nAT+FBADMUL=20\nAT+FBADLIN=10''.
1655
1656       Command strings sent to the modem  may  include  command  escapes  that
1657       force  the  host to alter the DTE-DCE communication rate, the flow con‐
1658       trol scheme used between the host and modem,  delay  for  a  period  of
1659       time,  flush  input data, and wait for a specific response from the mo‐
1660       dem.  The following escape codes are interpreted:
1661              Escape      Effect
1662              <none>      enable no flow control between DTE and DCE
1663              <xon>       enable software flow control between DTE and DCE
1664              <rts>       enable hardware flow control between DTE and DCE
1665              <2400>      set the DCE-DTE baud rate to 2400 bps
1666              <4800>      set the DCE-DTE baud rate to 4800 bps
1667              <9600>      set the DCE-DTE baud rate to 9600 bps
1668              <19200>     set the DCE-DTE baud rate to 19200 bps
1669              <38400>     set the DCE-DTE baud rate to 38400 bps
1670              <57600>     set the DCE-DTE baud rate to 57600 bps
1671              <76800>     set the DCE-DTE baud rate to 76800 bps
1672              <115200>    set the DCE-DTE baud rate to 115200 bps
1673              <delay:N>   delay N x 10 ms on the host (0 <= N <= 255)
1674              <flush>     flush any pending input data from the modem
1675              <waitfor:R> wait for the response R from the modem (see below)
1676              <play:C>    play the etc/playC.raw audio file (see below)
1677       Note that commands to the left of an escape code are sent to the  modem
1678       before the associated actions are carried out on the host.  This may be
1679       important when changing baud rates, as the result code from  a  command
1680       may  be  returned at the new baud rate.  Also, beware that not all baud
1681       rates are supported by all systems and modems; the set  of  baud  rates
1682       supported by a host is usually listed in stty(1).
1683
1684       The  ``<waitfor:..>'' escape can be used to override the default behav‐
1685       ior which is to wait for an ``OK'' response to a command  sent  to  the
1686       modem.  The possible response codes are:
1687              NOTHING       a null response
1688              OK            the default response
1689              CONNECT       ``CONNECT...''
1690              NOANSWER      ``NO ANSWER...''
1691              NOCARRIER     ``NO CARRIER...''
1692              NODIALTONE    ``NO DIALTONE...''
1693              BUSY          ``BUSY''
1694              OFFHOOK       ``PHONE OFF-HOOK''
1695              RING          ``RING...''
1696              ERROR         error status from modem
1697              VCON          voice connection indicator
1698              OTHER         any unrecognized modem response
1699       For  example ``ATO\r<waitfor:CONNECT>'' would send ``ATO\r'' to the mo‐
1700       dem and then wait for a response with a leading ``CONNECT'' in it;  and
1701       ``ATS99=2\r<delay:2><flush><waitfor:NOTHING>'' would send ``ATS99=2\r''
1702       to the modem, delay 20 ms, flush any input from  the  modem,  and  then
1703       continue (not wait for any response).
1704
1705       The  ``<play:C>''  escape  can  be used to play a raw audio file with a
1706       voice modem.  The files are named  etc/playC.raw  where  ``C''  is  any
1707       character.   This feature can be used, for example, to play a brief au‐
1708       dio message after picking up the line but before answering.  A configu‐
1709       ration example may be:
1710
1711         ModemRingResponse:  "AT+FCLASS=8;H1\nAT+VSM=131\nAT+VLS=1\nAT+VTX\n<waitfor:CONNECT><play:1><waitfor:OK>AT+VTS=[933,,150]"
1712         ModemAnswerCmd:     "<delay:100>AT+FCLASS=1;A"
1713         CallIDPattern:      SHIELDED_DTMF
1714         CallIDAnswerLength: 4
1715
1716       In  this  example using an IS-101 voice-compliant modem, a RING indica‐
1717       tion from the modem will cause the modem to be placed  in  voice  mode,
1718       set  ulaw audio compression, and via the connected phone line play back
1719       the etc/play1.raw audio file, which may say, "After the  tone  enter  a
1720       four-digit  extension,  then  start  the fax."  Following the message a
1721       tone is played.
1722
1723       ModemAnswerCmd
1724              The command to answer the  phone.   If  possible,  this  command
1725              should  generate a result string that identifies whether the in‐
1726              coming call is from a facsimile, voice, or  data  modem.   Typi‐
1727              cally this auto-detection is configured ahead of time; e.g.  for
1728              Class 2 modems with the ``AT+FAA=1'' command.
1729
1730              The following table describes how the result  codes  are  inter‐
1731              preted by the facsimile server.
1732              Result String    Default          Class 1      Class 2      Class2.0

1746              The ``Default'' column indicates the interpretation made for the
1747              result string in either class 1 or 2 unless explicitly  overrid‐
1748              den.   The  ``Class  1'' column indicates result strings handled
1749              specially for modems operating in class 1, the ``Class 2''  col‐
1750              umn  indicates special handling for modems operating in class 2,
1751              and the ``Class 2.0''  column  indicates  special  handling  for
1752              modems  operating  in class 2.0.  Unknown entries imply that in‐
1753              terpretation is based on the way in which the call was answered;
1754              if answering is done for an explicit call type, that type is as‐
1755              sumed, otherwise a Fax call is presumed.
1756
1757       ModemAnswerAgainCmd
1758              The command to answer the phone  if  ModemAnswerCmd  appears  to
1759              have been ignored.  Typically this should include a delay escape
1760              in order to set the timing of the answer away from the  ring  in
1761              case  the  modem  is incapable of answering so closely following
1762              the ring.
1763
1764       ModemAnswerDataBeginCmd
1765              The command to send to the modem once a data connection has been
1766              established.
1767
1768       ModemAnswerDataCmd
1769              The  command  to  explicitly answer the phone for a data connec‐
1770              tion.  This command must generate a result string  that  identi‐
1771              fies  the incoming call is from a data modem.  If this parameter
1772              is not specified or is null, then the value of ModemAnswerCmd is
1773              used instead.  See also AdaptiveAnswer and AnswerRotary.
1774
1775       ModemAnswerDialCmd
1776              The  command to explicitly answer the phone for a dialed connec‐
1777              tion.  This command must generate a result string  that  identi‐
1778              fies  the  incoming call is from a facsimile modem.  If this pa‐
1779              rameter is not specified or is null, then the value of  ModemAn‐
1780              swerCmd is used instead.
1781
1782       ModemAnswerFaxBeginCmd
1783              The command to send to the modem once a facsimile connection has
1784              been established.
1785
1786       ModemAnswerFaxCmd
1787              The command to explicitly answer the phone for a facsimile  con‐
1788              nection.   This command must generate a result string that iden‐
1789              tifies the incoming call is from a facsimile modem.  If this pa‐
1790              rameter  is not specified or is null, then the value of ModemAn‐
1791              swerCmd is used instead.  See also AdaptiveAnswer and  AnswerRo‐
1792              tary.
1793
1794       ModemAnswerVoiceBeginCmd
1795              The  command  to  send  to the modem once a voice connection has
1796              been established.
1797
1798       ModemAnswerVoiceCmd
1799              The command to explicitly answer the phone for a  voice  connec‐
1800              tion.   This  command must generate a result string that identi‐
1801              fies the incoming call is for voice.  If this parameter  is  not
1802              specified  or  is null, then the value of ModemAnswerCmd is used
1803              instead.  See also AdaptiveAnswer and AnswerRotary.
1804
1805       ModemAnswerResponseTimeout
1806              The maximum time, in milliseconds, to wait for a  response  from
1807              the  modem after sending ModemAnswerCmd.  Note that you may want
1808              to shorten this value when using the server-based  adaptive  an‐
1809              swer strategy; see AdaptiveAnswer.
1810
1811       ModemATCmdDelay
1812              A  delay,  in milliseconds, that should be performed before each
1813              ``AT'' command string is sent to the modem.
1814
1815       ModemBaudRateDelay
1816              The amount of time, in milliseconds, to pause after setting  the
1817              baud rate on the serial line.  This is only needed for hosts and
1818              modems (such as USRs) where setting the serial  line  parameters
1819              does not take effect immediately.
1820
1821       ModemCEDCmd
1822              The  command to signal CED and raise the V.21 HDLC transmit car‐
1823              rier after a session has started.  This is used after  a  proce‐
1824              dure  interrupt.   Normally  this command is ``ATA'', but if the
1825              modem does not permit ``ATA'' after a session has started,  then
1826              ``AT+FTH=3'' should probably be used, instead.
1827
1828       ModemCNGCmd
1829              The  command to signal CNG and listen for V.21 HDLC after a ses‐
1830              sion has started.  This is used  after  a  procedure  interrupt.
1831              Normally this command is ``ATD'', but if the modem does not per‐
1832              mit ``ATD'' after  a  session  has  started,  then  ``AT+FRH=3''
1833              should probably be used, instead.
1834
1835       ModemCommaPauseTimeCmd
1836              The  command  to set the time, in seconds, that the modem should
1837              pause when encountering a ``,'' modifier in the dialing string.
1838
1839       ModemDialCmd
1840              The command to place a phone call.  The string is assumed to  be
1841              suitable  for use as a parameter to the sprintf(3S) function; so
1842              the ``%'' character should be escaped as ``%%''.  The dial  com‐
1843              mand must include a single ``%s'' where the number that is to be
1844              dialed is to be substituted.  The command may include  a  single
1845              ``%d'' where the origin number is to be substituted.  Facilities
1846              such as tone or pulse dialing, outgoing prefixes to route though
1847              a  PBX,  and  so  on  should  be included in the dialing command
1848              string.  It is also important  that,  if  possible,  a  trailing
1849              ``@'' symbol should be included so that the modem returns result
1850              codes that distinguish between no answer and no carrier.  Use of
1851              the  ``@''  permits  the server to reduce the probability that a
1852              wrong number is continually redialed.  If  the  modem  does  not
1853              support  this  facility,  then  it may be necessary to raise the
1854              number of retries done when a ``NO CARRIER'' result is returned.
1855
1856       ModemDialResponseTimeout
1857              The maximum time to wait, in milliseconds, for a  response  from
1858              the  modem  after  sending  This value should be longer than the
1859              timeout programmed into the modem through  the  ModemWaitTimeCmd
1860              parameter.   This additional server-based timeout is provided to
1861              guard against modems that can ``lock up'' when dialing the tele‐
1862              phone.
1863
1864       ModemDoPhaseCDebug
1865              Whether  or  not  to  query the modem for responses during image
1866              data transmission.  Normally the modem should  not  produce  any
1867              responses  during  Phase  C data transmission.  However, in some
1868              debugging scenarios (i.e. some Class 2.1 modems may show  debug‐
1869              ging  information)  it may be appropriate to query the modem for
1870              responses during the data transmission.
1871
1872       ModemDTRDropDelay
1873              The time, in milliseconds, to pause between placing DTR OFF  and
1874              DTR  ON  while resetting a modem.  This value should be at least
1875              equal to the time-value of  the  analogous  S-register,  usually
1876              S25.   This  so-called DTR drop can be bypassed entirely by set‐
1877              ting ModemDTRDropDelay to 0, but this should likely only be used
1878              for debugging purposes.
1879
1880       ModemEchoOffCmd
1881              The command to disable echoing of commands sent to the modem.
1882
1883       ModemFlowControl
1884              The  type  of  flow  control  to use between DTE and DCE; one of
1885              ``NONE'', ``XONXOFF'' and ``RTSCTS''.  This value is used to se‐
1886              lect the string sent to the modem to initially establish DTE-DCE
1887              flow  control;  one  of  ModemNoFlowCmd,  ModemSoftFlowCmd,  and
1888              ModemHardFlowCmd.  The current flow control setting is also used
1889              to select the appropriate flow control command to  send  to  the
1890              modem  when  the  software  switches  to Class 1, 2, or 2.0; see
1891              Class1HFLOCmd,  Class1NFLOCmd,   Class1SFLOCmd,   Class2HFLOCmd,
1892              Class2NFLOCmd, and Class2SFLOCmd.
1893
1894              The  server supports both software and hardware flow control for
1895              Class 1, Class 2, and Class 2.0 modems.  Whether to use hardware
1896              or  software flow control depends on the capabilities of the mo‐
1897              dem and the host hardware and operating  system.   Communication
1898              rates  above  9600 baud often require that hardware flow control
1899              be used for reliable  DTE-DCE  communication.   However,  beware
1900              that many modems only support software flow control when sending
1901              or receiving facsimile.
1902
1903              Note that modems usually support software flow control  even  if
1904              they have no explicit AT-command to activate it; in this case it
1905              is  switched  on  when  the  modem  enters  fax   mode,   having
1906              AT+FCLASS=... from DTE.
1907
1908       ModemFrameFillOrder
1909              The bit order to expect for received HDLC frames and to use when
1910              formulating HDLC frames to  send.   This  value  may  be  either
1911              LSB2MSB  when  bits  are  ordered  from least-significant-bit to
1912              most-significant-bit (as in the CCITT specification) or  MSB2LSB
1913              when bits are ordered in the reverse direction.
1914
1915       ModemHardFlowCmd
1916              The command to setup hardware (RTS/CTS) flow control between DTE
1917              and DCE.
1918
1919       ModemMinSpeed
1920              The minimum acceptable signalling rate for transmitting  facsim‐
1921              ile  page  data.   Possible  values are: 2400, 4800, 7200, 9600,
1922              12200, and 14400.
1923
1924       ModemMfrQueryCmd
1925              The command to send to the modem to get the manufacturer identi‐
1926              fication  string.  If this parameter is not set, then it is ini‐
1927              tialized to ``AT+FMFR?'' for Class 2 modems, or  to  ``AT+FMI?''
1928              for Class 2.0 modems, or to ``ATI3'' for Class 1 modems.  If the
1929              parameter begins with a ``!'', then the remainder of the  string
1930              is  taken  to be the identification string and no command is is‐
1931              sued to the modem.
1932
1933       ModemModelQueryCmd
1934              The command to send to the modem to get the model identification
1935              string.  If this parameter is not set, then it is initialized to
1936              to ``AT+FMDL?'' for Class 2 modems, or to ``AT+FMM?'' for  Class
1937              2.0 modems, or to ``ATI0'' for Class 1 modems.  If the parameter
1938              begins with a ``!'', then the remainder of the string  is  taken
1939              to  be the identification string and no command is issued to the
1940              modem.
1941
1942       ModemNoAutoAnswerCmd
1943              The command to stop the modem from automatically answering  when
1944              the phone rings.
1945
1946       ModemNoAutoAnswerCmdDelay
1947              The  time, in milliseconds, to pause after receiving the OK fol‐
1948              lowing ModemNoAutoAnswerCmd before any further commands are sent
1949              to  the  modem.  All input from the modem is flushed after paus‐
1950              ing.
1951
1952       ModemNoFlowCmd
1953              The command to disable flow control between DTE and DCE.
1954
1955       ModemOnHookCmd
1956              The command to place the phone ``on hook'' (i.e. hangup).
1957
1958       ModemPageDoneTimeout
1959              The maximum time to wait, in milliseconds, for a  response  from
1960              the modem after sending a page of facsimile data (e.g.  the time
1961              to wait for a response to a Class 2/2.0 AT+FET command).
1962
1963       ModemPageStartTimeout
1964              The maximum time to wait, in milliseconds, for  an  initial  re‐
1965              sponse  from  the  modem  when  sending a page of facsimile data
1966              (e.g. the time to wait for a response to a  Class  2/2.0  AT+FDR
1967              command).
1968
1969       ModemRaiseATCommands
1970              Indicates  whether  or not all configuration AT commands for the
1971              modem should be raised to upper-case automatically.   The  stan‐
1972              dard  is  for  all upper-case to be used in AT commands, and in‐
1973              deed, some rare modems  have  been  known  to  malfunction  with
1974              lower-case  commands.   However,  sometimes an administrator may
1975              want to use lower-case commands in a rare condition such  as  to
1976              work around modem blacklisting of dialed numbers.
1977
1978       ModemRate
1979              The  baud rate to use for DCE-DTE communication.  This value may
1980              be one of: 115200, 76800, 57600, 38400, 19200, 9600, 4800, 2400,
1981              1200.   The  default value is 19200 because many modems lock the
1982              rate at 19200 when sending or receiving  facsimile.   Note  that
1983              not  all  values  are  supported  by  all  operating systems and
1984              modems; consult stty(1) for the available rates on your system.
1985
1986       ModemReadyCmds
1987              A string of commands to issue to the modem during reception ini‐
1988              tialization.   This  string is sent to the modem after the stan‐
1989              dard set of configuration commands required by the  fax  server.
1990              This  is  done, for example, to un-busy a DID line so that calls
1991              can come through.
1992
1993       ModemRecvFillOrder
1994              The bit order to expect for received facsimile data.  This value
1995              may  be either LSB2MSB when bits are ordered from least-signifi‐
1996              cant-bit to most-significant-bit (as in the CCITT specification)
1997              or  MSB2LSB when bits are ordered in the reverse direction.  Ac‐
1998              cording to the various specifications all modems  should  return
1999              data  in  LSB2MSB  order.   However  most Class 2 modems (except
2000              maybe only Multitech) use MSB2LSB for compatibility with  modems
2001              that  were built with Rockwell hardware/firmware that included a
2002              bug that was too widespread to correct.
2003
2004              If this parameter is not set, then it is autodetected and set to
2005              LSB2MSB  for  Class  1 and Class 2.0 modems and MSB2LSB for non-
2006              Multitech Class 2 modems. However this may be wrong for your mo‐
2007              dem, so you will have to specify this parameter explicitly.
2008
2009       ModemRecvSuccessCmd
2010              A  string  of  commands to issue to the modem after a successful
2011              receive session before the call is disconnected.
2012
2013       ModemResetCmds
2014              A string of commands to issue to the  modem  during  initializa‐
2015              tion.   This string is sent to the modem before the standard set
2016              of configuration commands required by the fax server.  Note that
2017              these commands should not include normal reset commands that are
2018              specified through other parameters.  For  example,  commands  to
2019              setup  flow  control, DCD handling, DTR handling, etc. should be
2020              specified through the appropriate configuration  parameters  and
2021              not  through this parameter.  In addition the soft reset command
2022              (usually ``ATZ'') should not be included  in  this  string;  the
2023              servers issue this command explicitly.
2024
2025       ModemResetDelay
2026              The  time, in milliseconds, to pause after setting DTR ON, while
2027              resetting a modem.  DTR ON does not respond with ``OK'', so this
2028              parameter  should  be  long enough to allow the modem time to be
2029              ready for ModemSoftResetCmd successively.
2030
2031       ModemResultCodesCmd
2032              The command to enable result codes.
2033
2034       ModemRevQueryCmd
2035              The command to send to the modem  to  get  a  firmware  revision
2036              identification string.  If this parameter is not set, then it is
2037              initialized  to  ``AT+FREV?''  for  Class  2   modems,   or   to
2038              ``AT+FMR?''  for Class 2.0 modems.  If the parameter begins with
2039              a ``!'', then the remainder of the string is  taken  to  be  the
2040              identification string and no command is issued to the modem.
2041
2042       ModemSecondAnswerCmd
2043              The command to send to the modem in the event that the first an‐
2044              swer command results with ``OK'' rather than  an  otherwise  ex‐
2045              pected  indication.   This command is intended to resume the an‐
2046              swer procedure where the first left off.
2047
2048       ModemSendBeginCmd
2049              The command to send to the modem upon establishing carrier  dur‐
2050              ing  a transmit operation.  This parameter is useful for systems
2051              that are incapable of enabling hardware flow control without DCD
2052              asserted.
2053
2054       ModemSendFillOrder
2055              The  bit order the modem expects for transmitted facsimile data.
2056              This value may be either LSB2MSB or MSB2LSB (see also ModemRecv‐
2057              FillOrder  above.)  Virtually all modems expect transmitted fac‐
2058              simile data in LSB2MSB bit order.
2059
2060       ModemSetOriginCmd
2061              The command to use to set the  call  origin  information  before
2062              placing  a  call.  The command may include a single ``%d'' where
2063              the job request ``faxnumber'' string is to be substituted.   The
2064              command  may  also include a single ``%s'' where the job request
2065              ``faxname'' string is to be subsituted.
2066
2067       ModemSetVolumeCmd
2068              The commands to use to set  the  modem  speaker  volume  levels.
2069              There should be five whitespace-separated commands, one each for
2070              setting the volume to ``Off'', ``Quiet'',  ``Low'',  ``Medium'',
2071              and  ``High'';  the  default  is  ``"ATM0  ATL0M1  ATL1M1 ATL2M1
2072              ATL3M1"''.  See also SpeakerVolume.
2073
2074       ModemSetupAACmd
2075              The command to setup adaptive answer  support  in  the  modem-if
2076              available.   Adaptive answer is the term used for the ability to
2077              distinguish  between  calls  from  facsimile,  voice,  and  data
2078              sources.   Note  that  this string is the last command issued by
2079              the device drivers during setup, so the command string  may,  if
2080              necessary,  switch  to  a different operating mode (e.g. on some
2081              Rockwell-based modems it is necessary to issue the  ``AT+FAA=1''
2082              command in Class 0).
2083
2084       ModemSetupDCDCmd
2085              The  command to setup DCD handling.  On most systems the facsim‐
2086              ile server will enable the CLOCAL flag  on  the  tty  device  to
2087              which  the modem is connected.  This should ensure that the sys‐
2088              tem does not close an open file descriptor associated  with  the
2089              modem  if carrier is dropped.  Thus, for most systems and modems
2090              ModemSetupDCDCmd should setup DCD to reflect carrier.
2091
2092       ModemSetupDTRCmd
2093              The command to setup DTR handling so that  the  modem  is  reset
2094              when  the  DTR  signal  is  lowered  by the host.  The facsimile
2095              server uses this facility to ensure that modems are not left  in
2096              a ``locked up'' state.
2097
2098       ModemSoftFlowCmd
2099              The  command  to  setup software (XON/XOFF) flow control between
2100              DTE and DCE.
2101
2102       ModemSoftResetCmd
2103              The command to force a soft reset of the modem.
2104
2105       ModemSoftResetCmdDelay
2106              The time, in milliseconds, to pause after receiving the OK  fol‐
2107              lowing ModemSoftResetCmd before any further commands are sent to
2108              the modem.
2109
2110       ModemSoftRTFCC
2111              Whether or not to enable software-driven Real-Time Fax  Compres‐
2112              sion Conversion.  RTFCC allows HylaFAX to convert the image com‐
2113              pression between MH MR and MMR formats regardless  of  how  faxq
2114              formatted  the image file.  Note that when using RTFCC, the com‐
2115              pression format of the file will be ignored,  thus  the  ``-1'',
2116              ``-2'',  and ``-3'' options for sendfax, ps2fax, and others will
2117              only influence how the document is prepared by faxq and will not
2118              influence the actual negotiated session parameters.  Class2RTFCC
2119              takes precedence over ModemSoftRTFCC and if  both  are  enabled,
2120              then software-driven RTFCC will not be performed in favor of the
2121              firmware-driven RTFCC.
2122
2123       ModemType
2124              This parameter must be set to one of: ``Class2'',  ``Class2.0'',
2125              ``Class1'',  or  ``Class1.0'';  to  indicate that the modem is a
2126              Class 2-, Class 2.0-, Class 1-, or Class  1.0-style  modem,  re‐
2127              spectively.   If this parameter is not set, then HylaFAX detects
2128              which classes are supported by the modem and makes  an  internal
2129              decision  on  which  to use.  Historically this decision chooses
2130              Class 2.1 over Class 2.0 over Class 2 over Class 1.0 over  Class
2131              1.  However, some exceptions are made, for instance, with US Ro‐
2132              botics modems where Class 2.0 support is avoided.
2133
2134       ModemVerboseResultsCmd
2135              The command to enable verbose, as  opposed  to  numeric,  result
2136              codes.
2137
2138       ModemWaitForConnect
2139              If  enabled, the facsimile server will not consider a connection
2140              established when answering an incoming call until a  ``CONNECT''
2141              status  string  is received.  This is useful mainly for Rockwell
2142              RC32ACL-based modems that send ``FAX'' and ``DATA'' status  mes‐
2143              sages before sending ``CONNECT''.
2144
2145       ModemWaitTimeCmd
2146              The  command  to set the number of seconds to wait for a carrier
2147              signal when placing a call or answering the phone.
2148

T.30 PROTOCOL CONFIGURATION PARAMETERS

2150       The following parameters apply to the implementation of the CCITT  T.30
2151       facsimile  protocol  in  the Class 1 device driver.  They should not be
2152       changed without full understanding of the operation of the server.
2153
2154       FaxT1Timer
2155              The value of the T1 timer in milliseconds.  This timer  is  used
2156              to  time  out  the  initial  session  contact;  i.e.  receipt of
2157              DIS/DCS.
2158
2159       FaxT2Timer
2160              The value of the T2 timer in milliseconds.  This timer  is  used
2161              to time out receiving responses and commands.
2162
2163       FaxT4Timer
2164              The  value  of the T4 timer in milliseconds.  This timer is used
2165              to time out the reception of HDLC frames and,  usually,  trigger
2166              frame retransmissions.
2167

CLASS 1 MODEM CONFIGURATION PARAMETERS

2169       The  following  parameters  are  specific to the configuration of Class
2170       1-style modems; they should not be changed lightly:
2171
2172       Class1Cmd
2173              The command to set the modem into Class 1 operation.
2174
2175       Class1AdaptRecvCmd
2176              The command used to enable adaptive reception  support  (usually
2177              ``AT+FAR=1'').   This  feature  is  new in T.31, and many modems
2178              will not support it.  This feature may reduce the number of  re‐
2179              ception failures due to errors cascading from +FCERROR messages.
2180
2181       Class10AutoFallback
2182              Whether  or not the modem implements an automatic fallback to G3
2183              mode if V.8 handshaking ANSam is not detected for  a  Class  1.0
2184              V.34-Fax (SuperG3) call.
2185
2186       Class1ColorJPEGSupport
2187              Whether or not to enable support for T.30-E full-color facsimile
2188              with JPEG  compression.   Enabling  this  automatically  enables
2189              Class1GreyJPEGSupport.
2190
2191       Class1EnableV34Cmd
2192              The command to enable V.34-fax support with at least the desired
2193              maximum primary channel rate.
2194
2195       Class1ECMCheckFrameLength
2196              Whether or not to require the frame length for ECM  data  frames
2197              to be complete when checking for frame integrity.  Normally this
2198              is not beneficial (and can be problematic for some senders), but
2199              in some cases the frame CRC is not reliable because of modem be‐
2200              havior.
2201
2202       Class1ECMSupport
2203              Whether or not to support T.30-A error correction protocol.  Use
2204              of ECM will require 64 kilobytes of free memory per modem in ac‐
2205              tive use.
2206
2207       Class1PersistentECM
2208              Whether or not to continue to retransmit and allow  to  continue
2209              to  receive  image data in ECM protocol which is not accepted as
2210              valid after four successive attempts.
2211
2212       Class1ECMFrameSize
2213              The size in bytes of image frames to transmit during ECM  proto‐
2214              col.   This  setting  will also indicate a preference in receive
2215              sessions.  The only acceptable values are 64 and 256.  A setting
2216              of  64  may be useful on high-load systems and possibly environ‐
2217              ments with extremely poor line quality.
2218
2219       Class1ExtendedRes
2220              Whether or not to support  resolutions  other  than  normal  and
2221              fine.  This option has been deprecated by Class1Resolutions.
2222
2223       Class1FrameOverhead
2224              The  number  of extraneous bytes in HDLC frames sent to the host
2225              in response to an ``AT+FRH'' command.  For modems that  properly
2226              implement  the  Class  1 interface, this number should be 4 (the
2227              default).
2228
2229       Class1GreyJPEGSupport
2230              Whether or not to enable support for T.30-E greyscale  facsimile
2231              with  JPEG  compression.  This is always enabled if Class1Color‐
2232              JPEGSupport is enabled.
2233
2234       Class1HookSensitivity
2235              The number of times to  ignore  on-hook  detections  and  merely
2236              treat them as command or modem errors.
2237
2238       Class1JBIGSupport
2239              Whether  or  not to enable support for T.85 monochrome facsimile
2240              with JBIG compression.  Options are ``true'' for support in both
2241              sending  and  receiving,  ``false'' for no support, ``send'' for
2242              support only in sending, and ``receive'' for support only in re‐
2243              ceiving.  If, during the build process a compatible JBIG library
2244              was found then send support is enabled by default.   If,  during
2245              the  build process the TIFF tools are found to support JBIG then
2246              receive support is enabled by default.
2247
2248       Class1MRSupport
2249              Whether or not to enable support  for  two-dimensional  Modified
2250              Read (MR) image data format compression.
2251
2252       Class1MMRSupport
2253              Whether  or  not  to enable support for two-dimensional Modified
2254              Modified Read (MMR) image data format  compression.   Note  that
2255              MMR support requires also ECM support to be enabled.
2256
2257       Class1HasRHConnectBug
2258              A  Class  1 modem should only report CONNECT after AT+FRH=3 when
2259              V.21 HDLC data is detected.  However, some  modems  will  incor‐
2260              rectly  report  CONNECT  after  AT+FRH=3 whenever any carrier is
2261              present. In such cases Class1HasRHConnectBug should  be  set  to
2262              ``true''.
2263
2264       Class1HasRMHookIndication
2265              A  Class  1 modem should result ERROR after AT+FRM=<mod> when it
2266              is on hook.  However, some modems will incorrectly use ERROR re‐
2267              port  a  carrier  detection  mismatch.  In such cases Class1Has‐
2268              RMHookIndication should be set to ``false''.
2269
2270       Class1HFLOCmd
2271              The command to setup hardware (RTS/CTS) flow control between DTE
2272              and DCE when operating in Class 1.  This command is issued imme‐
2273              diately after sending the Class1Cmd to switch the modem to Class
2274              1 operation.
2275
2276       Class1NFLOCmd
2277              The  command  to  setup no flow control between DTE and DCE when
2278              operating in Class 1.  This command is issued immediately  after
2279              sending the Class1Cmd to switch the modem to Class 1 operation.
2280
2281       Class1PageLengthSupport
2282              The  coded  value  for page lengths supported by the modem.  The
2283              only correct values and  meanings  are  these:  ``1'',  A4  page
2284              length; ``3'', both A4 and B4 page length; ``7'', unlimited page
2285              length.
2286
2287       Class1PageWidthSupport
2288              The coded value for page widths supported  by  the  modem.   The
2289              only  correct  values  and  meanings  are  these: ``1'', A4 page
2290              width; ``3'', both A4 and B4 page width; ``7'', all of  A4,  B4,
2291              and A3 page widths.
2292
2293       Class1PPMWaitCmd
2294              The  command  used to stop and wait before sending the post page
2295              message, except before sending  EOP,  when  Class1EOPWaitCmd  is
2296              used  instead.   We  must ensure that the high-speed carrier has
2297              stopped completely.  According to T.30, Chapter 5, Note 4,  this
2298              delay should be 75 +/- 20 ms.
2299
2300       Class1ResponseWaitCmd
2301              The  command used to stop and wait after sending TCF, before at‐
2302              tempting to receive a training response from  the  remote.   Set
2303              this  to  ``AT+FTS=1'' if the modem responds ``OK'' before actu‐
2304              ally dropping the high-speed TCF carrier.
2305
2306       Class1Resolutions
2307              A bitmapped (bit-or'd) value indicating the  resolutions  to  be
2308              supported  during  facsimile  operation.  Individual resolutions
2309              follow Table 21/T.32 and are defined as follows:
2310              Bit              Description
2311              0 (0x00)         R8 x 3.85 l/mm, Normal
2312              1 (0x01)         R8 x 7.7 l/mm, Fine
2313              2 (0x02)         R8 x 15.4 l/mm, Superfine
2314              4 (0x04)         R16 x 15.4 l/mm, Hyperfine
2315              8 (0x08)         200 dpi x 100 l/inch
2316              16 (0x10)        200 dpi x 200 l/inch
2317              32 (0x20)        200 dpi x 400 l/inch
2318              64 (0x40)        300 dpi x 300 l/inch
2319              Thus, a value of 3 would indicate support for normal, fine,  and
2320              superfine resolutions.
2321
2322       Class1RMQueryCmd
2323              The  command  to  send to the modem to get the list of supported
2324              reception bit-rates.  If the parameter begins with a ``!'', then
2325              the  remainder  of  the string is taken to be the modem response
2326              and no command is issued to the modem.
2327
2328       Class1TCFWaitCmd
2329              The command used to stop and wait before sending TCF, similar to
2330              Class1PPMWaitCmd.   According  to  T.30, Chapter 5, Note 3, this
2331              delay should be 75 +/- 20 ms.
2332
2333       Class1TMQueryCmd
2334              The command to send to the modem to get the  list  of  supported
2335              transmission  bit-rates.   If the parameter begins with a ``!'',
2336              then the remainder of the string is taken to be  the  modem  re‐
2337              sponse and no command is issued to the modem.
2338
2339       Class1EOPWaitCmd
2340              The  command  used to stop and wait before sending the post page
2341              message similar to Class1PPMWaitCmd.  We allow a different  set‐
2342              ting  in  the case of EOP, however, because empirically some ma‐
2343              chines may need more time.
2344
2345       Class1ModemHasDLEBug
2346              Used to indicate that the modem does not correctly duplicate DLE
2347              characters in the V.21 communication to the DTE.
2348
2349       Class1MsgRecvHackCmd
2350              If  receive  failures  occur due to +FCERROR just prior to image
2351              data reception, setting  Class1MsgRecvHackCmd  to  AT+FRS=1  may
2352              help.
2353
2354       Class1RecvAbortOK
2355              The  time,  in  milliseconds,  to wait for an ``OK'' result code
2356              from  the  modem  after   aborting   an   HDLC   frame   receive
2357              (``AT+FRH=3'').   If  this number is zero, then the modem is as‐
2358              sumed to not correctly implement aborting and instead the driver
2359              will  wait  200ms,  flush  any input, and then send ``AT\n'' and
2360              wait 500ms for an ``OK'' result.
2361
2362       Class1RecvIdentTimer
2363              The time, in milliseconds, to wait for an initial DCS  when  re‐
2364              ceiving  a  facsimile.  CCITT recommendation T.30 specifies this
2365              as the value of  the  T1  timer.   However,  adaptive  answering
2366              schemes  such  as  that described above under the AdaptiveAnswer
2367              parameter may require that this timer be shortened.
2368
2369       Class1RestrictPoorDestinations¹
2370              The threshold of destination audio quality corruption  at  which
2371              resolution  support should be restricted to ``normal'' and color
2372              support should be disabled.  This  is  intended  to  reduce  the
2373              amount of image data that will be attempted to be sent to a des‐
2374              tination with poor audio quality, thus reducing the  call  dura‐
2375              tion,  and  should  improve the likelihood of successful session
2376              completion.  The threshold is the ratio, expressed as an integer
2377              percentage, of data indicated as corrupt by the destination com‐
2378              pared to total data sent to  the  destination  in  the  previous
2379              three  fax sessions.  Although Class1RestrictPoorDestinations is
2380              functional for destinations with a history of both ECM and  non-
2381              ECM  sessions, the ECM session history is preferred and weighted
2382              considerably higher than non-ECM session history.
2383
2384       Class1RestrictPoorSenders
2385              The threshold of sender audio quality corruption at which  reso‐
2386              lution support should be restricted to ``normal'' and color sup‐
2387              port should be disabled.  This is intended to reduce the  amount
2388              of image data that a sender with poor audio quality will attempt
2389              to transmit, thus reducing the call duration, and should improve
2390              the  likelihood of successful session completion.  The threshold
2391              is the ratio, expressed as an  integer  percentage,  of  corrupt
2392              data  received  compared to total data received from the current
2393              sender in the previous three fax sessions.  Class1RestrictPoorS‐
2394              enders  requires that a CallIDType of ``calling-number'' be con‐
2395              figured in order to match a sender with an  entry  in  the  info
2396              database.
2397
2398       Class1RMPersistence
2399              The  number  of  times that an attempt to receive the high-speed
2400              data carrier should be made, resulting in +FCERROR,  before  the
2401              low-speed  message  carrier reception is attempted.  Some modems
2402              are quick to (perhaps  incorrectly)  return  +FCERROR,  and  for
2403              those  modems a value of 2 or 3 should be used.  For modems that
2404              are not quick to return +FCERROR, a value of 1 should  be  used.
2405              Proper  tuning of this can provide a type of "adaptive reception
2406              control" for modems that accurately return +FCERROR without sup‐
2407              porting  Class1AdaptRecvCmd.   For  those  modems  that  support
2408              Class1AdaptRecvCmd, Class1RMPersistence should probably  not  be
2409              set  at 1, although +FCERROR should almost never occur with such
2410              modems.
2411
2412              If the modem does not support the reporting of +FCERROR or adap‐
2413              tive reception control, then Class1RMPersistence should probably
2414              be set at 0, which causes the timeout looking for the high-speed
2415              data  carrier to be shortened, thus increasing the likelihood of
2416              recovery from any dissynchronization.  When  Class1RMPersistence
2417              is  other  than  0  it is assumed that the +FCERROR reporting or
2418              Class1AdaptRecvCmd is functional and therefore the timeout look‐
2419              ing for the high-speed data carrier is lengthened.
2420
2421       Class1SwitchingCmd
2422              The command used to ensure that the sending facsimile device has
2423              turned off its modulator (i.e. loss-of-carrier)  as  recommended
2424              by T.31: Appendix II.1.
2425
2426       Class1SFLOCmd
2427              The  command  to  setup software (XON/XOFF) flow control between
2428              DTE and DCE when operating in Class 1.  This command  is  issued
2429              immediately  after  sending the Class1Cmd to switch the modem to
2430              Class 1 operation.
2431
2432       Class1SSLFaxCert
2433              The relative path to the PEM certificate file for SSL  Fax  use.
2434              This is normally created by faxsetup(8C).
2435
2436       Class1SSLFaxClientTimeout
2437              The  time,  in milliseconds, that the SSL Fax server should wait
2438              for the client connection to complete before abandoning SSL  Fax
2439              and proceeding with a traditional fax operation.
2440
2441       Class1SSLFaxInfo
2442              The  formatted  hostname  and port number for SSL Fax connection
2443              for this modem.  (Each modem should use a  different  port  num‐
2444              ber.)   This  instructs  the  remote  system  on  how to connect
2445              through the IP network to this system  as  an  SSL  Fax  server.
2446              Firewalling  and  port  forwarding should be carefully addressed
2447              prior to using this configuration.  The format for Class1SSLFax‐
2448              Info  is ``<hostname>:<port>''.  During fax protocol this infor‐
2449              mation will be made into  a  URL  by  prepending  ``ssl://<pass‐
2450              code>@'' and communicated as part of CSA and TSA signals for SSL
2451              Fax.  (``<passcode>'' is a string of random characters.)
2452
2453              ``<hostname>'' may be specified as an IP  address;  however,  in
2454              such   cases  it  should  be  bracketed,  for  example:  ``[<ad‐
2455              dress>]:<port>''.  This prevents confusion, especially with IPv6
2456              addresses.
2457
2458              Either  the  sender or the receiver (or both) must signal an SSL
2459              Fax URL in order for SSL Fax to operate.  If no Class1SSLFaxInfo
2460              is configured for one system, then it is always dependent on the
2461              remote systems to operate as the SSL Fax server.
2462
2463       Class1SSLFaxServerTimeout
2464              The time, in milliseconds, that the SSL Fax client  should  wait
2465              for  the  connection to the server to complete before abandoning
2466              SSL Fax and proceeding with a traditional fax  operation.   Usu‐
2467              ally this must be shorter than 3 seconds.
2468
2469       Class1SSLFaxSupport
2470              Whether or not to enable SSL Fax support.
2471
2472       Class1TCFMaxNonZero
2473              The  maximum  percentage  of non-zero data bytes permitted in an
2474              acceptable received TCF.  Note that this number does not include
2475              any  leading  non-zero  data  in  the  received  data.  See also
2476              Class1TCFMinRun.
2477
2478       Class1TCFMinRun
2479              The duration, in milliseconds, of the minimum run of  zero  data
2480              in  an  acceptable received TCF.  This value should be specified
2481              according to a 1.5 second transmission of  zero  data  (i.e.  it
2482              should be between 0 and 1500).  See also Class1TCFMaxNonZero and
2483              Class1TCFMinRunECMMod.
2484
2485       Class1TCFMinRunECMMod
2486              The factor by which Class1TCFMinRun should be  modified  in  the
2487              case  of an ECM session.  As ECM protocol allows retransmissions
2488              it is commonly faster to accept a lesser-quality data stream and
2489              the  subsequent retransmisisons than it is to allow the communi‐
2490              cation speed to slow down (where the demodulation may still  not
2491              produce an ideal data stream, anyway).
2492
2493       Class1TCFRecvHackCmd
2494              If receive failures occur due to +FCERROR just prior to TCF data
2495              reception, setting Class1TCFRecvHackCmd to AT+FRS=1 may help.
2496
2497       Class1TCFRecvTimeout
2498              The maximum time to wait, in milliseconds, for  the  first  byte
2499              and  again  for the entirety of the Training Check (TCF) message
2500              data that is received during the training phase of the facsimile
2501              reception protocol.
2502
2503       Class1TMConnectDelay
2504              The time, in milliseconds, to delay after receiving CONNECT fol‐
2505              lowing +FTM before sending image data.  T.31 8.3.3 requires  the
2506              modem  to  respond  with  CONNECT before the modulation training
2507              pattern.  If the modem cannot buffer all of the data sent to  it
2508              before successful modulation training then data, especially dur‐
2509              ing TCF (as it is so short), could be lost.  Many modems reason‐
2510              ably  do not follow T.31 in this regard, and thus the default is
2511              zero; however its use with such modems would likely have a  neg‐
2512              ligible  effect.  When modems are used that can buffer data dur‐
2513              ing the training period then the default is also functional.
2514
2515              The modulator training time period varies by modulation and  bi‐
2516              trate.   V.17  fast  train  and V.29 both take less than 400 ms.
2517              However, V.27ter can take twice that long, and V.17  slow  train
2518              can  take  four times as long.  Thus, the early CONNECT stipula‐
2519              tion by T.31 8.3.3 becomes programmatically cumbersome  for  the
2520              DTE.
2521
2522              T.31  8.3.3  requires  the modem to transmit constant ones after
2523              modulator training completes and before the DTE  supplies  data.
2524              Therefore,  some  receivers  have  become  dependent on seeing a
2525              1-to-0 bit transition at the outset of Phase  C  ECM  data,  and
2526              such  an  expectation  for  TCF would also not be surprising (as
2527              both Phase C ECM and TCF involve predictable patterns).   There‐
2528              fore, when not using SSL Fax or SuperG3 V.34-Fax, HylaFAX trans‐
2529              mits a single byte of ones at the outset of both TCF and Phase C
2530              ECM  image data to ensure that there is a 1-to-0 bit transition.
2531              Such does not seem necessary at the outset of  non-ECM  Phase  C
2532              data as the data pattern is not so predictable and any data loss
2533              is likely to go unnoticed.
2534
2535       Class1ValidateV21Frames
2536              Whether or not to use the FCS bits of received V.21 HDLC  frames
2537              to  check the validity of the frame itself.  Most Class 1 modems
2538              perform this check independently (per T.31 7.4) and do  not  re‐
2539              quire this feature to be enabled.
2540

CLASS 2 AND 2.0 MODEM CONFIGURATION PARAMETERS

2542       The  following parameters are specific to the configuration of Class 2-
2543       and Class 2.0-style modems:
2544
2545       Class2Cmd
2546              The command to set the modem into Class 2/2.0 operation.
2547
2548       Class2AbortCmd
2549              The command to use to abort an established session.  After using
2550              this  command  to  abort  a  session, the fax software will send
2551              ModemOnHookCmd and then reset the modem by dropping DTR .
2552
2553       Class2APCmd
2554              A largely unused option for modems  supporting  ITU-T.32,  Class
2555              2.1,  standards.   This  command would be used to enable sending
2556              and receiving SUB, SEP, and PWD frames.
2557
2558       Class2APQueryCmd
2559              A largely unused option for modems  supporting  ITU-T.32,  Class
2560              2.1,  standards.   This command would be used to query the capa‐
2561              bilities of sending and receiving SUB, SEP, and PWD frames.  The
2562              value  ``none''  may  be  used if the modem does not support any
2563              Class2APQueryCmd.
2564
2565       Class2BORCmd
2566              The command to setup the bit order of sent and received  facsim‐
2567              ile  data.   Usually  the  command ``AT+FBOR=0'' is used so that
2568              data is sent and received in direct bit order  (LSB2MSB).   Some
2569              modems,  such  as the Everex 24/96D, must use reversed bit order
2570              for Phase B and D data exchanges to avoid a bug that results  in
2571              garbage  data being placed in the padding of EOL codes.  The bit
2572              order specified by this command must correspond to the  settings
2573              of the ModemSendFillOrder and ModemRecvFillOrder parameters.
2574
2575       Class2BUGCmd
2576              The  command  to  use  to  enable or disable the tracing of HDLC
2577              frames sent and received by the modem.  This tracing information
2578              should be returned to the host in ``+FHR:'' and ``+FHT:'' status
2579              strings.  Note that many Class 2 modems do not support this  fa‐
2580              cility,  which  is  largely  used  for diagnostic purposes.  The
2581              value ``none'' may be used if the modem  does  not  support  any
2582              Class2BUGCmd.
2583
2584       Class2CIGCmd
2585              The  command  used  to set a polling identifier.  This string is
2586              inserted into the format ``%s="<id>"''.
2587
2588       Class2CQCmd
2589              The command to use to set up parameters for copy quality  check‐
2590              ing.   For  example,  for  an Everex 24/96D modem this parameter
2591              might  be  set  to   ``AT+FCQ=1\nAT+FBADMUL=20\nAT+FBADLIN=10''.
2592              Class2CQCmd  should  be  configured to set-up all available copy
2593              quality services available  per  Class2CQQueryCmd.   To  disable
2594              features  that  are available, configure Class2CQQueryCmd with a
2595              ``!'', and then set Class2CQCmd accordingly.
2596
2597       Class2CQQueryCmd
2598              The command to send to the modem to get the copy  quality  capa‐
2599              bilities string.  If the parameter begins with a ``!'', then the
2600              remainder of the string is taken to be the  capabilities  string
2601              and no command is issued to the modem; this can be used together
2602              with the Class2CQCmd to force copy quality checking to  be  done
2603              in  the  server  instead of in the modem.  See also PercentGood‐
2604              Lines and  MaxConsecutiveBadLines  for  parameters  used  to  do
2605              server  copy quality checking.  If copy quality checking is con‐
2606              figured to be done by the modem then  it  is  not  done  by  the
2607              server.
2608
2609       Class2CRCmd
2610              The command to use to enable the reception of facsimile.
2611
2612       Class2DCCCmd
2613              The  command used to set modem capabilities.  This string is in‐
2614              serted into the format ``%s=vr,br,wd,ln,df,ec,bf,st''.
2615
2616       Class2DCCQueryCmd
2617              The command to send to the modem to get the Class 2/2.0 capabil‐
2618              ities.  If the parameter begins with a ``!'', then the remainder
2619              of the string is taken to be the capabilities string and no com‐
2620              mand is issued to the modem.
2621
2622       Class2DDISCmd
2623              The  command  to  set  session  parameters before dialing.  This
2624              string       is       inserted       into       the       format
2625              ``%s=vr,br,wd,ln,df,ec,bf,st''.   Setting this parameter enables
2626              support for Class 2 modems that do not  properly  implement  the
2627              ``AT+FDIS''  command by setting up session parameters before di‐
2628              aling the telephone.
2629
2630       Class2DISCmd
2631              The command used to set the current  session  parameters.   This
2632              string       is       inserted       into       the       format
2633              ``%s=vr,br,wd,ln,df,ec,bf,st''.
2634
2635       Class2ECMType
2636              The interpretation of the EC parameter in the modem DCC response
2637              varies between the Class 2, ``2'', and Class 2.0, ``2.0'', spec‐
2638              ifications.  This configuration parameter allows the administra‐
2639              tor  to specify which type to use.  The corresponding specifica‐
2640              tion type is used by default.
2641
2642       Class2HexNSF
2643              Whether or not to parse the NSF strings reported  by  the  modem
2644              using  hexadecimal values.  By default, they are parsed as hexa‐
2645              decimal values.
2646
2647       Class2HFLOCmd
2648              The command to setup hardware (RTS/CTS) flow control between DTE
2649              and  DCE  when operating in Class 2/2.0.  This command is issued
2650              immediately after sending the Class2Cmd to switch the  modem  to
2651              Class  2/2.0  operation.  For Class 2.0 operation the default is
2652              ``AT+FLO=2''.
2653
2654       Class2JBIGSupport
2655              Whether or not to enable support for T.85  monochrome  facsimile
2656              with JBIG compression.  Options are ``true'' for support in both
2657              sending and receiving, ``false'' for no  support,  ``send''  for
2658              support only in sending, and ``receive'' for support only in re‐
2659              ceiving.  If the modem  supports  JBIG,  and  during  the  build
2660              process a compatible JBIG library was found then send support is
2661              enabled by default.  If the modem supports JBIG, and during  the
2662              build  process the TIFF tools are found to support JBIG then re‐
2663              ceive support is enabled by default.
2664
2665       Class2JPEGSupport
2666              Whether or not to enable and utilize the JPEG support  found  in
2667              the modem.
2668
2669       Class2LIDCmd
2670              The  command  used  to  set  the  local identifier string.  This
2671              string is inserted into the format ``%s="<id>"''
2672
2673       Class2MINSPCmd
2674              The command used to set the minimum acceptable speed to be nego‐
2675              tiated for transmitting page data.  This string is inserted into
2676              the format ``%s=<speed>''
2677
2678       Class2NFLOCmd
2679              The command to setup no flow control between DTE  and  DCE  when
2680              operating  in  Class  2/2.0.  This command is issued immediately
2681              after sending the Class2Cmd to switch the modem to Class 2 oper‐
2682              ation.  For Class 2.0 operation the default is ``AT+FLO=0''.
2683
2684       Class2NRCmd
2685              (Class  2.0  only)  The command to setup negotiation message re‐
2686              porting.  For the correct operation of the Class 2.0 driver this
2687              command  must  enable  the  reporting  of:  receiver parameters,
2688              transmitter parameters, and ID strings.  It is not necessary  to
2689              enable reporting of non-standard frames for correct operation of
2690              the Class 2.0 driver.
2691
2692       Class2PACmd
2693              A largely unused option for modems  supporting  ITU-T.32,  Class
2694              2.1,  standards.   This  command  would  be  used  to set up the
2695              polling address string enabled by the Class2APCmd.
2696
2697       Class2PHCTOCmd
2698              The command to use to set the Phase C timeout parameter (in sec‐
2699              onds).   The  value  ``none''  may be used if the modem does not
2700              support any Class2PHCTOCmd.
2701
2702       Class2PIECmd
2703              (Class 2.0 only) The command to use to control procedure  inter‐
2704              rupt  handling.  Procedure interrupts should be disabled because
2705              HylaFAX does not provide a mechanism for  dispatching  procedure
2706              interrupts to an administrator.
2707
2708       Class2PTSCmd
2709              The  command  to use to set the received page status code.  When
2710              copy quality checking is done in the host, this command  may  be
2711              used  to control the post-page response delivered to the sender.
2712              Beware that some modems do not properly implement  this  command
2713              in  which  case  the  server should be configured to not do copy
2714              quality check: see the PercentGoodLines  and  MaxConsecutiveBad‐
2715              Lines parameters to understand how to defeat copy quality check‐
2716              ing.
2717
2718       Class2PTSQueryCmd
2719              The command to use to query the received page status code.  This
2720              command may be used to determine the post-page response returned
2721              from the receiver.  Beware that some modems do not properly  im‐
2722              plement this command in which case this setting should be set to
2723              ``none''.
2724
2725       Class2PWCmd
2726              A largely unused option for modems  supporting  ITU-T.32,  Class
2727              2.1,  standards.  This command would be used to set up the pass‐
2728              word string enabled by the Class2APCmd.
2729
2730       Class2RecvDataTrigger
2731              The character to send to the modem to trigger  the  transmission
2732              of  received data from the modem to the host.  This character is
2733              specified to be DC1 (octal 21) in the draft specification 2388-A
2734              and  DC2  (octal  22) in the 2388-B specification.  Most Class 2
2735              modems accept DC1 or both DC1 and DC2.  Some modems however only
2736              accept  DC2.  Note that string parameters may use C-style escape
2737              sequences,  so  DC2,  for  example,  would   be   specified   as
2738              ``"\022"''.
2739
2740       Class2RELCmd
2741              The  command  to  use to enable the delivery of byte-aligned EOL
2742              codes in received facsimile.  If this parameter is defined, then
2743              received  facsimile  data  will  be  marked to indicate that EOL
2744              codes are byte-aligned; otherwise they will  be  marked  as  not
2745              (necessarily) having byte-aligned codes.
2746
2747       Class2RTFCC
2748              Whether  or  not to enable MultiTech's Real-Time Fax Compression
2749              Conversion which is available in later  firmware  revisions  for
2750              the  MT5634ZBA-V92,  MT5634ZPX-PCI-V92, and other models.  RTFCC
2751              allows HylaFAX to convert the image compression  between  MH  MR
2752              and MMR formats regardless of how faxq formatted the image file.
2753              If RTFCC is available with your firmware, then the  response  to
2754              ``AT+FFC=?''  is non-zero.  Note that when using RTFCC, the com‐
2755              pression format of the file will be ignored,  thus  the  ``-1'',
2756              ``-2'',  and ``-3'' options for sendfax, ps2fax, and others will
2757              not influence the actual negotiated session parameters.
2758
2759       Class2SACmd
2760              A largely unused option for modems  supporting  ITU-T.32,  Class
2761              2.1, standards.  This command would be used to set up the desti‐
2762              nation subaddress string enabled by the Class2APCmd.
2763
2764       Class2SendRTC
2765              Whether or not to append an explicit ``Return To Control'' (RTC)
2766              signal  to  the  page  data  when transmitting.  The Class 2 and
2767              Class 2.0 specs (i.e. SP-2388-A and TIA/EIA-592) state that  the
2768              modem  will  append  RTC  when it receives the post-page message
2769              command from the host; this parameter is provided  in  case  the
2770              modem does not correctly implement this.
2771
2772       Class2SFLOCmd
2773              The  command  to  setup software (XON/XOFF) flow control between
2774              DTE and DCE when operating in Class 2/2.0.  This command is  is‐
2775              sued immediately after sending the Class2Cmd to switch the modem
2776              to Class 2/2.0 operation.  For Class 2.0 operation  the  default
2777              is ``AT+FLO=1''.
2778
2779       Class2SPLCmd
2780              The  command  to  use  to  enable  a polling request.  The value
2781              ``none''  may  be  used  if  the  modem  does  not  support  any
2782              Class2SPLCmd.
2783
2784       Class2TBCCmd
2785              The  command  to use to enable stream-mode communication between
2786              the host and modem.  The value ``none'' may be used if the modem
2787              does not support any Class2TBCCmd.
2788
2789       Class2UseLineCount
2790              Whether  or not to use the line count reported to HylaFAX by the
2791              modem firmware decoder.
2792
2793       Class2UseHex
2794              Whether or not to parse the capabilities strings reported by the
2795              modem  using hexadecimal values.  By default, they are parsed as
2796              decimal values.
2797
2798       Class2XmitWaitForXON
2799              Whether or not to wait for an XON character from the  modem  be‐
2800              fore sending facsimile data to the modem for transmission.  Note
2801              that this is only relevant for modems that conform to the  Class
2802              2  spec  (i.e.  SP-2388-A).   The Class 2.0 specification states
2803              that the host may transmit data immediately upon receiving  CON‐
2804              NECT and that no XON character will be sent to the host.
2805
2807       The  following  parameters are specific to the configuration and opera‐
2808       tion of the IXO/TAP and UCP support for sending pager messages and  GSM
2809       SM. Parameter not used for UCP are marked with ``(IXO/TAP only)''.
2810
2811       PagerSetupCmds
2812              The  commands to send to a modem to prepare the modem for a call
2813              to pager service provider.  Typically these commands  place  di‐
2814              rect  the  modem to communicate with the service provider at 300
2815              bps using  the  V.21  protocol.   Per-service  provider  command
2816              strings can be setup in the info database; see hylafax-info(5F).
2817
2818       PagerMaxMsgLength
2819              The  maximum  length  for a pager text message.  Messages longer
2820              than this number are truncated.   Per-service  provider  message
2821              lengths can be setup in the info database; see hylafax-info(5F).
2822
2823       IXOService
2824              (IXO/TAP  only) The service identification string transmitted as
2825              part of the IXO/TAP protocol.
2826
2827       IXODeviceID
2828              (IXO/TAP only) The terminal device identification string  trans‐
2829              mitted as part of the IXO/TAP protocol.
2830
2831       IXOMaxUnknown
2832              The  maximum  number  of  unrecognized messages that will be ac‐
2833              cepted at various stages of  the  IXO/TAP  protocol  before  the
2834              sender will abort and hang up the phone.
2835
2836       IXOIDProbe
2837              (IXO/TAP  only)  The  time, in seconds, between sending a ``\r''
2838              during the initial ID recognition sequence of the IXO/TAP proto‐
2839              col.
2840
2841       IXOIDTimeout
2842              (IXO/TAP  only)  The  maximum  time, in seconds, to wait for the
2843              initial ID response from the service provider.
2844
2845       IXOLoginRetries

2855              Ahead message from the service provider.
2856
2857       IXOXmitRetries
2858              The  maximum number of times to try sending a text message block
2859              in a single call.

2869

PROTOTYPE CONFIGURATION FILES

2871       Per-modem  configuration  files  are  typically  derived from prototype
2872       files that have been created for known modems.  These  prototype  files
2873       are kept in the config subdirectory and, by convention, have names that
2874       identify a brand or type of modem and the DTE-DCE flow  control  scheme
2875       the  prototype  files  configures.  The faxaddmodem(8C) program that is
2876       used to configure a modem for use with HylaFAX selects a prototype con‐
2877       figuration file using information retrieved from the modem and comments
2878       embedded in the prototype files.  For Class 1  modems  the  product  ID
2879       code returned by the command ``ATI0'' and the response from the command
2880       ``ATI3'' are used to select a prototype configuration file,  while  for
2881       Class  2  modems the manufacturer and model as returned by ``AT+FMFR?''
2882       and  ``AT+FMDL?'',  respectively,  are   used   (or   ``AT+FMI?''   and
2883       ``AT+FMM?'' for Class 2.0 modems).
2884
2885       A  Class 1 prototype configuration file is identified for use by faxad‐
2886       dmodem by searching for a comment of the form:
2887       # CONFIG:CLASS1:144:.*:RTSCTS: Manufacturer='AT&T' Model=Dataport
2888       In this example ``144'' is the product ID code for an AT&T DataPort mo‐
2889       dem,  ``.*''  is a regular expression matched against the result string
2890       returned by the ``ATI3'' command, and ``RTSCTS'' indicates the modem is
2891       configured  to use hardware flow control during fax operation.  The re‐
2892       mainder of the line is evaluated by the sh(1) and used to  specify  the
2893       modem's  manufacturer and model (since Class 1 modems do not have stan‐
2894       dard commands to query this information).
2895
2896       Class 2 and 2.0 prototype configuration files match the string  ``manu‐
2897       facturer-model-flowcontrol''  against a sh(1) glob pattern specified in
2898       the configuration file, where manufacturer and model  are  the  strings
2899       returned by querying the modem and flowcontrol is either ``RTSCTS'' for
2900       hardware flow control or ``XONXOFF'' for software  flow  control.   For
2901       example:
2902       # CONFIG: CLASS2: ZyXEL*-RTSCTS
2903       # CONFIG: CLASS2.0: USRobotics*-XONXOFF
2904       are  configuration  comments  that  appear  in the prototype file for a
2905       ZyXEL 1496E with Class 2 support, and for a US Robotics  Courier  modem
2906       with Class 2.0 firmware.
2907
2908       The faxaddmodem program merges server-specific configuration parameters
2909       into a prototype configuration according to comments placed in the pro‐
2910       totype  file.   All  lines  between ``BEGIN-SERVER'' and ``END-SERVER''
2911       comments are placed with the appropriate server  configuration  parame‐
2912       ters.  Note that this means modem-related configuration parameters must
2913       be placed outside this area of the file.
