9 x3270 [options] [host]
10 x3270 [options] session-file.x3270
12
15 x3270 opens a telnet connection to an IBM host in an X window. It
16 implements RFCs 2355 (TN3270E), 1576 (TN3270) and 1646 (LU name selec‐
17 tion), and supports IND$FILE file transfer. The window created by
18 x3270 can use its own font for displaying characters, so it is a fairly
19 accurate representation of an IBM 3278 or 3279. It is similar to
20 tn3270(1) except that it is X-based, not curses-based. The full syntax
21 for host is:
22 [prefix:]...[LUname@]hostname[:port][=accept]
23 Prepending a P: onto hostname causes the connection to go through the
25 telnet-passthru service rather than directly to the host. See PASSTHRU
26 below.
27 Prepending an S: onto hostname removes the "extended data stream"
29 option reported to the host. See -tn below for further information.
30 Prepending an N: onto hostname turns off TN3270E support for the ses‐
32 sion.
33 Prepending an L: onto hostname causes x3270 to first create an SSL/TLS
35 tunnel to the host, and then create a TN3270 session inside the tunnel.
36 (This function is supported only if x3270 was built with SSL/TLS sup‐
37 port). Note that TLS-encrypted sessions using the TELNET START-TLS
38 option are negotiated with the host automatically; for these sessions
39 the L: prefix should not be used.
40 Prepending a Y: onto hostname causes x3270 to skip validation of host
42 SSL/TLS certificates. This overrides any other configuration or com‐
43 mand-line options.
44 Prepending an A: onto hostname is equivalent to setting the -nvt
46 option; it forces an NVT-mode session instead of a 3270-mode session.
47 A specific Logical Unit (LU) name to use may be specified by prepending
49 it to the hostname with an `@'. Multiple LU names to try can be sepa‐
50 rated by commas. An empty LU can be placed in the list with an extra
51 comma. (Note that the LU name is used for different purposes by dif‐
52 ferent kinds of hosts. For example, CICS uses the LU name as the Ter‐
53 minal ID.)
54 The hostname may optionally be placed inside square-bracket characters
56 `[' and `]'. This will prevent any colon `:' characters in the host‐
57 name from being interpreted as indicating option prefixes or port num‐
58 bers. This allows numeric IPv6 addresses to be used as hostnames.
59 On systems that support the forkpty library call, the hostname may be
61 replaced with -e and a command string. This will cause x3270 to con‐
62 nect to a local child process, such as a shell.
63 The port to connect to defaults to telnet. This can be overridden with
65 the -port option, or by appending a port to the hostname with a colon
66 `:'. (For compatability with previous versions of x3270 and with
67 tn3270(1), the port may also be specified as a second, separate argu‐
68 ment.)
69 An optional accept name (a hostname to accept in the host's SSL/TLS
71 certificate) may be specified by appending it to the hostname with an
72 equals sign (`='). The accept name can also be specified with the
73 -accepthostname option.
74
77 x3270 is a toolkit based program, so it understands standard Xt options
78 and resources. It also understands the following options:
79 -accepthostname name
81 Specifies a particular hostname to accept when validating the
82 name presented in the server SSL certificate, instead of compar‐
83 ing to the name used to make the connection.
84 -activeicon
86 Specifies that the icon should be a miniature version of the
87 screen image. See ICONS below.
88 -apl Sets up APL mode. This is actually an abbreviation for several
90 options. See APL SUPPORT below.
91 -cadir directory
93 Specifies a directory containing CA (root) certificates to use
94 when verifying a certificate provided by the host. (OpenSSL
95 only)
96 -cafile filename
98 Specifies a PEM-format file containing CA (root) certificates to
99 use when verifying a certificate provided by the host. (OpenSSL
100 only)
101 -cc range:value[,...]
103 Sets character classes.
104 -certfile filename
106 Specifies a file containing a client certificate to provide to
107 the host. The default file type is PEM.
108 -clientcert name
110 Specifies the name of a client certificate to provide to the
111 host. (MacOS only)
112 -certfiletype type
114 Specifies the type of the certificate file specified by -cert‐
115 file. Type can be pem or asn1. (OpenSSL only)
116 -chainfile filename
118 Specifies a certificate chain file in PEM format, containing a
119 certificate to provide to the host, as well as one or more
120 intermediate certificates and the CA certificate used to sign
121 that certificate. If -chainfile is specified, it overrides
122 -certfile. (OpenSSL only)
123 -charset name
125 Specifies an EBCDIC host character set.
126 -clear toggle
128 Sets the initial value of toggle to false.
129 -connecttimeout seconds
131 Specifies the time that x3270 will wait for a host connection to
132 complete.
133 -devname name
135 Specifies a device name (workstation ID) for RFC 4777 support.
136 -efont name
138 Specifies a font for the emulator window.
139 -hostsfile file
141 Uses file as the hosts file, which allows aliases for host names
142 and scripts to be executed at login. See ibm_hosts(1) for
143 details.
144 -httpd [addr:]port
146 Specifies a port and optional address to listen on for HTTP con‐
147 nections. Addr can be specified as `*' to indicate 0.0.0.0; the
148 default is 127.0.0.1. IPv6 numeric addresses must be specified
149 inside of square brackets, e.g., [::1]:4080 to specify the IPv6
150 loopback address and TCP port 4080.
151 Note that this option is mutually-exclusive with the -scriptport
153 option
154 -iconname name
156 Specifies an alternate title for the program icon.
157 -iconx x
159 Specifies the initial x coordinate for the program icon.
160 -icony y
162 Specifies the initial y coordinate for the program icon.
163 -im method
165 Specifies the name of the input method to use for multi-byte
166 input. (Supported only when x3270 is compiled with DBCS sup‐
167 port.)
168 -keyfile filename
170 Specifies a file containing the private key for the certificate
171 file (specified via -certfile or -chainfile). The default file
172 type is PEM. (OpenSSL only)
173 -keyfiletype type
175 Specifies the type of the private key file specified by -key‐
176 file. Type can be pem or asn1. (OpenSSL only)
177 -keypasswd type:value
179 Specifies the password for the private key file (OpenSSL) or
180 client certificate file (MacOS), if it is encrypted. The argu‐
181 ment can be file:filename, specifying that the password is in a
182 file, or string:string, specifying the password on the command-
183 line directly. If the private key file is encrypted and no
184 -keypasswd option is given, the password will be prompted for
185 interactively.
186 -keymap name
188 Specifies a keymap name and optional modifiers. See KEYMAPS
189 below.
190 -keypad
192 Turns on the keypad as soon as x3270 starts.
193 -km name
195 Specifies the local encoding method for multi-byte text. name
196 is an encoding name recognized by the ICU library. (Supported
197 only when x3270 is compiled with DBCS support, and necessary
198 only when x3270 cannot figure it out from the locale.)
199 -loginmacro Action(arg...) ...
201 Specifies a macro to run at login time.
202 -model name
204 The model of 3270 display to be emulated. The model name is in
205 two parts, either of which may be omitted:
206 The first part is the base model, which is either 3278 or 3279.
208 3278 specifies a monochrome (green on black) 3270 display; 3279
209 specifies a color 3270 display.
210 The second part is the model number, which specifies the number
212 of rows and columns. Model 4 is the default.
213 Model Number Columns Rows
215 ──────────────────────────────
216 2 80 24
217 3 80 32
218 4 80 43
219 5 132 27
220 Note: Technically, there is no such 3270 display as a 3279-4 or
222 3279-5, but most hosts seem to work with them anyway.
223 The default model for a color X display is 3279-4. For a
225 monochrome X display, it is 3278-4.
226 -mono Forces x3270 to believe it is running on a monochrome X display.
228 -noverifycert
230 For SSL/TLS connections, do not verify the host certificate.
231 -nvt Start in NVT mode instead of waiting for the host to send data,
233 and make the default terminal type xterm.
234 -once Causes x3270 to exit after a host disconnects. This option has
236 effect only if a hostname is specified on the command line.
237 -oversize colsxrows
239 Makes the screen larger than the default for the chosen model
240 number. This option has effect only in combination with
241 extended data stream support (controlled by the "x3270.extended"
242 resource), and only if the host supports the Query Reply
243 structured field. The number of columns multiplied by the
244 number of rows must not exceed 16383 (3fff hex), the limit of
245 14-bit 3270 buffer addressing.
246 -port n
248 Specifies a different TCP port to connect to. n can be a name
249 from /etc/services like telnet, or a number. This option
250 changes the default port number used for all connections. (The
251 positional parameter affects only the initial connection.)
252 -printerlu luname
254 Causes x3270 to automatically start a pr3287 printer session.
255 If luname is ".", then the printer session will be associated
256 with the interactive terminal session (this requires that the
257 host support TN3270E). Otherwise, the value is used as the
258 explicit LU name to associate with the printer session.
259 -proxy type:host[:port]
261 Causes x3270 to connect via the specified proxy, instead of
262 using a direct connection. The host can be an IP address or
263 hostname. The optional port can be a number or a service name.
264 For a list of supported proxy types, see PROXY below.
265 -pt type
267 Specifies the preedit type for the multi-byte input method.
268 Valid values are OverTheSpot, OffTheSpot, Root and OnTheSpot.
269 The value for OverTheSpot can include an optional suffix, a
270 signed number indicating the vertical distance in rows of the
271 preedit window from the cursor position, e.g. OverTheSpot+1 or
272 OverTheSpot-2. The default value is OverTheSpot+1. (Supported
273 only when x3270 is compiled with DBCS support.)
274 -reconnect
276 Causes x3270 to automatically reconnect to the host if it ever
277 disconnects. This option has effect only if a hostname is
278 specified on the command line.
279 -sb Turns on the scrollbar.
281 +sb Turns the scrollbar off.
283 -scheme name
285 Specifes a color scheme to use in 3279 mode. This option has
286 effect only in combination with 3279 emulation.
287 -script
289 Causes x3270 to read commands from standard input, with the
290 results written to standard output. The protocol for these
291 commands is documented in x3270-script(1).
292 -sl n Specifies that n lines should be saved for scrolling back. The
294 default is 4096.
295 -scriptport [addr:]port
297 Specifies a port and optional address to listen on for scripting
298 connections. Addr can be specified as `*' to indicate 0.0.0.0;
299 the default is 127.0.0.1. IPv6 numeric addresses must be
300 specified inside of square brackets, e.g., [::1]:4081 to specify
301 the IPv6 loopback address and TCP port 4081.
302 Note that this option is mutually-exclusive with the -httpd
304 option
305 -scriptportonce
307 Allows x3270 to accept only one script connection. When that
308 connection is broken, x3270 will exit.
309 -secure
311 Disables run-time features that could compromise system security
312 (user-specified file names and commands, etc.).
313 -set toggle
315 Sets the initial value of toggle to true.
316 -socket
318 Causes the emulator to create a Unix-domain socket when it
319 starts, for use by script processes to send commands to the
320 emulator. The socket is named /tmp/x3sck.pid. The -p option of
321 x3270if causes it to use this socket, instead of pipes specified
322 by environment variables.
323 -tn name
325 Specifies the terminal name to be transmitted over the telnet
326 connection. The default name is IBM-model_name-E, for example,
327 IBM-3279-4-E for a color X display, or IBM-3278-4-E for a
328 monochrome X display.
329 Some hosts are confused by the -E suffix on the terminal name,
331 and will ignore the extra screen area on models 3, 4 and 5.
332 Prepending an s: on the hostname, or setting the
333 "x3270.extended" resource to "false", removes the -E from the
334 terminal name when connecting to such hosts.
335 The name can also be specified with the "x3270.termName"
337 resource.
338 -trace Turns on data stream tracing at startup. Unlike turning it on
340 from a menu option, there is no pop-up to confirm the file name,
341 which defaults to /tmp/x3trc.
342 -tracefile file
344 Specifies a file to save data stream and event traces into. If
345 the name starts with `>>', data will be appended to the file.
346 If the value stdout is given, then traces will be written to
347 standard output. If the value none is given, then traces will
348 be piped directly to the monitor window, and no file will be
349 created.
350 -tracefilesize size
352 Places a limit on the size of a trace file. If this option is
353 not specified, or is specified as 0 or none, the trace file size
354 will be unlimited. The minimum size is 64 Kbytes. The value of
355 size can have a K or M suffix, indicating kilobytes or megabytes
356 respectively. When the trace file reaches the size limit, it
357 will be renamed with a `-' appended and a new file started.
358 -user name
360 Specifies the user name for RFC 4777 support.
361 -v Display the version and build options for x3270 and exit.
363 -verifycert
365 For SSL/TLS connections, verify the host certificate, and do not
366 allow the connection to complete unless it can be validated.
367 (This is the default setting.) This option is overridden by a
368 y: prepended to the hostname when connecting.
369 After reading resource definitions from the X server and any
371 standandard X11 resource definition files ($HOME/.Xdefaults, etc.),
372 x3270 will read definitions from the file $HOME/.x3270pro. This file
373 contains local customizations and is also used to save changed options
374 by the Save Changed Options in File menu option.
375 Note that -xrm options override any definitions in the .x3270pro file.
377
379 The x3270 status line contains a variety of information. From left to
380 right, the fields are:
381 comm status
383 The first symbol is always a 4. If x3270 is in TN3270E mode,
384 the second symbol is a B; otherwise it is an A. If x3270 is
385 disconnected, the third symbol is a question mark. Otherwise,
386 if x3270 is in SSCP-LU mode, the third symbol is an S.
387 Otherwise it is blank.
388 keyboard lock
390 If the keyboard is locked, an "X" symbol and a message field
391 indicate the reason for the keyboard lock.
392 shift Three characters indicate the keyboard modifier status. "M"
394 indicates the Meta key, "A" the Alt key, and an up-arrow or "^"
395 indicates the Shift key.
396 compose
398 The letter "C" indicates that a composite character is in
399 progress. If another symbol follows the "C", it is the first
400 character of the composite.
401 typeahead
403 The letter "T" indicates that one or more keystrokes are in the
404 typeahead buffer.
405 temporary keymap
407 The letter "K" indicates that a temporary keymap is in effect.
408 reverse
410 The letter "R" indicates that the keyboard is in reverse field
411 entry mode.
412 insert mode
414 A thick caret "^" or the letter "I" indicates that the keyboard
415 is in insert mode.
416 printer session
418 The letter "P" indicates that a pr3287 session is active.
419 script The letter "S" indicates that a script is active.
421 LU name
423 The LU name associated with the session, if there is one.
424 timing A clock symbol and a time in seconds indicate the time it took
426 to process the last AID or the time to connect to a host. This
427 display is optional.
428 cursor position
430 The cursor row and column are optionally displayed, zero padded
431 and separated by a "/". Location 001/001 is at the upper left,
432 which is different from the row and columns parameters used with
433 various actions, where the upper left corner is row 0, column 0.
434
436 If the -activeicon option is given (or the "x3270.activeIcon" resource
437 is set to true), x3270 will attempt to make its icon a miniature
438 version of the current screen image. This function is highly dependent
439 on your window manager:
440 mwm The size of the icon is limited by the "Mwm.iconImageMaximum"
442 resource, which defaults to 50x50. The image will be clipped at
443 the bottom and right. The icon cannot accept keyboard input.
444 olwm The full screen image of all 3270 models can be displayed on the
446 icon. However, the icon cannot be resized, so if the model is
447 later changed with an x3270 menu option, the icon image will be
448 corrupted. The icon cannot accept keyboard input.
449 twm and tvtwm
451 The full screen image of all 3270 models can be displayed on the
452 icon, and the icon can be resized. The icon can accept keyboard
453 input.
454 However, twm does not put labels on application-supplied icon
456 windows. You can have x3270 add its own label to the icon by
457 setting the "x3270.labelIcon" resource to true. The default
458 font for icon labels is 8x13; you may change it with the
459 "x3270.iconLabelFont" resource.
460
462 The type of keyboard may be specified with the -keymap switch or using
463 either the KEYMAP or KEYBD environment variables. The types of
464 supported keyboards include sun_k3, sun_k4, sun_k5, hp-k1, hp-pc and
465 ncd.
466 The keymap may also be specified as a comma-separated list of names.
468 Later definitions override earlier ones. This is used to specify both
469 a primary keyboard type and a set of modifiers. The modifiers defined
470 include:
471 ow (OpenWindows) Swaps the middle and right mouse button
473 definitions, so the middle button performs the "Extend" function
474 and the right-hand button performs the "Paste" function. Also
475 changes the cut and paste actions to use the OpenWindows
476 CLIPBOARD.
477 apl Allows entry of APL characters (see APL SUPPORT below).
479 finnish7
481 Replaces the bracket, brace and bar keys with common Finnish
482 characters.
483 norwegian7
485 Replaces the bracket, brace and bar keys with common Norwegian
486 characters.
487 A temporary keymap can also be specified while x3270 is running with
489 the Keymap action. When the action Keymap(n) is executed, temporary
490 keymap n is added to or deleted from the current keymap. Multiple
491 temporary keymaps can be active simultaneously. The action
492 Keymap(None) restores the original keymap. Note: When Keymap() is
493 specified as part of a list of multiple actions in a keymap, it must be
494 the last action in the list.
495 The temporary keymap hebrew is provided to allow entry of Hebrew
497 characters.
498 The X Toolkit translation mechanism is used to provide keyboard
500 emulation. It maps events into actions. The best documentation can be
501 found with X toolkit documents, but the following should suffice for
502 simple customization.
503 An Xt event consists of (at least) four fields. The first is called a
505 modifier. It may be any combination of Meta, Shift and Ctrl. If it is
506 prefaced by !, it means those modifiers only. The second field is the
507 specific event, in x3270 usually just <Key>. The third field is the
508 detail field, which gives the actual key. The name of the key may be
509 determined using the xev program or with the "Trace X Events" menu
510 option. The last field is the action, which is the internal emulator
511 function. A complete list of actions may be found later in the manual.
512 There are three levels of translation tables in x3270. The first is a
514 defined by the resource x3270.keymap.base. It defines alphabetic,
515 numeric, function keys, and such basic functions as Enter and Delete.
516 It allows a minimal useful functionality. It is generally compiled in
517 x3270, but can be overridden.
518 The second level is a keyboard specific table, which is selected by the
520 x3270.keymap resource, and defined by the x3270.keymap.name resource
521 (where name is the value of the x3270.keymap resource). This keymap
522 defines actions for such things as keypad keys, and keys unique to
523 certain keyboards. Several predefined keymaps are included with x3270.
524 The third level is a user customizable table which may be used to
526 augment or override key definitions. This keymap is defined by the
527 x3270.keymap.name.user resource.
528 In addition, keymaps may be defined for use in 3270 mode or NVT mode
530 only. These keymaps use the suffixes .3270 and .nvt in their names,
531 respectively. If a keymap x3270.keymap.name.mode is defined, it will
532 augment the keymap x3270.keymap.name when x3270 is in the given mode.
533 If a keymap x3270.keymap.name.user.mode is defined, it will augment the
534 keymap x3270.keymap.name.user when x3270 is in the given mode.
535 The default translation table x3270.keymap.base is:

640 Meta is the diamond shaped key on a sun_k4, "Alt" on an NCD, "Extend
642 Char" on an HP. The following xmodmap command must be used on the NCD
643 to allow use the the "Alt" key:
644 xmodmap -e "keysym Alt_L = Meta_L"
646 The left mouse button may be used to make a selection. Clicking once
648 unselects the current selection. Clicking twice selects the word under
649 the mouse cursor. Clicking three times selects the line under the
650 mouse cursor. Clicking and dragging selects a rectangular area of the
651 display.
652 The middle mouse button may be used to paste a selection.
654 The right mouse button may also be used for selections, selecting the
656 rectangular area between the current position and where the left button
657 was last pressed.
658 On color X displays, the "x3270.selectBackground" resource is used to
660 distinguish the selected text from the rest of the screen. On
661 monochrome X displays, selected text is in reverse video. (It can be
662 distinguished from a block cursor because the block cursor covers
663 slightly less than an entire character position on the screen.)
664 The left mouse button, when pressed with the "Shift" key held down,
666 moves the 3270 cursor to the where the mouse cursor is pointing.
667 This is the complete list of keymap-callable actions. Other actions
669 are defined for use by scripts and are documented in x3270-script(1);
670 still others are defined for internal use by x3270 and are not
671 documented here. Note that when an action with no parameters is used
672 in a keymap, the parentheses and empty argument list are still
673 required.

785 Note that certain parameters to x3270 actions (such as the names of
787 files and keymaps) are subject to substitutions:
788 The character ~ at the beginning of a string is replaced with the
790 user's home directory. A ~ character followed by a username is
791 replaced with that user's home directory.
792 Environment variables are substituted using the Unix shell convention
794 of $name or ${name}.
795 Two special pseudo-environment variables are supported. ${TIMESTAMP} is
797 replaced with a microsecond-resolution timestamp; ${UNIQUE} is replaced
798 with a string guaranteed to make a unique filename (the process ID
799 optionally followed by a dash and a string of digits). ${UNIQUE} is
800 used to form trace file names.
801
803 The PrintText produces screen snapshots in a number of different forms.
804 The default form wth no arguments sends a copy of the screen to the
805 default printer. A single argument is the command to use to print,
806 e.g., lpr.
807 Multiple arguments can include keywords to control the output of
809 PrintText:
810 file filename
812 Save the output in a file.
813 html Save the output as HTML. This option implies file.
815 rtf Save the output as RichText. This option implies file. The
817 font defaults to Courier New and the point size defaults to 8.
818 These can be overridden by the printTextFont and printTextSize
819 resources, respectively.
820 string Return the output as a string. This can only be used from
822 scripts.
823 modi Render modified fields in italics.
825 caption text
827 Add the specified text as a caption above the output. Within
828 text, the special sequence %T% will be replaced with a
829 timestamp.
830 secure Disables the pop-up dialog.
832 command command
834 Directs the output to a command. This allows one or more of the
835 other keywords to be specified, while still sending the output
836 to the printer.
837
840 There are several types of macros and script functions available.
841 The String Action
843 The simplest method for macros is provided via the String
844 action. The arguments to String are one or more double-quoted
845 strings which are inserted directly as if typed. The C
846 backslash conventions are honored as follows. (Entries marked *
847 mean that after sending the AID code to the host, x3270 will
848 wait for the host to unlock the keyboard before further
849 processing the string.)
850 \b Left
852 \exxxx EBCDIC character in hex
853 \f Clear*
854 \n Enter*
855 \pan PA(n)*
856 \pfnn PF(nn)*
857 \r Newline
858 \t Tab
859 \T BackTab
860 \uxxxx Unicode character in hex
861 \xxxxx Unicode character in hex
862 Note that the numeric values for the \e, \u and \x sequences can
864 be abbreviated to 2 digits. Note also that EBCDIC codes greater
865 than 255 and some Unicode character codes represent DBCS
866 characters, which will work only if x3270 is built with DBCS
867 support and the host allows DBCS input in the current field.
868 An example keymap entry would be:
870 Meta<Key>p: String("probs clearrdr\n")
871 Note: The strings are in ASCII and converted to EBCDIC, so
873 beware of inserting control codes. Also, a backslash before a p
874 may need to be doubled so it will not be removed when a resource
875 file is read.
876 There is also an alternate form of the String action, HexString,
878 which is used to enter non-printing data. The argument to
879 HexString is a string of hexadecimal digits, two per character.
880 A leading 0x or 0X is optional. In 3270 mode, the hexadecimal
881 data represent EBCDIC characters, which are entered into the
882 current field. In NVT mode, the hexadecimal data represent
883 ASCII characters, which are sent directly to the host.
884 The Script Action
886 This action causes x3270 to start a child process which can
887 execute x3270 actions. Standard input and output from the child
888 process are piped back to x3270. The Script action is fully
889 documented in x3270-script(1).
890 The macros Resource
892 An alternate method of defining macros is the "x3270.macros"
893 resource. This resource is similar to a keymap, but instead of
894 defining keyboard mappings, it associates a list of X actions
895 with a name. These names are displayed on a Macros menu that
896 appears when x3270 is connected to a host. Selecting one of the
897 names on the menu executes the X actions associated with it.
898 Typically the actions are String calls, but any action may be
899 specified. Here is a sample macros resource definition, which
900 would result in a four-entry Macros menu:
901 x3270.macros: \
902 log off: String("logout\n")\n\
903 vtam: String("dial vtam\n")\n\
904 pa1: PA(1)\n\
905 alt printer: PrintText("lpr -Plw2")
906 You can also define a different set of macros for each host. If
908 there is a resource named `x3270.macros.somehost', it defines
909 the macros menu for when x3270 is connected to somehost.
910 The -script Option
912 This facility allows x3270 to operate under the complete control
913 of a script. x3270 accepts actions from standard input, and
914 prints results on standard output. The -script option is fully
915 documented in x3270-script(1).
916
918 x3270 allows the direct entry of accented letters and special symbols.
919 Pressing and releasing the "Compose" key, followed by two other keys,
920 causes entry of the symbol combining those two keys. For example,
921 "Compose" followed by the "C" key and the "," (comma) key, enters the
922 "C-cedilla" symbol. A C on the status line indicates a pending
923 composite character.
924 The mappings between these pairs of ordinary keys and the symbols they
926 represent is controlled by the "x3270.composeMap" resource; it gives
927 the name of the map to use. The maps themselves are named
928 "x3270.composeMap.name". The default is "latin1", which gives mappings
929 for most of the symbols in the ISO 8859-1 Latin-1 character set that
930 are not in the 7-bit ASCII character set.
931 Note: The default keymap defines the "Multi_key" keysym as the
933 "Compose" key. If your keyboard lacks such a key, you may set up your
934 own "Compose" key with a keymap that maps some other keysym onto the
935 Compose action.
936
938 x3270 supports the full APL2 character set and the entry of APL
939 characters from the keyboard.
940 APL characters are supported only in the special 3270 font.
942 Keyboard entry of APL characters is supported through the apl keymap
944 modifier. This modifier defines the "Alt" key as an APL shift key,
945 with a typical APL keyboard layout, e.g., "Alt" pressed with the A key
946 results in the APL "alpha" symbol. Overstruck characters such as
947 "quad-quote" are not defined as single keystrokes; instead they are
948 entered as composites (see COMPOSITE CHARACTERS above). A special
949 composite map, apl, is provided for this purpose.
950 Note: Some keyboards do not define the "Alt" key as a modifier, so
952 keymaps that use the "Alt" key will not function. On a Sun for
953 example, this can be remedied with the command:
954 xmodmap -e "add mod2 = Alt_L"
956 For convenience, an -apl option is defined, which is an abbreviation
958 for the following resource definitions:
959 x3270.keymap: your_keymap_name,apl
960 x3270.charset: apl
961 x3270.composeMap: apl
962 There are a number of APL characters that are similar in appearance to
964 non-APL characters. In particular, the APL "stile", "slope," "tilde"
965 and "quotedot" characters are similar to the EBCDIC "bar", "backslash,"
966 "tilde" and "exclaim" characters. The APL characters are entered with
967 the "Alt" key, and have slightly different appearances.
968 The complete list of special APL keysyms is as follows. Entries marked
970 with an asterisk (*) represent simple aliases for standard EBCDIC
971 characters. Entries marked with an (S) represent Sharp APL charatcers.

1106 When compiled with DBCS support, x3270 supports multi-byte input
1107 methods via the XIM protocol.
1108 The input method is selected by the XMODIFIERS environment variable or
1110 the -im command-line option.
1111 The preedit type is specified by the -pt command-line option, with a
1113 default of OverTheSpot+1.
1114
1116 Screen printing is handled through options on the File menu or by the
1117 PrintText and PrintWindow actions. Each results in a pop-up to confirm
1118 the print command.
1119 The PrintText action (usually assigned to the key <Meta>p) sends the
1121 current screen image to the printer as ASCII characters. The default
1122 command used to print the data is controlled by the
1123 "x3270.printTextCommand" resource; the default is lpr. You may also
1124 use a keymap definition to pass a print command the PrintText action
1125 itself. The command receives the screen text as its standard input.
1126 For example, the following keymap will save the screen text in a file:
1127 Meta<Key>f: PrintText("cat >screen.image")
1129 Note: HardPrint is an alias for PrintText.
1131 The PrintWindow action (usually assigned to the key <Meta>b) sends the
1133 current screen image to the printer as a bitmap. The default command
1134 used to print the data is controlled by the "x3270.printWindowCommand"
1135 resource; the default is
1136 xwd -id %d | xpr | lpr.
1138 You may also use a keymap definition to pass a print command to the
1140 PrintWindow action itself. If the command contains the text "%d", the
1141 window ID of x3270 will be substituted before it is run. For example,
1142 the following keymap will pop up a duplicate of the current screen
1143 image:
1144 Meta<Key>g: PrintWindow("xwd -id %d | xwud &")
1146 If the command for PrintWindow or PrintText begins with an "@"
1148 character, the initial pop-up menu to confirm the print command is not
1149 displayed and the command cannot be edited.
1150
1152 Cursor highlighting will not work with if you use the NoTitleFocus
1153 option in your .twmrc file.
1154
1157 x3270 supports the Sun telnet-passthru service provided by the
1158 in.telnet-gw server. This allows outbound telnet connections through a
1159 firewall machine. When a p: is prepended to a hostname, x3270 acts
1160 much like the itelnet(1) command. It contacts the machine named
1161 internet-gateway at the port defined in /etc/services as telnet-
1162 passthru (which defaults to 3514). It then passes the requested
1163 hostname and port to the in.telnet-gw server.
1164
1166 The -proxy option or the x3270.proxy resource causes x3270 to use a
1167 proxy server to connect to the host. The syntax of the option or
1168 resource is:
1169 type:host[:port]
