10 vgetty [options] ttydevice
11 vgetty is not meant to be run from the command line. It should be run
13 from the /etc/inittab file so it can respawn after each call. Here is a
14 typical inittab entry:
15 S0:345:respawn:/usr/local/sbin/vgetty ttyS0
17 If you already have a line in your inittab file which invokes mgetty,
19 replace it with vgetty, since it replaces/extends its functionality.
20
22 vgetty is an extension to the mgetty+sendfax program which provides an
23 interface to voice-capable modems. Use it to operate your modem as a
24 simple answering machine or build your own sophisticated voice messag‐
25 ing system. vgetty handles all the voice-modem specific protocols,
26 giving application programs a uniform, modem-independent voice library.
27 Supported modems include many common serial modems from
28 3com/USRobotics, Elsa, Multitech, ZyXEL, and others. Caller ID and
29 Distinctive Ring are supported provided you have subscribed to these
30 services from your phone company. Software-based modems (winmodems)
31 are not supported.
32 vgetty comes with tools to convert au/wav/voc sound files to/from the
34 format used by most supported modems. Basic editing and filtering of
35 sound files is included as well. See pvf(1) for more information.
36
38 vgetty accepts the same options as mgetty. The one's relevant to voice
39 mode are given here. See mgetty(8) for other options related to data
40 and fax modes.
41 -a Use autobauding (change port speed to modem CONNECT speed).
43 There is no voice modem that needs this, the option is just doc‐
44 umented for completeness.
45 -m 'expect send ...'
47 Set the chat sequence that is used to initialize the modem. For
48 an empty expect part, use empty double quotes (""). Since the
49 sequence contains spaces, you will have to enclose all of it in
50 single quotes (''). Example:
51 vgetty -m '"" ATH0 OK'
53 -n <rings>
55 Set the number of rings after which vgetty will answer the phone
56 -s <speed>
58 Set the serial port speed to use, e.g. "-s 38400". This is the
59 speed of communication between the computer and modem in
60 bits/sec (baud).
61 -x <log level>
63 Set the log verbosity level. Zero (0) means no logging, six (6)
64 is really noisy. Use level six (6) when sending problem reports
65 to the maintainer. The log file is /var/log/vgetty.ttyXX.
66
68 vgetty sets the following environment variables when calling external
69 programs:
70 CALLER_ID
72 The caller's telephone number.
73 CALLED_ID
75 The number the caller has dialed. Useful for ISDN with multiple
76 incoming phone numbers on the same physical line.
77 CONNECT
79 The connect string as reported by the modem (e.g.
80 "38400/V.32bis/V.42bis ... ", etc.).
81 DEVICE The tty device being used (e.g. "ttyS0"). Useful for handling
83 multiple devices ("messages on this line are for work, messages
84 on the other line are personal").
85
87 vgetty is included in the mgetty+sendfax distribution. For the latest
88 release, go to:

103 The mgetty mailing list is at mgetty@muc.de. The mailing list is mir‐
105 rored to the de.alt.comm.mgetty newsgroup.
106
108 /etc/mgetty+sendfax/voice.conf
109 Main configuration file for vgetty. Many options here override
110 the equivalents found in /etc/mgetty+sendfax/mgetty.config
111 /etc/nologin.ttyXX
113 If this file exists, vgetty will not answer calls on device
114 ttyXX.
115 /var/log/vgetty.ttyXX
117 Debug log file for vgetty.
118 /var/spool/voice/messages/Index
120 List of greeting messages to use.
121 /var/spool/voice/.code
123 Access code for remote playback of messages using the dtmf.sh
124 script
125 /var/spool/voice/.flag
127 vgetty touches this file when a new message is received
128 /var/spool/voice/.timestamp
130 Used by the dtmf.sh script to record last time of message play‐
131 back
132
135 If vgetty doesn't work they way you think it should, check the log
136 file. By default, it is located in /var/log/vgetty.ttyXX (for the
137 vgetty process handling device ttyXX, e.g. ttyS0).
138
140 vgetty supports most standard voice modems, but many modems are not
141 fully compliant with relevant standards or contain firmware bugs. If
142 you have problems, try upgrading your modem to the latest firmware
143 revision. If you discover a bug with how vgetty reacts to your modem,
144 please email the maintainer (vgetty-maintainer@alphanet.ch) describing
145 your problem. Include relevant excerpts from the log file (set log
146 level to six first), and details about your modem (including firmware
147 revision) and operating system.
