vgetty - voice extension to the mgetty+sendfax program
is not meant to be run from the command line. It should be run
from the /etc/inittab file so it can respawn after each call. Here is a
typical inittab entry:
If you already have a line in your inittab file which invokes mgetty,
replace it with vgetty,
since it replaces/extends its functionality.
is an extension to the mgetty+sendfax program which provides an
interface to voice-capable modems. Use it to operate your modem as a simple
answering machine or build your own sophisticated voice messaging system.
handles all the voice-modem specific protocols, giving
application programs a uniform, modem-independent voice library. Supported
modems include many common serial modems from 3com/USRobotics, Elsa,
Multitech, ZyXEL, and others. Caller ID and Distinctive Ring are supported
provided you have subscribed to these services from your phone company.
Software-based modems (winmodems) are not supported.
comes with tools to convert au/wav/voc sound files to/from the
format used by most supported modems. Basic editing and filtering of sound
files is included as well. See pvf(1)
for more information.
accepts the same options as mgetty.
The one's relevant to
voice mode are given here. See mgetty(8)
for other options related to
data and fax modes.
- Use autobauding (change port speed to modem CONNECT speed).
There is no voice modem that needs this, the option is just documented for
- -m 'expect send ...'
- Set the chat sequence that is used to initialize the modem.
For an empty expect part, use empty double quotes (""). Since
the sequence contains spaces, you will have to enclose all of it in single
quotes (''). Example:
vgetty -m '"" ATH0 OK'
- -n <rings>
- Set the number of rings after which vgetty will
answer the phone
- -s <speed>
- Set the serial port speed to use, e.g. "-s
38400". This is the speed of communication between the computer and
modem in bits/sec (baud).
- -x <log level>
- Set the log verbosity level. Zero (0) means no logging, six
(6) is really noisy. Use level six (6) when sending problem reports to the
maintainer. The log file is /var/log/vgetty.ttyXX.
sets the following environment variables when calling external
- The caller's telephone number.
- The number the caller has dialed. Useful for ISDN with
multiple incoming phone numbers on the same physical line.
- The connect string as reported by the modem (e.g.
"38400/V.32bis/V.42bis ... ", etc.).
- The tty device being used (e.g. "ttyS0"). Useful
for handling multiple devices ("messages on this line are for work,
messages on the other line are personal").

supports most standard voice modems, but many modems are not fully
compliant with relevant standards or contain firmware bugs. If you have
problems, try upgrading your modem to the latest firmware revision. If you
discover a bug with how vgetty
reacts to your modem, please email the
maintainer (firstname.lastname@example.org) describing your problem. Include
relevant excerpts from the log file (set log level to six first), and details
about your modem (including firmware revision) and operating system.
