       vgetty - voice extension to the mgetty+sendfax program


       vgetty [options] ttydevice

       vgetty  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:

       S0:345:respawn:/usr/sbin/vgetty ttyS0

       If  you  already have a line in your inittab file which invokes mgetty,
       replace it with vgetty, since it replaces/extends its functionality.


       vgetty 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.    vgetty  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.

       vgetty  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.


       vgetty 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.

       -a     Use  autobauding  (change  port  speed  to modem CONNECT speed).
              There is no voice modem that needs  this,  the  option  is  just
              documented for completeness.

       -m â€â€™expect send ...â€â€™
              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.


       vgetty  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.).

       DEVICE 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").


       vgetty is included in the mgetty+sendfax distribution. For  the  latest
       release, go to:

              Main configuration file for vgetty.  Many options here  override
              the equivalents found in /etc/mgetty+sendfax/mgetty.config

              Used  by  the  script  to  record  last time of message


       If vgetty doesn’t work they way you think  it  should,  check  the  log
       file.   By  default,  it  is  located in /var/log/vgetty.ttyXX (for the
       vgetty process handling device ttyXX, e.g. ttyS0).


       vgetty 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 (  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.
