vgetty




SYNOPSIS

       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/local/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.


DESCRIPTION

       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 pro­
       vided 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.


OPTIONS

       vgetty accepts the same options as mgetty.  The one's rel­
       evant 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 '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  sin­
              gle quotes (''). Example:

              vgetty -m '"" ATH0 OK'

       -n <rings>


ENVIRONMENT

       vgetty sets the following environment variables when call­
       ing external programs:

       CALLER_ID
              The caller's telephone number.

       CALLED_ID
              The number the caller has dialed. Useful  for  ISDN
              with  multiple  incoming  phone numbers on the same
              physical line.

       CONNECT
              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").


RESOURCES

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

       ftp://alpha.greenie.net/mgetty/source

       The vgetty maintainer's home page is at:

       http://www-internal.alphanet.ch/~schaefer/vgetty.html

       Send problem reports to:

       vgetty-maintainer@alphanet.ch

       For information on mgetty, go to:

       http://alpha.greenie.net/mgetty

       The  mgetty  mailing list is at mgetty@muc.de. The mailing
       list is mirrored to the de.alt.comm.mgetty newsgroup.


FILES

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

       /etc/nologin.ttyXX
              If this file exists, vgetty will not  answer  calls
              on device ttyXX.

       /var/spool/voice/.timestamp
              Used  by  the dtmf.sh script to record last time of
              message playback


DIAGNOSTICS

       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).


BUGS

       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  dis­
       cover  a  bug with how vgetty reacts to your modem, please
       email   the   maintainer   (vgetty-maintainer@alphanet.ch)
       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 operat­
       ing system.
