uugetty(8)


NAME

  uugetty - Sets the terminal type, modes, speed, and line.


SYNOPSIS

  /usr/lib/uucp/uugetty [-h] [-t  time] [-r] [-c  file] line [speed_label
  [terminal [line_discipline]]]


OPTIONS

  -c file
      Directs that the specified file should be checked instead of the
      /etc/uugettydefs file.

  -h  Holds the carrier during the initialization phase; does not hang up.

  -t time
      Specifies a timeout period for login; in other words, the line is
      dropped if nothing is typed after time seconds.

  -r  Specifies that uugetty should wait for a character before it displays a
      login message, thus preventing two uugetty commands from looping and
      allowing the line to be shared by uucico, cu, and tip.


DESCRIPTION

  The uugetty command sets and manages terminals by setting up speed,
  terminal flags, and the line discipline.  If command options are provided,
  uugetty adapts the system to those specifications; uugetty prints the login
  prompt, waits for the user to enter a username, and invokes the login
  command.

  The uugetty command provides all the features of the getty command, but
  also provides support through the -r option for using the line with the
  uucico, cu, ct, and tip commands.  The line can thereby be used in both
  directions.  The uugetty command enables users to log in, but if the line
  is free, the uucico, cu, ct, and tip commands can be used for dialing out.
  The implementation depends on the fact that the uucico, cu, ct, and tip
  commands create lock files when devices are used.  When uugetty first reads
  characters, the status of the lock file indicates whether the line is being
  used by uucico, cu, ct, or tip, or by someone trying to log in.

  The line argument specifies the /dev/entry file for the terminal line.  It
  can be entered as a relative pathname or an absolute pathname. The
  speed_label argument is a pointer into the /etc/uugettydefs file where the
  definitions for speed and other associated flags are located. If this
  argument is not specified, uugetty uses the first entry in the file.	The
  terminal argument specifies the name of the terminal type. This argument is
  used to set the TERM environment variable for the user who logs in from
  this terminal.  The line_discipline argument specifies the name of the line
  discipline.

  When the -r option is used, the user may have to key several carriage
  returns before the login message is displayed. When uucico attempts to log
  in, the following login script informs it that several carriage returns may
  be necessary before the login message is displayed:

   \r\d\r\d\r\d\r in:--in:login sequence

  In this script, login sequence is whatever is normally used for the login
  sequence.

  An entry for an intelligent modem or direct line that has a uugetty on each
  end must use the -r option.  The following is an /etc/inittab entry using
  uugetty on an intelligent modem or direct line:

  30:2:respawn:/usr/lib/uucp/uugetty -r -t 60 tty12 1200


FILES

  /usr/lib/uucp/uugetty
      Specifies the command path

  /etc/uugettydefs
      The terminal line database file

      This file uses the same format as the/etc/gettydefs file.

  /etc/inittab
      File that specifies the initialization processes

  /var/spool/locks/LCK*
      Lock files used by uugetty, uucico, cu, ct, and tip to keep other
      commands from using the same terminal line
