NAME
      getty - set terminal type, modes, speed, and line discipline
 


SYNOPSIS
      /usr/lib/saf/ttymon [ -h ]  [ -t timeout ]  line   [   speed
      [  type  [ linedisc ]  ]  ]
 
      /usr/lib/saf/ttymon -c  file
 


DESCRIPTION
      getty sets terminal type, modes, speed, and line discipline.
      getty  is  a  symbolic  link  to  /usr/lib/saf/ttymon. It is
      included for compatibility with previous releases   for  the
      few applications that still call getty directly.
 
      getty can only be executed by  the  super-user,  (a  process
      with  the  user   ID root). Initially getty prints the login
      prompt, waits for the user's login name,  and  then  invokes
      the login command. getty attempts to adapt the system to the
      terminal speed by using the options and arguments  specified
      on the command line.
 
      Without optional arguments, getty specifies  the  following:
      The   speed of the interface is set to 300 baud, either par-
      ity is allowed, NEWLINE characters are converted to carriage
      return-line  feed,  and  tab  expansion  is performed on the
      standard output. getty types the login prompt before reading
      the  user's  name a character at a time. If a null character
      (or framing error)  is received, it is  assumed  to  be  the
      result  of the user pressing the  BREAK key. This will cause
      getty to attempt the next speed in the  series.  The  series
      that   getty  tries  is  determined  by  what  it  finds  in
      /etc/ttydefs .
 


OPTIONS
      The following options are supported:
 
      -h    If the -h flag is not set, a hangup will be forced  by
            setting  the speed to zero before setting the speed to
            the default or a specified speed.
 
      -t timeout
            Specifies that getty should exit if the  open  on  the
            line  succeeds  and  no one types anything in  timeout
            seconds.
 
      -c file
            The -c option is  no  longer  supported.  Instead  use
            /usr/sbin/sttydefs  -l  to  list  the  contents of the
            /etc/ttydefs file and perform a validity check on  the
            file.

OPERANDS
      The following operands are supported:
 
      line  The name of a  TTY line in  /dev to which getty is  to
            attach itself. getty uses this string as the name of a
            file in the /dev directory to  open  for  reading  and
            writing.
 
      speed The  speed argument is a label to  a  speed  and   TTY
            definition  in  the file /etc/ttydefs. This definition
            tells getty at what speed to run initially,  what  the
            initial  TTY settings are, and what speed to try next,
            (should the user press the  BREAK key to indicate that
            the  speed is inappropriate). The default speed is 300
            baud.
 
      type and linedisc
            These options are obsolete and will be ignored.
