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  speci-
                   fied 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 con-
                   tents 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 read-
                          ing 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.
