UNGETTY(M)               XENIX System V                UNGETTY(M)



     Name
          ungetty - Suspends/restarts a getty process.

     Syntax
          ungetty [-r, -t] line

     Description
          ungetty is used to suspend and restart a getty process on a
          serial line that has been set up as a dial-in/dial-out port.
          dial(M) invokes ungetty to toggle the port from dial-in to
          dial-out. (See /usr/lib/uucp/dial.c for a sample program
          which uses ungetty.)

          When ungetty is run on a serial line, it checks to see if
          the line is listed in /usr/lib/uucp/L-devices. If so, it
          suspends the getty process on that line.

          ungetty has the following options:

          -r   Restart a disabled line.

          -t   Test a line to see if it is enabled.

          ungetty returns the following values when it is called with
          no options:

          0    The line is not enabled.

          1    Successful. The getty on that line is suspended.

          2    Could not suspend the getty. This means that the line
               is being used by another program.

          ungetty returns the following values when used with the -t
          and -r options:

          0    -r or -t:
               Line not enabled.

          1    -r:
               Successfully restarted.

               -t:
               Line needs restarting.

          2    -r or -t:
               Cannot restart getty.
