NAME
       slattach - attach a network interface to a serial line

SYNOPSIS
       slattach [-dehlLmnqv] [-c command] [-p proto] [-s speed] [tty]

DESCRIPTION
       Slattach is a tiny little program that can be used to put a normal ter-
       minal ("serial") line into one of several "network" modes, thus  allow-
       ing you to use it for point-to-point links to other computers.

OPTIONS
       tty    Path  to a serial device like /dev/ttyS*, /dev/cua* or /dev/ptmx
              to spawn a new pseudo tty.

       [-c command]
              Execute command when the line is hung up. This can  be  used  to
              run scripts or re-establish connections when a link goes down.

       [-d]   Enable  debugging  output.   Useful when determining why a given
              setup doesn't work.

       [-h]   Exit when the carrier is lost. This works on both  /dev/tty  and
              /dev/cua devices by directly monitoring the carrier status every
              15 seconds.

       [-v]   Enable verbose output.  Useful in shell scripts.

       [-q]   Operate in quiet mode - no messages at all.

       [-l]   Create an UUCP-style lockfile for the device in /var/lock.

       [-n]   Equivalent to the "mesg n" command.

       [-m]   Do not initialize the line into 8 bits raw mode.

       [-e]   Exit right after initializing device, instead of waiting for the
              line to hang up.

       [-L]   Enable 3 wire operation. The terminal is moved into CLOCAL mode,
              carrier watching is disabled.

       [-p proto]
              Set a specific kind of protocol to use on the line.  The default
              is  set  to  cslip, i.e. compressed SLIP.  Other possible values
              are slip (normal  SLIP),  adaptive  (adaptive  CSLIP/SLIP),  ppp
              (Point-to-Point Protocol) and kiss (a protocol used for communi-
              cating with AX.25 packet radio terminal node controllers).   The
              special  argument  tty  can  be used to put the device back into
              normal serial operation.  Using 'ppp' mode is not normally  use-
              ful  as  ppp requires an additional ppp daemon pppd to be active
              on the line. For kiss connections the kissattach program  should
              be used.

       [-s speed]
              Set a specific line speed, other than the default.

       If  no arguments are given, the current terminal line (usually: the lo-
       gin device) is used.  Otherwise, an attempt is made to claim the  indi-
       cated terminal port, lock it, and open it.
