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 terminal ("serial")
       line into one of several "network" modes, thus allowing 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
              communicating 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 useful 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 login device) is  used.
       Otherwise, an attempt is made to claim the indicated terminal port, lock it, and open it.
