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 axattach 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.
