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

       [-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 hangup.

       [-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 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.
