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

       [-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.
