       slattach - attach a network interface to a serial line


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


       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.


       [-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.
