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 monitor
ing 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), adap
tive (adaptive CSLIP/SLIP), ppp (Point-to-Point
Protocol) and kiss (a protocol used for communicat
ing with AX.25 packet radio terminal node con
trollers). 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
[-s speed]
Set a specific line speed, other than the default.
If no arguments are given, the current terminal line (usu
ally: the login device) is used. Otherwise, an attempt is
made to claim the indicated terminal port, lock it, and
open it.
