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.
FILES
