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.
