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 oper-
	      ation.  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 indi-
       cated terminal port, lock it, and open it.

NAME

       slattach - Attaches a serial line to a network interface

SYNOPSIS

       /usr/sbin/slattach [{+|-} {c|e|i}] ttyname [baudrate]

DESCRIPTION

       The  slattach  command  assigns	a tty line to a network interface, allowing terminal devices to communicate across a network.  The ttyname
       argument is the name of any valid tty device in /dev.  This can be either the full path name (for example, /dev/tty01) or the name in  /dev
       (for example, tty01).  The optional baudrate argument is used to set the speed of the connection.  The default speed is 9600 baud.

       The  tty  line is attached to the first available network interface (sl0, sl1, already be configured with the local and remote addresses of
       each end of the SLIP connection (see ifconfig(8)).

       Only a person with superuser authority can attach a network interface.

       To detach the interface, use the ifconfig interface_id down command after terminating the slattach process.  interface_id is the name  that
       is shown by the netstat command.

FLAGS

       Enables	(+) or disables (- TCP header compression.  Enables (+) or disables (- automatic TCP header compression. If enabled and the remote
       system is using TCP header compression, TCP header compression is automatically enabled on the local system.  If both local and remote sys-
       tems  have  enabled this flag, TCP header compression is not used. One system must force the use of TCP header compression.  Enables (+) or
       disables (- ICMP traffic suppression. If enabled, ICMP traffic (like that generated by ping(8)) is not allowed to pass over the	SLIP  con-
       nection.

       When  the  system  is  booted, all flags are initially disabled. Once a flag is enabled, it remains enabled until the system is rebooted or
       until another slattach command is issued with the flag disabled.

NOTES

       The slattach command requires the Serial Line Internet Protocol (SLIP), which the kernel must support.  If  making  a  SLIP  connection	to
       another	Tru64  UNIX  system,  both systems must run slattach. If making a SLIP connection to a system not running the Tru64 UNIX operating
       system, the other system must support the SLIP protocol.

EXAMPLES

       To attach a tty device to a network interface, enter: /usr/sbin/slattach /dev/tty01 4800 This command attaches tty01 to a network interface
       to be used by the Serial Line Internet Protocol (SLIP).	The connection speed is 4800 baud.

       To attach a tty device to a network interface at 19200 bits per second (bps), with TCP header compression enabled and ICMP traffic suppres-
       sion disabled, enter: /usr/sbin/slattach +c -i /dev/tty01 19200
