NAME

  slattach - Attaches a	serial line to a network interface

SYNOPSIS

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

OPTIONS

  {+|-}c
      Enables (+) or disables (-) TCP header compression.

  {+|-}e
      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 systems have enabled this option, TCP header
      compression is not used. One system must force the use of	TCP header
      compression.

  {+|-}i
      Enables (+) or disables (-) ICMP traffic suppression. If enabled,	ICMP
      traffic (like that generated by ping(8)) is not allowed to pass over
      the SLIP connection.

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

OPERANDS

  ttyname
      The name of any valid tty	device in /dev.	You can	use either the full
      pathname such as /dev/tty01 or the name in /dev such as tty01. This
      operand is mandatory.

  baudrate
      Specifies	the connection speed, for example: 9600. This operand is
      optional.

DESCRIPTION

  The slattach command assigns a tty line to a network interface, allowing
  terminal devices to communicate across a network.

  The tty line is attached to the first	available network interface (sl0,
  sl1, ...).  Before issuing the slattach command, the network interface must
  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.




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

   1.  Use the following command to attach a tty device	to a network inter-
       face:
	    % /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.

   2.  Use the following command to attach a tty device	to a network inter-
       face at 19200 bits per second (bps) with	TCP header,:enter:
	    % /usr/sbin/slattach +c -i /dev/tty01 19200



FILES

  /usr/sbin/slattach
      Specifies	the command path

  /var/run/ttyxx.pid
      Contains the slattach process ID
