slattach(8)
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
       interface:
	    % /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
       interface 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

SEE ALSO
  Commands: netstat(1), ifconfig(8)

  Specifications: SLIP is described in RFC1055.	 TCP header compression is
  described in RFC1144.
