slattach(8)
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
  {+|-}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 flag, 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 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 suppression
  disabled, 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

  Commands: netstat(1), ifconfig(8)

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