SLATTACH(8)                 System Manager's Manual                SLATTACH(8)

NAME
     slattach - attach serial lines as network interfaces

SYNOPSIS
     slattach [-hm] [-s baudrate] ttyname

DESCRIPTION
     Slattach is used to assign a tty line to a network interface, and to
     define the network source and destination addresses.  The following
     operands are supported by slattach:

     -h            Turn on RTS/CTS flow control.  By default, no flow control
                   is done.

     -m            Maintain modem control signals after closing the line.
                   Specifically, this disables HUPCL.

     -s baudrate   Specifies the speed of the connection.  If not specified,
                   the default of 9600 is used.

     ttyname       Specifies the name of the tty device.  Ttyname should be a
                   string of the form `ttyXX', or `/dev/ttyXX'.

     In addition, the following flags to ifconfig(8) control various proper-
     ties of the link:

     link0         Turn on Van Jacobsen header compression.

     -link0        Turn off header compression.

     link1         Don't pass through ICMP packets.

     -link1        Do pass through ICMP packets.

     link2         If a packet with a compressed header is received, automati-
                   cally enable compression of outgoing packets.

     -link2        Don't auto-enable compression.

     Only the super-user may attach a network interface.

     To detach the interface, use ``ifconfig interface-name down'' after
     killing off the slattach process.  Interface-name is the name that is
     shown by netstat(1).

EXAMPLES
           slattach ttyh8
           slattach -s 4800 /dev/tty01

DIAGNOSTICS
     Messages indicating the specified interface does not exit, the requested
     address is unknown, the user is not privileged and tried to alter an
     interface's configuration.
