NAME    [Toc]    [Back]

     slattach - attach serial lines as network interfaces

SYNOPSIS    [Toc]    [Back]

     slattach [-hm] [-s baudrate] ttyname

DESCRIPTION    [Toc]    [Back]

     slattach is used to assign a tty line to  a  network  interface, and will
     attach  the named tty line to the first available slipdevice
that is configured
 and up.  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 properties
 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, automatically
 enable compression of outgoing  packets.

     -link2        Don't auto-enable compression.

     Only the superuser 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    [Toc]    [Back]

           # ifconfig sl0 10.0.0.1 10.0.0.2 link0 link2 up
           # slattach ttyh8
           # ifconfig sl1 192.168.0.1 192.168.0.2 link0 up
           # slattach -s 4800 /dev/tty01

DIAGNOSTICS    [Toc]    [Back]
