NAME
slattach, slip -- attach serial lines as network interfaces
SYNOPSIS
slattach [-Hhlmn] [-s baudrate] [-t ldisc] 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 oper- ands are supported by slattach: -H Turn on DTR/CTS flow control. By default, no flow control is done. -h Turn on RTS/CTS flow control. By default, no flow control is done. -l Turn on the CLOCAL flag, making it possible to run SLIP on a cable without modem control signals (e.g. DTR, DSR, DCD). -m Maintain modem control signals after closing the line. Specifically, this disables HUPCL. -n Don't detach from invoking tty. -s baudrate Specifies the speed of the connection. If not specified, the default of 9600 is used. -t ldisc Specifies the line discipline to use for the tty. Sup- ported line disciplines are ``slip'' (creates a sl(4) instance) and ``strip'' (creates a strip(4) instance). If this option is not specified, the default is ``slip''. 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 a SLIP 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 that the specified interface does not exist, the requested address is unknown, or that the user is not privileged but tried to alter an interface's configuration.
