SL(4)			 BSD Kernel Interfaces Manual			 SL(4)

NAME
     sl — Serial Line IP (SLIP) network interface

SYNOPSIS
     pseudo-device sl

DESCRIPTION
     The sl interface allows asynchronous serial lines to be used as IPv4 net‐
     work interfaces using the SLIP protocol.

     To use the sl interface, the administrator must first create the inter‐
     face and assign a tty line to it.	The sl interface is created using the
     ifconfig(8) create subcommand, and slattach(8) is used to assign a tty
     line to the interface.  Once the interface is attached, network source
     and destination addresses and other parameters are configured via
     ifconfig(8).

     The sl interface can use Van Jacobson TCP header compression and ICMP
     filtering.	 The following flags to ifconfig(8) control these properties
     of a SLIP link:

     link0	   Turn on Van Jacobson header compression.

     -link0	   Turn off header compression. (default)

     link1	   Don't pass through ICMP packets.

     -link1	   Do pass through ICMP packets. (default)

     link2	   If a packet with a compressed header is received, automati‐
		   cally enable compression of outgoing packets. (default)

     -link2	   Don't auto-enable compression.

DIAGNOSTICS
     sl%d: af%d not supported .	 The interface was handed a message with
     addresses formatted in an unsuitable address family; the packet was
     dropped.

HISTORY
     The sl device appeared in NetBSD 1.0.

BUGS
     SLIP can only transmit IPv4 packets between preconfigured hosts on an
     asynchronous serial link.	It has no provision for address negotiation,
     carriage of additional protocols (e.g.  XNS, AppleTalk, DECNET), and is
     not designed for synchronous serial links.	 This is why SLIP has been
     superseded by the Point-to-Point Protocol (PPP), which does all of those
     things, and much more.
