PPP(4)			 BSD Kernel Interfaces Manual			PPP(4)

NAME
     ppp -- point to point protocol network interface

SYNOPSIS
     options PPP_BSDCOMP
     options PPP_DEFLATE
     options PPP_FILTER

     pseudo-device ppp

DESCRIPTION
     The ppp interface allows serial lines to be used as network interfaces
     using the Point-to-Point Protocol (PPP).  The ppp interface can use vari-
     ous types of compression and has many features over the SLIP protocol
     used by the sl(4) interface.

     Supported options are:
     options PPP_BSDCOMP   Enable support for BSD-compress (`bsdcomp') com-
			   pression in ppp.
     options PPP_DEFLATE   Enable support for deflate compression in ppp.
     options PPP_FILTER	   This	option turns on	pcap(3)	based filtering	for
			   ppp connections.  This option is used by pppd(8)
			   which needs to be compiled with PPP_FILTER defined
			   (the	current	default).

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

HISTORY
     The ppp device appeared in	NetBSD 1.0.

BUGS
