NAME
     ppp - Point-to-Point Protocol network interface

SYNOPSIS
     pseudo-device ppp

DESCRIPTION
     The ppp interface allows serial lines to be used as network interfaces
     using the Point-to-Point Protocol (PPP).

     A ppp interface can be created at runtime using the ifconfig pppN create
     command or by setting up a hostname.if(5) configuration file for
     netstart(8).

     The ppp interface can use various types of compression and has many
     advantages over the SLIP protocol used by the sl(4) interface.

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

HISTORY

BUGS
     Currently, only the ip(4) protocol is supported.
