<title>Introduction</title>
<para>
The syncppp drivers in Linux provide a fairly complete
implementation of Cisco HDLC and a minimal implementation of
PPP. The longer term goal is to switch the PPP layer to the
generic PPP interface that is new in Linux 2.3.x. The API should
remain unchanged when this is done, but support will then be
available for IPX, compression and other PPP features

The current PPP implementation is very basic, although sufficient
for most wan usages.

<para>
Currently we do not end all packets with the correct Cisco multicast
or unicast flags. Nothing appears to mind too much but this should
be corrected.
