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