This - * all needs tidying up in future but it does actually work for point - * to point communications. I have an SDL WANic400 synchronous - * communications card that comes with Windows NT drivers. The drivers - * support a mode that they call "Ethernet Emulation". That simply - * puts the IP frame in an HDLC frame without any ethernet header. i.e. - * . There is no addressing beyond - * the IP header information so is only suitable for point to point links - * with a single protocol. "At some point" I will add a Frame Relay header - * but at the moment I have difficulties getting the WANic card driver's - * Frame Relay driver to work. - * - * Copyright (c) 1982, 1989, 1993 - * The Regents of the University of California.
