In MIT/CMU/Harvard PCIP, "most of the TCP/IP protocol and application programs" are handled by code compiled into each application, as I believe somebody pointed out. There is another version of PCIP which is not freely distributable, Stanford's SU-PC/IP, which does have a TSR TCP/IP kernel. There is indeed an interface spec for this 90K TSR, but it is specific to Stanford's SU-PC/IP. While on the subject of SU-PC/IP, I'll point out that it has a decent implementation of MH using POP, which allows secure mail handling on a PC. It also has FTP and the venerable PCIP Telnet, and BOOTP support. We have added a Packet Driver interface, though this is not part of the standard distribution. I'm not sure what the current distribution policy is, but Stanford previously sold academic site licenses for $100. -Ernie (ernie@cwlim.ins.cwru.edu) Standard Disclaimers Apply.
