Hello, If my understanding of PCIP is correct, PCIP has some sort of TSR (or device driver), that handles most of the TCP/IP protocol and application programs (like Telenet FTP, etc) interface with that driver. (thus the driver is shared, unlike programs like NCSA telnet). Now a while back, I heard that there was a spec for interfacing to the PCIP driver. I am looking for this spec. Any pointers would be appreciated. Thanks Vance Morrison Univ of Il.

PC/IP had no TSR driver. Its TCP and other protocols could be linked into any small memory model application, but that application then had to contend with the tasking package. PC/IP's spiritual successor, FTP Software's PC/TCP, does have a TSR kernel with TCP and other basic network protocols available through a software interrupt interface. That interface is non-proprietary, and is documented in the developer's kit. I believe that Wollongong's WIN/PC should have some kind of TSR interface, and that the UMD code does, but I don't know any details about these. - john romkey USENET/UUCP: romkey@asylum.sf.ca.us Internet: romkey@ftp.com "There is no loyalty except loyalty to the party.

You mean MIT/CMU/Harvard's PCIP. FTP to ftp.com, and look around.
It's called packet_d.txt.

It sounds like you're thinking of our PC/TCP product, which is a commercial DOS TCP/IP developed from a PCIP base. PCIP itself has the protocol stack linked into the application, and no part of it is a TSR. Our versions up to 1.16 worked the same way, but then we did v2.0, which put the stack into a TSR module, and had the applications talking to it via INT instructions. James B.

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.
