As is well recorded, UUCP systems swap mail and news (and other files) using (among others) the g protocol. I somehow suspect that when two bitnet sites talk to each other with modems they use something else. Is there any documentation that explains the workings of this protocol. BTW, by it's very nature, this is going to reaching the wrong audience since I'm posting it to a Usenet newsgroup. If there is a bitnet equivalent of comp.mail.misc (maybe handled by a LISTSERV somewhere) where this would be appropriate, I'd be grateful if someone could crosspost.

Due to the origins of BITNET in IBM-to-IBM connectivity solutions, the predominant protocol on BITNET is IBM's proprietary NJE protocol. MVS has native support for this protocol, while sites running the various incarnations of VM use a piece of software called RSCS (remote spooling communications subsystem) to implement the protocol over synchronous leased lines and (via some really nifty software done by Princeton) TCP based networks. 3rd party companies such as Joiner Associates have licensed the protocol from IBM and implemented it for VMS systems. Penn State University and the Hebrew University of Jerusalem have done low-cost implementations of the protocol for VMS and Unix systems. If you want to read the specifications of the protocol, IBM publishes it as something like "Network Job Entry Protocol Specifications and Data Streams" (I don't have the manual handy). Like all IBM publications, it's available from your local IBM sales representative or IBM office. It's a fairly sophisticated protocol, given the hardware restrictions it was designed to deal with. Implementing it is no picnic. > dg@lakart.UUCP - David Goodenough +---+ >AKA: dg%lakart.uucp@xait.xerox.com +---+ -- David Boyes "... no love was left; All Earth was but one thought - and dboyes@rice.edu that was death Immediate and inglorious; and the pang of of famine fed upon all entrails - men Died and their bones were tombless as their flesh ..." - Lord Byron
