Well, I have the source code to a commercial-grade telnet client that DOES work properly with BSDI... so I'll see what I can figure out with that first. >IME, BSDI's networking code is quite good, and about as standard compliant >as you will find.

Agreed... I'll be the first to admit that I have no clue what I'm doing when it comes to low-level networking programming... And this is my first attempt at writing any sort of TCP/IP application. So... I'll be the first to say that the problem is probably not with BSDI. :-) I'm just trying to figure out what parameter that BSDI doesn't like enough to make it drop the session in mid-session. {shrug} Well I'm going to play with it a little more today, and if I really can't figure it out, I might put it on the shelf for awhile so I can get some other stuff done, and just let people know about the tset workaround. But I'll keep plugging away at it for now. It's just very frustrating for me... Not that it doesn't work, but because I don't know the telnet protocol inside-out and backwards like I do databases and some other things. :-) >In fact, it now seems likely that problem people had connecting to BSDI >systems had nothing to do with telnet in the first place.

At least I know there is some sort of workaround until I get this negotiation thing working right on BSDI machines. (There is actually one company that is telnetting into a FreeBSD machine, and then opening a telnet session from that shell to their BSDI box... ugly but it worked I guess.) hehe - Shawn ------------------------------- Shawn D.
