I posted a question to comp.dcom.modems a while back about this, and got one fellow (who felt sorry for me for having to deal with a vc2100...:-)) I have an aging VC2100 (Volker-Craig terminal emulating a VT102) connected to a nice, new, fancy AX/2400c MNP Class 5 Microcom modem. It's wonderful, 'smarvellous...but it garbages my display something fierce. I am using XON/XOFF (the VC2100 doesn't seem to be able to control RTS/CTS, so hardware flow control is out) to the modem, and have shrunk the MNP 5 packets to 64 bytes max, but the terminal still chokes. The usual symptom is observed in VI: a) cursor is NOT placed where I specified it go; b) characters in the line get clobbered (in the vicinity of the proper position); c) on a "tab" or autoindent, the cursor is NOT at the specified tab position (usually left by about one char pos) Redisplaying the screen SOMETIMES clears up the problem (about 50%), depending on the severity of the screwup. THe text is fine, verified by checking by other means (cat, more, etc). It's just the cursor positioning that's screwy. This terminal has served me well before, at up to 9600 bit/s, and on occasion seen service at 19.2k. Never a problem until now. Could it be the terminal finally giving up the ghost? I hope not, as I'm not really sufficiently flush to buy a replacement...but it's wreaking hell on trying to get any work done from home. Note that I have hacked the termcap I'm using from the VT102 termcap (extending various of the delay times). One option which springs immediately to mind is: if anyone has a good termcap for this terminal, could you ship it this way? Thanks for any help you can give.
