I can only assume that programmers who needed hardware handshaking wrote their own routines. Could someone with a VIC-20 PRG please check to see what the exact word is about CTS? I never did much telecommunicating on the VIC-20, if any at all. I think I may have loaded VIC-Term from cassette once just to watch it work. > Of course the bugs had to be fixed in the 64, since > it uses CIA > instead of VIA, and that is located at a different > place in the > memory map.. Yes, you are probably correct about that. I would assume the VIC-20 bugs were never fixed because telecommunications from personal computers was done mostly at 300 baud. At such a slow speed, I suspect most terminals depended on "X-On/X-Off" protocol for flow control. It was well suited for such slow connections. ===== Get a FREE 6Mb webmail box from go6502! - http://www.geocities.com/profdredd PayPal - The FAST FREE and SECURE way to send money. https://secure.paypal.x.com/refer/pal=profdredd%40yahoo.com __________________________________________________ Do You Yahoo!?
