Don: It's refreshing to see somebody that knows what the terms really mean! Am I correct that a Bell212A modem (or that standard if you like) is only 300 baud/1200bps? A long time ago (well, about 12 years ago) I helped a friend who was customizing the MODEM program (for CP/M) to handle Bell202C modems (1200 baud OR bps half duplex). This was back in the time when a high speed modem (1200bps) was a rarity, and very expensive (if you could even buy one), and we had a pair that we paid $800.00 for (212A's that is). We were doing the work for half duplex, as there were many 202's available at flea markets in the $10.00-$20.00 range. I believe that the 202's are still used by ham operators, as they're about the only modems that have only one carrier tone, only on when sending, quiet when recieving. It's truly amazing the advances that have been made over the last few years, now I have a 9600bps modem that is starting to be considered slow (it can't go higher than 9600!), back 12 years ago, 300 was the norm, and my 'letter quality printer' was a Teletype ASR33 running at the blazing speed of 110 baud! What little programming I still remember (not much) was learned in a HS computer science class that used a PDP11/70 with TTYs as terminals, and PAPER TAPE as the storage media (for students at least). I remember taking those tapes home, and loading them into my NorthStar thru the TTY I had at home, talk about a program taking a long time to load! Sorry for rambling, your message just sort of made me remember to old days (I'm not too sure how 'good' they were) -Mike Schiller In sunny Fort Lauderdale
