I used Smartmodem 300’s and 1200’s a lot as a kid dialing up to BBSes in the 80s (also ran a BBS myself). I recall that the modem itself — eg, the AT command interpretation — automatically handled 7E1/8N1/etc., but that’s as far as it went. If I was dialing up a non-8N1 BBS (rare, but they did exist), I had to set my terminal program accordingly. I think I also had to set the speed (although later modems would respond with the speed as an ASCII number in the CONNECT message). Of course, I might be completely misremembering. —John
