First modem I had was a box with a dial with the options 300/300 orig, 1200/75 orig, 75/1200 ans, 300/300 ans.
It wasn’t acoustically coupled, but it also didn’t dial. I had to pick up the normal phone, dial the BBS, flick the switch to open the line on the modem and put the phone down.
You never experienced the joy of a 1200? You could literally watch the cursor draw the screen.
