And then there was the Commodore 1670, a 300/1200 bps modem with auto-answer. Not only "with" auto-answer; with auto-answer on by DEFAULT, with settings in RAM, and with a computer that you restarted by hitting the power switch. In an era when most people had only one phone line. A critical Commodore skill was the ability to respond to the 1670's answer tone by whistling a 300 baud originator tone, so the 1670 would "detect" carrier, then "detect" carrier drop and hang up the line. So you could talk.
