What was your first modem? Mine was a 300 baud VICMODEM for my Commodore VIC-20 which included a type in terminal program in the user guide.
You had to manually dial the number with the phone, unplug the coil cable from the handset when you heard the carrier, and plug it into the modem!
@paulrickards 300 baud internal Zoom modem for the Apple II. Didn't even take AT commands!
@scott Oh cool! It probably required special terminal software?
@paulrickards it was built in! You did PR#2 and IN#2 and then hit CTRL-T.
@scott Oh wow that’s great— nearly instant!
