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 I had the more luxe version: The 1660! DTMF from the SID! Which meant I could do all the various phreaking boxes in software. So fancy!
@plaidtron3000 Oh yeah I forgot about that. There was a AV breakout cable for it right?
