You will enjoy this classic.
It's a lovely image showing the dialup handshake . My first modem was a Hayes 1200 baud. Every modem after seemed to double. The protocols got better too. Bidirectional transfers, wow.
My first modem was a Hayes-brand 300 baud modem. Atari 800 computer.
So I'll kindly ask you to get off my lawn, whipper-snapper.
(BTW I listen to a lot of ambient / noise / drone music, and a while ago, some artist took those modem sounds, slowed them down, put in some reverb, etc. and it was downright ghostly).
The fun things about 300 baud was I could pick up the phone and hear the individual keystrokes being sent. I couldn't distinguish what particular character was being sent, unless of course I was the one typing.
