As a person who had to troubleshoot connections, I even have that first major repeat tone memorized. If it didn’t come through, I knew something was up.
Awful as it sounds, it was still data you could hear and decode using handwritten software. Protocols from those days were ones you could interact directly with - using software like telnet.
HAHAHA! Yeah! I remember that awful noise!
