0:00 Dial Tone(higher (leftmost) values are the receiving modem, lower are sending modem)0:07 "Hello, I am a modem. Are you?""Yes - I am <this type>""Okay then let's use something beyond these basic tones"”sure" 0:11 this tone turnd off echo suppression, which could corrupt data"I'm going to say 6 times what rate and power I can accomplish""Okay, I will say three times what rate I can. And we'll see what match up"0:14"Let's test the line, and switch into full data mode""Sounds good, I will demonstrate a random max data flow to show capacity."The click at the end is the signal to switch to full data mode0:16"I CAN SCREAM THIS LOUD, AND IT SOUNDS LIKE THIS""I CAN SCREAM THIS LOUD MYSELF, AND IT SOUNDS LIKE THIS"(now they can scream together and simultaneously know what eachother sounds like)0:23 that very small spike/click is when you stop hearing it. That's what the click would signalBoth: Authentication complete. Full data floodgates openingBoth: Screaming but they can now understand the other as they scream.What's crazy is the idea behind this. It's all sound communication
Brought back many nice memories of using such devices - thanks!
Lovely. I worked for a company that made modems for end users and also modems for Dell machines.
Great sound I think I have one or two modem cards about still. Working in Electrical Research we tested some of the first modems on a chip early 1970
