:)

So this is essentially morse code generation with the dial turned up into the ultrasonics?

That's it? Okay, cute enough toy I guess.

Hmm, hadn't thought of it that way, but now that you mention it, yes, perhaps! It's still an interesting project that has ramifications elsewhere, like packet networks transmitted over audio, or equivalent. Perhaps it's not that useful, unless you want to annoy the cat. I was glad to hear of those other projects though - minimodem and numpy, since I hadn't heard of them.

I spent the better part of Feb-March playing around with an old Pentium 4 I wanted to turn into a dial-up machine. I got way into the details of serial connections, modems, Getty, ttys, PPP, and the like, and never even really got it working before I finally gave up and admitted defeat. I used a program called minicom for a long while to chat with the modem, and was impressed by just how hard the days of modems and SLIP/PPP connections really were, how much magic really went into negotiating a PPP chat session. Seems like minimodem would be fun to play with too, if only for the change.

If you don't know what "atdp" means I don't want to know you. ;)

I love when that feature is still available on a modem. Actually came in handy once or thrice.

SLIP and PPP are a whole 'nother layer of kludgery of course. The first time I had the Internet actually work over dialup and saw that URLs worked from one site to another I was smiling in amazement. You're right, no one appreciates that enormous underlying complexity.

I wonder what happened to Hayes and USR anyhow.

They seem to be around. A Speedster at 56K can still go for $100 on Amazon.com. I bought a Trendnet for about $30 just to reduce my investment. I still have this nerd dream where we go back to the old days and only the truly neckbearded are prepared ... a fantasy, i know, but I know my Hayes command set just in case the revolution happens ... :)

For the post-apocalyptic future, you should stock-up on low-power computer and ham radio equipment, in a bunker and sufficiently EMP shielded. Shortwave radio would definitely be the fastest and cheapest way to bootstrap regional, national, and international communications systems again.

In the longer term, as long as people are around who remember which technologies worked out and which ones were dead-ends, and which feats were possible and which were never realized, the world would be rebuilt from the dirt, to largely-modern standards, pretty quickly. First farming the most successful crops, then engines and electricity, then information exchange. I

f you're going to lay a wire, you wouldn't resort to dial-up, at least not for long, but would jump up to something faster, like DSL or right to fiber optics.
