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.
