Thanks to Doug's work I was inspired to make the RCX transmit VLL. You just
hook up a light sensor, initialize it, and then use vll_send(code) to
transmit. The little red LED on the light sensor blinks furiously. The Scout
still does this far faster (about 3x) but it probably has some special hardware
(not the least of which is a signaling quality LED). If the RCX goes any
faster the code becomes a blur and the reject rate skyrockets.
After writing the code I spent almost as much time tarting up my web page about
it with graphics:

Feedback welcome, especially from legOS hackers re: my change to dsensor.c to
make this possible
