For fun and to keep my kernel-hacking hand in, I recently wrote a
character device driver for the console speaker on PC-compatible machines
running UNIX.
The speaker driver permits both absolute time & frequency control (via
ioctls) and control via a `play language' essentially identical to the
PLAY statement feature in IBM BASIC 2.0.
The thing is packaged as an installable device driver kit for SVr3.2;
conversion to XENIX or earlier SV versions shouldn't be hard if you're
so minded. Full documentation and a test set is included.
This driver may be used to put a sound option in the next nethack realease.
Watch for it on a comp.sources.unix near you...
