Standard AT&T and ISC Unix have ioctl calls KIOCSOUND and KDMKTONE in the
console driver.  They drive the low-fi PC speaker about as well as it can be
driven without doing tricks that take over the whole machine.  You can play
sequences of beeps of various tones.  SCO recognizes the calls but doesn't
actually make any sounds.

Shameless plug:  The Norton Utilities for Unix include, along with all the
useful stuff, a program that plays tones on the speaker, specified either
as frequency and duration or as musical notes.  The new version even has
a speaker kernel driver for SCO.
