The CoCo's possess no "sound chip" per se, just about everything's handled by
the CPU.  Therefore, the sound capabilities are limited - especially under OS-9
where cpu-intensive tasks such as sound can't survive along side the operating
system.  Under Basic09, one can get a beep by sending a <cntrl> G to term.
( shell display 7)
Also, one can achieve better effects by using the SS.Tone syscall.  Here you
can specify volume, duration, and pitch.  Check the manual or get back to me
if you need examples.

If you have a Speech/Sound pak you're in luck.  Tandy/MicroWare released both
a driver and descriptor to run the Speech/Sound Pak (S/SP).  All one needs to 
do is redirect standard ASCII text to the descriptor.
( list talk_to_me.txt > /ssp )
It's pretty amazing to see (hear) when you have several things going at once.

Regarding poking sound - this will get you into trouble quick under such a
well-behaved os as OS-9.  Use the setstat calls for sound and the /ssp 
descriptor for speech....

check comp.os.os9 for more details or the listserver at pucc.princeton.edu.
