Question:
(and I hope the answer is yes, 'cause I don't want to do it myself)

Did anyone ever come up with a way to generate multiple tones from
the hp's speaker?  (i.e. phone tones) 

The more I think about it, the more reasonable it sounds.  If the tone 
BEEP generates is a sine wave, there must be a lookup or some call
to generate the waves.  If this could be diverted to another table/function,
multiple tones could be generated by simple addition of two sine waves.

                                              Thanks.
