I learned to make a computer beep using the programmable timer chip (8254?). Send it signals on the I/O port saying "timer chip, speaker signal, counter = N" (where N is the fundamental clock divided by the frequency I wanted), and then "speaker, respond to timer chip". Then you wait the right length of time, then send "speaker, stop responding to timer chip". Of course, I had a bug in the "wait the right length of time" part, and my program stopped running. My family was not amused. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
