How do you program the sound on an IBM AT or XT?  The technical reference
manual does not help much.  The PLAY and SOUND instructions of BASIC are not
useful in a C program.  (No, I don't want to fork BASICA to make a beep :-)

Would somebody send me the port address and values for different notes, or a
simple C program, or a simple Pascal program, or some other helpful program
which does not rely on library routines to do the real work.  If there is
sufficient interest I will summarize the most useful information to the net.

Thanks,
Fred
