This program causes the PC speaker to generate an audio response to key-
board activity - i.e. a click. there are 10 different clicks available
from 0 to 9. 0 being the highest pitched and 9 being the lowest. there
is a table of frequency's and counts inside the program - debug can be
used to modify this if you'd like. the table occupies 40 bytes (10 entries
of 2 words each) at offset 240 inside the program. the first word is freq
and the second word is duration of click.
The program hooks int 9 and generates a click whenever a key is depressed.
It can only be loaded once per DOS session and will not allow a second
load to occur.
Anyway, that's about all the info necessary to run it and modify it to you
