[net.micro.pc] toggling IBM-PC pins

kevin@fluke.UUCP (Kevin Coffinger) (09/12/85)

	I am trying to change the voltage high and low on the cassette port
and the serial port on my IBM-PC.  I need some info on how to do this from
a program in either BASIC or assembly language.  If any of you hackers out
there have suggestions on how to do this, please drop me a line.

						Thanks
