[TI-H] Re: port programming
Tons of links to pc hardware info are available at

The parallel port is usually easier to control this way because you can
individually drive every output line. You might be able to use the
control lines on the serial port.
Either way, you need to be able to directly access the io ports, which is
easy if you're using dos, but you need a special driver in windows.
