You can use outport/inport but you have to know how to "program"
the UART (which is convered in many "Inside the PC" books).

You might find portopen/portclose/portreadchar/portwritechar easier
to work with. Where you can just write or read bytes to COMn:

However someone just reported a bug on portreadchar in the Win32
flavor which I have fixed in 6.2c but have not released yet (I will
soon). Meanwhile you can test things out using the 16bit version.

You might also check out MMLogic (see same web site as MSWLogo)
which lives and breathes real time control. You could probably
do the whole project in it :-)
