This is one of the target applications of the ARMmite. There are
numerous IO boards available for the PC, but not many (if any) are
available for less than $50.

The ARMmite can run a program that takes commands from the PC in
either C or BASIC with getline or DEBUGIN. It would then interpret
that command and do the IO.

From the PC side, any program that can send data to a serial port
(which is what the USB port looks like). This would include Tcl
(which we use), VB, C (examples in the file section of this group),
MatLab (samples in the HelpFiles), Python, Delphi and dozens of others.
