In the good old DOS days I wrote a little assembly code that could do
that. As I remember, all you need is a proper OUT instruction sent to the
proper port number. But I don't know if "responsible" operating sytems
like Windows (no joke intended) allows applications to perform such
low-level operations. Also, I have no idea how to do this in Matlab.
