Whatever else you do, never experiment on your own with ports. One can do real damage to one's system if one doesn't know what one is doing. And even if one does, any mistakes can be fatal. Turbo Pascal books are quite scanty on this subject. Some of the books that I give in the bibliography of my Frequently Asked (Turbo Pascal) Questions take a cursory look at the subject, but that is about all. This has to be a subject for the IBM technical manuals, I would think. ...................................................................
