Ok,
First, get a box. Than get a cable running from the back of your computer port into the box. Put duct tape around the whole thing, with the roll in the box, and if you programming is correct, it should humm and get warm to the touch. If it goes up in flames, or does nothing, your programming is incorrect.
Ok, ok, for real. I would like to help. I know a "skimming" ammount of pbasic, and would like to know how i can get a hold of some C, C++, and Linux programs, for free and small (i am on a 56k modem), so i can learn and help out w/ this program if it goes through!
