Serial & Interrupts
I have a question... Some of you may have seen my other post on the DOS board, but this one is more general. I am trying to make a program that works on a DOS touch screen computer. The touch screen is allegedly connected to COM3, using interrupt 15. I think I have read that normally COM3 uses interrupt 3 or 4, so is there anything special that I have to do to specifically use interrupt 15? Also, if it's not to much trouble, can anyone find an example? Anyway, thanks for your help!
There is some fascinating info about programming ports at: www.beyondlogic.org I dunno if it will answer your question.
Corrected above URL. Man, that was embarrasing!
