Hi, Many of the applications that I develop involve reading and writing directly to I/O port. (Usually the parallel port or an I/O card). Since my apps have always ran under Win9x its never been a problem. However, I understand that W2000/NT takes a dim view of accessing IO ports directly and since I can't stop the inevidable advance of W2000 upon my office PC and that of my target PC's, it's only a matter time before it becomes a problem.
Can someone offer any advice, code, net resources, etc on how to tackle direct port IO under NT/2000
