With windows XP, normal inport, outport functions do not seem to work. I downloaded a utility to open ports and then use these funtions, but it didnt help. Anyone can give details how to do parallel port programming in XP using C?

inport() and outport() functions do work if you have opened the port. I use a software called Userport to do the same. Alternatively you could try inportb() and outportb(). Here is a tutorial on parallel port programming in C
