Assuming you're on some IBM PC-compatible,
simply do a inportb() (reads a byte from hardware port) from the data latch
corresponding to the parallel interface. For example, to get the byte on a
printer port at 0x378, do

	x=inb(0x378);

This is not, in fact, a C question; I've redirected followups to
comp.os.msdos.programmer.

Paul.
