This is a simple Assembler program to write into a Parallel port. In this case the parallel port Address is 0x378. Check in your PC bios or in windows/system to see if your LPT port (parallel port) address match.

**broken link removed**

There are many Assembler for x86 computers out there. Just search in google.

assume ur port address is 378 hex. then u can write:

mov AH,378
mov AL,-----data u want to send to LPT port ----
out AH,AL
