hi all

plz tell me how to control parallel port by assembly

8 dat pins are OUT controlled

how other status and control pins would be controled also
 

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.

Regards
 

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
 

what to do if i want to send system time to parallel or serial port

how to show total time 00:00--->12:59 or 23:59

i mean bits representing time

pnly data bits r 8 then how to use control pins and status pins
