MICROSOFT JUNK OS .. USES SOFTWARE DRIVERS TO DEAL WITH HARDWARE .. Even IF THE CPU HAS INSTRUCTIONS TO ACCESS IO PORTS . EXECUTION OF THOSE INSTRUCTIONS (INPORT,OUTPORT)
GENERATE EXECPTIONS (KINDA INTERRUPTS )
SO the only way is HAVE A DRIVER TO DEAL WITH A PORT O MEMORY ..
MICROSOFT HAS A FREE DEV KIT .. YOU CAN DOWNLOAD FROM THEIR WEB SITE ... THAT THING IS BULKY INEFFIECIENT AND POORLY DESIGNED . THERE ARE ALTERNATIVES
ONE IS A PRODUCT FROM A COMPANY CALLED JUNGO THEY OFFER WINDRIVER IS A LAYER ON TOP OF THE DRIVER THAT HIDES ALL THE BORING ASPECTS OF WINDOWS CRAP ..BUT IS EXPENSIVE ..
UNLESS YOU CAN GET IT FOR FREE SOME PLACE I DID ..

THE OTHER WAY IS TO GET A DRIVER ALREADY MADE FOR THAT IO ADRESS , THERE ARE SEVERAL THAT WORK FOR THE PARALLEL PORT AND FOR THE SERIAL PORT . ALSO THEY CAME WITH A LIBRARY THAT YOU CAN CALL
