I have problem writing program to control some hardware connected to my parallel or serial port. Under Win 9x it was no problem to write my own ISR to read, write or to
to handle int from these ports using assembler or CreateFile or ... BUT in XP this just not work. I use some drivers (io.dll, zlportio.sys, ...) but These make me only
to read and write. HOW CAN I HANDLE INTERRUPT FROM parallel or serial port UNDER XP or NT???
