hi, i'm using parallel port for simple interfacing. i am able to output data to parallel port. But i'm unable to receive data from the port. I tried making C5 = 1(loaded 20h into 37Ah), but when i read back from the port, i got C5=0 (0C0h back). Unable to change C5 bit. How can i receive data ? I'm using Win2k and the parallel port is in ECP mode. I'm unable to modify ECR register of ECP. I also have userport that enables me to access the ports in win2k.
