Hi, I need to know if it is possible to read 8 bits from the centronics parallel port on an ibm compatible PC. I know it is possible to read 3 bits, and I have even heard it is possible to read 5, but is it possible to read 8 bits, and if it is possible how is it done??

Actually, it is possible to read five bits into the parallel port, but nothing more (I also would like too, and studied a schematics of the circuit). The fact is that the parallel port of the PC has born to drive a printer only. The 25pin connector deserves some 8 pins to GND. It'd have been better to mark 7 of them 'reserved', for future uses like this one. -- ============================================================================== Alessandro Rubini Almo Collegio Borromeo rubini@ipvvis.unipv.it 27100 Pavia, Italy. ==============================================================================
