Bidirectional (input/output) parallel ports are found on many laptops and most if not all IBM PS/2's. Even a unidirectional parallel port has several "printer status" lines that can be used as input. Parallel ports are much faster than serial ports, which is why the external disk drive connects to the parallel port rather than the serial port. -- ========================================================================== Michael A.
