I was assuming it looked like a parallel printer port to the OS. No. A parallel port includes a standard set of handshaking lines, in addition to the (sort of) bidirectional 8-bit data path. The FTDI chips, whether they physically implement a parallel or a serial interface, support only the bidirectional data stream. Therefore, even the 245 is more like a serial port than a parallel port as far as Windows is concerned. -- Dave Tweed -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
