Has anyone implemented a driver for a BIDIRECTIONAL parallel port? (The standard printer interface is output-only.) I need 8-bit parallel data transfer in both directions but on separate lines with appropriate handshake lines. Data rate will be very slow, under 100 bytes/sec. I'd like to use some low-cost off-the-shelf VMEbus card, such as the Motorola offering. Anybody done this yet? I hate writing drivers. John Nagle (What's on the other end? An IBM Series I driving an IBM 7575 robot. The only I/O supported by the robot software is parallel.)
