    PARALLEL PORT MONITOR PROGRAM
        The OPCS software comes with parallel.exe, a program that monitors
        the realtime status of the IBM PC's parallel ports. Run 'parallel.exe'.

    

    USAGE
        parallel [-h] [port|lpt#]

    EXAMPLES
        parallel         - monitor LPT1 (default)
        parallel 1       - monitor LPT1
        parallel 2       - monitor LPT2
        parallel 3       - monitor LPT3
        parallel 378     - monitor parallel port at base address 0378h
        parallel -h[elp] - help screen

    KEYS
        UP/DOWN    - move edit cursor up/down
        ENTER      - toggles state of output (when cursor on an output)
        ESC        - quit program

        While the edit cursor is positioned on an input, the speaker makes
        a 3000 HZ tone if the input is HIGH, and makes no sound if LOW.
