        ``extgpio,<pin>,<0|1>``

        ``<pin>`` : The IO pin on the PME board, range 0..13 for Digital output.

        ``<0|1>`` : Select 0 for Off (low), and 1 for On (high) level output

        ","
        Switch the pin to either low or high level output.
        "
        "
        ``extpwm,<pin>,<level>``

        ``<pin>`` : The IO pin on the PME board, range 0..7 for Analog output.

        ``<level>`` : The PWM level, range 0..255

        ","
        Set the Analog pin (0..7) to the PWM level, where 0 = 0% and 255 = 100% of the VCC voltage the PME is running at.
        "
        "
        ``extpulse,<pin>,<0|1>,<duration>``

        ``<pin>`` : The IO pin on the PME board, range 0..13 for Digital output.

        ``<0|1>`` : Select 0 for Off (low), and 1 for On (high) level output

        ``<duration>`` : The time in milliseconds the IO pin state should be set, after which it is restored in the previous state.
        ","
        Switch the pin to either low or high level output, and after the duration has passed, return to the previous state.
        "
        "
        ``extlongpulse,<pin>,<0|1>,<duration>``

        ``<pin>`` : The IO pin on the PME board, range 0..13 for Digital output.

        ``<0|1>`` : Select 0 for Off (low), and 1 for On (high) level output

        ``<duration>`` : The time in **seconds** the IO pin state should be set, after which it is restored in the previous state.
        ","
        Switch the pin to either low or high level output, and after the duration (seconds!) has passed, return to the previous state.

        "
        ``status,ext,<pin>``

        ``<pin>`` : The IO pin on the PME board, range 0..13 for Digital output, range 20..27 for the Analog pins A0..A7.
        ","
        Report the current state/value for the pin selected.
