        Specify the baud rate of the serial port. This should be set
        to 250000. Read the FAQ before changing this value.

    help
        Specify the duration of the stepper step pulse time. This
        setting applies to all stepper drivers controlled by the
        micro-controller. If this value is set to zero (or less) then
        the code will "step" and "unstep" in the same C function.

        A setting of zero (or less) on 8-bit AVR micro-controllers
        results in a minimum step pulse time a little over 2us.

        A setting of zero on ARM micro-controllers typically results
        in a minimum step pulse time of 20 cpu cycles.

        The default for AVR is -1, for all other micro-controllers it
        is 2us.
