I think the Open DMX USB widget behaves as a raw serial port so you need to
generate DMX packets 'manually' by sending break (sequence of zeros longer
than a character) before each message. At the moment [comport] doesn't have
the capability to send breaks but I think it could be done. Since the
computer has to time the breaks it can happen that they are out of spec and
the DMX equipment doesn't always get the messages. The Pro handles serial
comms with the computer separately from the dmx so the timing is always
