      Hi:

      The only thing I noticed was that sometimes it would just hang. Pulling the
      plug was the only solution and then it would most likely start fine the next
      time. It got worse once I added a length of cable to the serial port pins.

      I am not in a position to post a photo but I will in about a week.
