I found that when I did a try/catch on my code and did the single byte unbuffered reads I was getting framing errors (even though everything is set to 9600 N 8 1) and
when I got some reads to work it did not look like the ASCII format as
documented for the MaxSonar. Maybe it is a unicode thing or maybe
the RoboRIO serial reader is not set up for asynchronous reading like would be needed
for the MaxSonar. Guess I will just have to go with analog.
