That's odd. It looks like the read from the dmxfd file descriptor is 
failing in the line

buffer.extend(dmxfd.read(3))

I don't understand why. This should simply read three bytes and put them 
in the buffer. It is an I/O error so maybe the dmxfd file descriptor is 
not opened properly and the code is attempting to read 3 bytes from an 
object which is less than 3 bytes in size? Maybe insert a "print 
sys.getsizeof(dmxfd)" statement to see what size it is?
