It'd be a good idea to print all exceptions, it can help debugging the
problem (if you don't like it going to the screen of an end user at
least write it to a log file):

except SerialException, err:
    print err
    print ">>>>>Timed out<<<<<"

except OSError, err:
    print err
    print "Serial port failure.  Power cycle units"

and in your OpenPort function too.
