/* A simple PHP script using the PHPSerial class to
 * send messages over the serial connection to the arduino
 * from the image map.
 *
 * issues:
 *      - after changing the cycle to 3 from the PSP you cannot change to
 *        any other cycles. (I think the issue is how the PSP interprets
 *        the image map.(IE: try playing with the HTML generating the image
 *        map))

// cycle value to the serial connection
