Arduino BT no work.

Finished the arduino code today, but the computer app froze every time we started it and connected it to the Arduino BT. We determined that this was caused by setting the Baud rate on the serial port to 115200. Therefore we had to switch to the Arduino Diecimilia as it's required Baud rate is 9200, which, for some reason, does not cause the program to freeze up. Will need to look into this.
