Since the mouse we used steals the power from RTS( pin 7 of PC serial connector), some changes should be done. Following change is make on UART1 daughter board.
   -  Remove R1.   -  Remove R1.
   -  Connect pin 10 of ADM3202 on ADSP-BF537 UART add-on card to GND.   -  Connect pin 10 of ADM3202 on ADSP-BF537 UART add-on card to GND.
   -  Short pin 7 with pin 8 of ADM3202.  Now there is about 6V power on RTS.   -  Short pin 7 with pin 8 of ADM3202.  Now there is about 6V power on RTS.
   -  Connect the mouse use a cross wire. The serial mouse is connect directly to PC, and the serial port of ADSP-BF537 UART add-on card also connect directly to PC. So we must use a cross wire to connect mouse from ADSP-BF537 UART add-on card.   -  Connect the mouse use a cross wire.

 +<note tip>Don't forget to swith DIP 3 and 4 of SW5 on BF537 stamp board to position ON before you connect the serial mouse.</note>
