Hello boydtvt32,

My apology for waiting the answer.
For problem that you have, you must to clear registers UDR0 and UDR1:
UDR0 = 0;
UDR1 = 0;

First refer to UART1 and the second one are refer to UART2.

You can see more information about this microcontrollers and his registers on this site:

Best regards,
Veljko Pavlovic.
