You havn't given us much to go on Mike....

Is your code getting any characters from the USART ?
Have you got the correct number (zero) of parity bits ?
PIC USART does NOT do parity by itself,  you need to enable the ninth data bit
and work out the parity for yourself.

Maybe you could post the USART code you are using .
