Hi Everyone,

Actually RB1 & RB2 are the hardware pins in a '628 :)

Also check that the USART hasn't detected a farming or overrun error and
stopped receiving.. Can't remember off hand if this shuts down the receiver,
but I have a feeling that it does.

Also, you set the pins to outputs/inputs as required, I can't remember which
what the are supposed to be setup..

Cheers,
Ash.
