    Hi,

    I'm using the Microchip PICDEM board to test USART on the 4550 PIC.
    I'm using the default settings and the test code to tx/rx data via
    USART. I can Tx data but Rx doesn't work at all. I've tried all
    routes to get it working - any ideas? Is there any pins I need to set
    up although I've already tested with: RISCbits.TRISC7=1; and
    TRISCbits.TRISC6=0; but still not working on Rx. All Baud rate
    settings, SPBRG/H etc are set up and seem fine... What am i missing to
    get Rx working?????

    Greatly Appreciated!

    GI.
