Hi,

I'm using the code below to receive a byte from the US ART. When I get the
byte I display it on the LED's and echo it back.
This code is not working for me.  Can anybody tell me what I'm doing wrong.
 Thanks


 list p=16c74
        Title "first aidi Program"

        include <P16C74.INC>

        org     00h

Start
    clrf    PORTB           ;Clear PORT_B output latches

        bsf     STATUS,RP0      ;Go to Bank1

        clrf    TRISB           ;Config PORT_B as all outputs

        movf    RCREG,W         ;Get input data
        movwf   PORTB           ;Display on LEDs
        movwf   TXREG           ;Echo character back
        goto    Start

        end
