Hi Rikard!
Sorry... it's Monday...
It is my code. I test for an overrun error and eventually restart the =

receiver.
Another point: you are using the baud rate generator with BRHG =3D 0 and =

SPBRG =3D 2 but this will have a big error...
Try using BRHG =3D 1 and SPBRG =3D 12...

lrx_10                          ;ricezione seriale
        BANKSEL 0
;       btfss   fRXMode
;       goto    lrx_99

;       BANKSEL RCSTA           ;0
        btfsc   RCSTA,OERR
        goto    err_overrun

        btfsc   PIR1,RCIF       ;carattere nel buffer?
        goto    lrx_99

lrx_15                          ;c'=E8 un carattere!
;       BANKSEL RCREG           ;0
        movf    RCREG,w         ;riceve
        movwf   StoreIt
        goto    lrx_99

err_overrun                     ;restart receiver
        bcf     RCSTA,CREN
        bsf     RCSTA,CREN
        clrf    RXCount
        goto    lrx_99

lrx_99
