Ok here is a shorter, well documented, version of the routine that I
posted as "Writing data to a block of addresses using INDF" and it is
still giving me hell. I will not write the data to Rx_Buffer + Rx_Num,
it always write to Rx_Buffer.  =20

RX_INT_HANDLER
        BANK0                           =09
        BTFSS   RCSTA,OERR      ; test if overrun bit is set
        PCALL   RX_1            ; if overrun bit is not set then goto
RX_1
        BCF     RCSTA,CREN      ; if overrun bit is set then stop
continuios receive=20
        BSF     RCSTA,CREN      ;reset error start continuios receive
        MOVF    RCREG,0 ;dummy read
        CLRF    Rx_Num  ;clear Rx_Num
MAD     NOP
        RETURN
RX_1
        BANK0                   ;TEST!!
        MOVLW   Rx_Buffer       ;Move Address of Rx_Buffer to W =09
        ADDWF   Rx_Num, W       ;Add Rx_Num to W                =09
        MOVWF   FSR             ;Place W (Rx_Buffer + Rx_Num) into FSR=09
        MOVF    RCREG,W ;moves RCREG into W             =09
        BCF     STATUS,IRP      ;Clears IRP , Bank0
        MOVWF   INDF            ;copies W into INDF
        INCF    Rx_Num, F       ;Adds 1 to Rx_Num
        MOVF    Rx_Num, W       ;Moves Rx_Num to W
        XORLW   D'16'           ;XOR's W with 16
        BTFSS   STATUS,Z        ;Checks if we are at 16
        GOTO    RX_1            ;If not keep reading
        BSF     Os_Action,RX_CMD;Set RX_CMD to start RX_CMD Routine
        GOTO    MAD             ;Leaves routine

Rx_Num is my pointer for the 16 Byte Bank of addresses that starts with
Rx_Num.  The Bank0 Maacro sets the IRP bit in the STATUS register, but I
put it in the code any way and it is still not writing to the proper
address. So let me know if you spot anything.=20
