Well, i found a part here:

Code:
;                    Display Watts on LCD
;
Show_Watts:
	mov16	Watts,Number
	call	bin2dec
	call	ShowDec1	; display "xxxx.x"
	movlw	'W'
	call	Print_Char	; display 'W'
	movlw	' '
	call	Print_Char
	return

;--------------------------------------------------------------------
If this is the case, can i add UART routine here so that i can set the baud rate over the RF input?
