I have tried with this code
Code:

---

 
char DATA[4],V3,V4;
void interrupt ISR(void)
{int i;	
//lcd_goto(0x00);
//lcd_string("   INTERRUPT    ");
if(RCIF==1){
	DATA[0]=DATA[1];
	DATA[1]=DATA[2];
	DATA[2]=DATA[3];
	DATA[3]=DATA_IN;
	if(DATA[2]==0x0F){
		if(DATA[3]==0xF0){
			V3=DATA[0];
			V4=DATA[1];}}
}}
