[SOLVED] hi i want to recive 5byte data on sbuf of 89c52

hi i want to on /off led when i finsided 5 byte data received on serial port of 89c 52 can any one hav code for it

Run a loop for receiving 5 bytes of data or write a program to receive a byte of data and put it in a loop of 5 and then do the operation you wish to do....

#include<reg51.h>

unsigned char mydata[5];
unsigned char string[5];
unsigned char rd1[5]={"down_"};
unsigned char rd2[5]={"up___"};
unsigned char rd3[5]={"right"};
unsigned char rd4[5]={"left_"};
//unsigned char mydata["right"]=R;
//unsigned char mydata["left_"]=L;




//unsigned char mydata[5];

sbit led_d=P2^0;
sbit led_l=P2^1;
sbit led_r=P2^2;
sbit led_u=P2^3;

void delay(unsigned int value)
{

int i,j;
for(i=0;i<=value;i++)
for(j=0;j<=1275;j++);
}

void main()
{

P2=0xff; //set p2 as o/p


TMOD=0x20; //Enable Timer 1
TH1=0XFD;
SCON=0x50;
TR1=1;

while(1)
{
unsigned int y;//k;


for(y=0;y<5;y++)
{
while(RI==0);
mydata[y]=SBUF;
// delay(1);
P1=mydata[y];
RI=0;
}

//for(k=0;k<5;k++)
{
// if(P1==rd1[k])
if(P1==rd1[5])
{
led_d=~led_d;
}

//else if(P1==rd4[k])
else if(P1==rd4[5])
{

led_l=~led_l;
}
// else if(P1==rd3[k])
else if(P1==rd3[5])
{

led_r=~led_r;

}

// else if(P1==rd2[k])
else if(P1==rd2[5])
{

led_u=~led_u;

}

}
}

}


here my code pls any suggestion i on/off led after five recived data
