Hi i have written small matlab code

Code:

s = serial('COM4','BaudRate',9600);
 fopen(s);
 fprintf(s,'A');

My circuit in proteus View attachment 87800.. IF i send higood. i got this as output in virtual terminal View attachment 87801. And the keil code for receiving data serially is

Code:

#include<reg51.h>
void sertex(unsigned char);
void main(void)
   {							  unsigned char z;
						   TMOD=0x20;
						   TH1=0xFD;
						   SCON=0x50;
						   TR1=1;
				 		  
						   
			while(1)
{

while(RI==0);
z=SBUF;
P1=z;
RI=0;


}
}

. Please someone tell me whats the fault in circuit or in programme.I need to send data from PC and make sure microcontroller received it properly.Thanku
