I have been trying to read the serial port via SBUF register and dumping its value onto a I/O port. But have been unsuccessful.
I have been using the following test code..... please suggest any modifications if required.


#include<AT89X55.h>

char ch;
void serial_init()
{

SCON = 0x50; /* mode 1, 8-bit uart, enable receiver */

PCON|= 0x80; /* PCON^7 = SMOD doubles the baud rate i.e. k=2 */
TMOD = 0x20; /* timer 1, mode 2, 8-bit reload */
TH1 = 0xFD; /* reload value for 19200 baud */

TR1 = 1;

TI = 1;

}
char receive_byte()
{
RI = 0;
while (RI != 1) {;}

ch=SBUF;
RI = 0;
return ch;

}

void main()
{
serial_init();

P0=receive_byte();
}
