Interfacing UART with 8051

The interfacing of serial communication (UART) with 8051 micro controller, with the baud rate of 9600bps.

 Code:

#include <reg51.h>
#include <stdio.h>

unsigned char c;

void Serial_Init()
{
    TMOD = 0x20;
    SCON = 0x50;
    TH1  = 0xFD;
    TR1  = 1;
    TI   = 1;
    RI   = 0;
     
}


void delay(unsigned int i)
{
    unsigned int j,k;
    for(j=0;j<=i;j++)
    {
        for(k=0;k<256;k++);
    }
}

void main(void)
{
    Serial_Init();
    printf("Hello World \n");
    while(1)
    {
       
        delay(5);
        c = getchar();
        delay(5);
        //putchar(c);
        delay(5);       
    }                   
}
