Difference in Output of Simulator and Emulator

#include <reg51.H>
void SerTx(unsigned char);

void main(void)
{

        int counter;
        TMOD = 0x20;
        TL1=0xFD;
        TH1 = 0xFD;
        SCON = 0x50;

        TR1 =1;
        for(counter=0;counter<10;counter++)
        {
                 SerTx('Y');
                 SerTx('E');
                 SerTx('S');


                }

}


        void SerTx(unsigned char x)
        {
           SBUF = x;
                 while(!TI);
                 TI=0;

        }

for loop has executed 10 times well in Simulator- It will print on 10 time , But if I flash it.. It keep on printing that message where is it going.

Something with Bootloader and main thing , I feel

Your Suggestion of while(1); is correct. I have tried it. But I am trying to figure out the reason why main is getting called again and again when , code is flashed to Controller

because Keil in their infinite wisdom makes a return from main() cause a reset.
