void delay(void);
int i;
void main(void)
{
BRGH=1;
SPBRG=0x19; //BAUD RATE SETTING
SYNC=0; //SELECTING ASYNCHRONOUS MODE
SPEN=1; //SERIAL PORT ENABLED
TXEN=1; //TRANSMISSION ENABLED
while(1)
{
TXREG=0x45; //SENDING CHARACTER 'E'
delay();
while(!TXIF); //WAITING TILL TXREG sets
TXREG=0x54; //SENDING CHARACTER 'T'
delay();
while(!TXIF); //WAITING TILL TXREG sets
}
}
void delay()
{
for(i=0;i<30000;i++);
}
in need of urgent help.

Hi,

The value doesn't appear as required when the baud rates of your controller and pc don't match. PCs normally have a baud rate of 9600bps.verify your baud rate.By the way, which controller and at what frequency are you using your application?
