Issue while programming ATMEGA644PA-AU MCU for UART communication using Arduino

Hello,

I have tried to code UART communication for MCU ATMEGA644PA-AU using arduino IDE.Baud rate was given 9600.I have given Serial.print function but still the output (hyperterminal) does not produce any output.

Do anyone have a sample code demonstrating UART communication in ATMEGA644PA using arduino IDE.
(Even sending a character or string is needed).

Urgent help required.

Regards,

void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.println("hello");
  delay(1000);
}
