This short example will echo back every character you type to Serial Monitor. This should work on any Arduino.

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

void loop()
{
  if ( Serial.available() )
  {
    int c = Serial.read();    
    Serial.write( c );
  }
}

Make sure the Serial Monitor has the matching baud rate selected
