SoftwareSerial/AltSoftSerial using different ports

I probably will. But I'd still like to understand why the port change is not working. Or, for that matter, why I seem to have the same problem changing hardware serial ports. I have the same issue on the Mega when trying any of the other ports:

void setup() {
  Serial1.begin(9600);
}

void loop() {
  byte x = 3;
  delay(500);
  Serial1.println(x);
}

No TX LED blink, or serial monitor output. Do I need to tell the serial monitor to pay attention to Serial1 instead of Serial or something?
