This goes directly through the serial port on the Robot.

I am working on a bit of Arduino code that will let me see if the serial port is being used for anything.

I think the following will work:

void setup() {
  Serial.begin(/*Maximum Serial Rate*/);
}

void loop() {
  Serial.println(Serial.read());
}

Assuming you have your arduino hooked up to your laptop and the robot's serial port hooked up to the arduino with the TX to RX and the ground, or Pins 2 and 5.
