Ahhhhh, thank you, I obviously did not know that!

the TX pin on my arduino nano does not blink if the arduino is not connected via USB (but still powered on). If I plug the USB cable in, then the LED for TX start to flash. Does the led not flashing mean it is not sending out any data ? When not connected to usb, I have cable going from my TX and RX pin to my xbee.

All I am doing in the code is starting the Serial and writing to it. I stripped out everything else and it still doesnt work.
