So I finally got some time to solder the headers on my XBee shield and decided, why not follow SFE’s amazing [tutorial to test it out. Unfortunately, about half way through the tutorial, right after loading the sketch into the Arduino, flipping the switch back to UART … the next line says:```
TODO: Continue.

Now, I know SFE has a sense of humor, but if this is one of those moment, uh, it needs to not be. I realize it's probably just written for one XBee and the shield, but it would be nice to expand on it for those folks, like myself, who have multiple XBees (and mutiple ways of running them: shield, explorer, and my daughter's has the Lilypad XBee shield.)

Supposedly, after following that tutorial, and flipping the switch, the XBee is transmitting (???) So how do I figure out if it really is? How do I listen with a second one?](http://www.sparkfun.com/tutorials/192)

Just above that TO DO is

Now move the switch on the shield to the “UART” position. When the switch on the shield is in the “UART” position the hardware serial port of the Arduino is used to transfer data from the Arduino to the XBee module.

So I’ll take a guess that after moving the switch, some program of yours on the Arduino’s AVR microprocessors is supposed to use the correct baud rate to begin to send and receive data via the XBee. Without a mated XBee (wirelessly), the next step might be for the AVR program (“sketch”) to do what had been done with XCTU, such as open the serial link, pause one second, send +++ and see if “OK” comes back from the XBee.
