* XBee IO port 3 is a somewhat-arbitrarily chosen pin that can be

|
* connected directly to the AVR reset pin.
|
|

|
|
* Note that port 7 was not used because it is the only pin that can

|
* be used as a CTS flow control output. Port 6 is the only pin that
|
|
* can be used as an RTS flow control input.

|

|
|
* Some off-the-shelf Arduino shields select a different pin. For
|
|
* example this one uses XBee IO port 7.
