Thanks a lot guys for your replies.
The shield I am using is the XBee Pro Shield from Libelium.com. Too bad I can't find any documentation for this shield, but Arduino.cc has a page describing a shield from Libelium which the page describes as a "deprecated product". http://arduino.cc/en/Main/ArduinoXbeeShield
Looking at the board's bottom traces though, I figured out it does use the 0 and 1 pins for serial communication. I would like to know, PaulS, how exactly can I display such data as you stated. I do not need to input anything so, the Send button is not a problem for me.
