Xtend or Xtream to Xbee

Hi. I am used to working with Digi Xtend and Xstream modems and have several of these at my disposal, but I have just ordered my first Xbee device to use for a microcontroller project.
Is it possible to use either an X-tend or an X-stream as a base connected to my computer to communicate with an Xbee on the receiving end?
If so, does anybody know what the configurations of each device should be?
