Roman, do you have access to two computers?
Try using something like picocom or screen(on linux) or Hyperterminal (on
windows) to chat between the two. For example, under linux:
Laptop 1:
screen /dev/ttyUSB0 9600
Laptop 2:
screen /dev/ttyUSB0 9600
Laptop 1:
Type "Hello World"
Nothing should appear on the screen of laptop 1
Laptop 2:
The words "Hello World" should magically appear.
You can also do this using one laptop. Open two terminal windows and change
one of the device names to /dev/ttyUSB1.
If that doesn't work, it ain't a paparazzi problem!
Good luck, and I think you might be overcomplicating things - XBees usually
just magically work out of the box @ 9600.
