RS-232 Wireless comms with XRF radio

Hey peeps

My first post in a very long time...

I've got a project on the go at the moment, gonna post it as a robot soon, which is a robotic dragon quadruped called Dimitri (not sure why, but I like it)

Since an Arduino isn't clever enough to do all the things I'd like this robot to do, I'm gonna have most of its brain inside my laptop and communicate wirelessly.

I'm having problems getting a connection with my current setup, here's a photo:

On the left is the Arduino with the XBee shield and XRF radio mounted, the two wires are only there to power the other XBee shield, which has no Arduino attached, which is wired to the serial to USB converter at the bottom of the picture.

I'm not sure whether I need to connect anything else - I thought since the XRF radios act as transparent serial connections then simply using Serial.print() on the Arduino would appear on a serial monitor on the PC...

Am I missing something obvious?

All help greatly appreciated :)

I was under the impression

I was under the impression that the V out of the serial converter was 5v, and the radios use 3.3v but the shields have resistors to do the level shifting
