Problem with Ultrasound Sensor

Hello LMR.

I am working on a current project but seem to be having a ridiculous amount of difficulty implementing an SRF02 Ultrasound sensor. I am using it in serial mode and communicating with an Arduino Duemilanove. The problem is not in the wiring as I triple checked that.

The adruino is supposed to send 2 bytes to the SRF02 [ address, command ] and then receive 2 bytes in response giving the distance measured by the sensor.
