9DOF Razor flow control [SOLVED]

Solved this with a reply on the sparkfun forums. Should anyone search for a solution to this the code I’ve used is:

if (Serial.available() > 0) {
     receivedByte = Serial.read();
     if (receivedByte == 'a'){
        printdata();
     } 
   }

This is exactly what I have used for my Razor
