Mike,
On my T3.6, it takes several seconds for all the initialization stuff to happen and print out, like this:
Serial Initialized
Loading Accel and Mag Biases and Scale Factors
Accel and Mag Biases and Scale Factors Loaded
Accel Biases and Scale Factors:
-0.043603, 1.001250
-0.043603, 1.000263
-0.340763, 0.994053
Mag Biases and Scale Factors:

Then, if IMU and GPS data is being received, you should get this:

I'm running it right now and getting this. Where is yours hanging up? Might have to put some prints in to see where yours stops. I'll think some more on it...
