Serial Data into Max/MSP? Yaw Pitch Roll!

I'm a new user. Have a Wii-motion plus hooked up and loaded code from Random Hacks of Boredom: It works great, and I can see the correctly formatted data coming in though the serial monitor.

I need this data to be read by max/MSP. The serial object doesn't seem to work, even when set to the correct port (a) and the correct baud number. It won't print the data, even when prompted with bangs. Is there a step I'm missing?
