ADuC7060 Serial Download

Hi,

I've built a prototype using the ADuC7060 and ADM3202 for RS232 communication. I copied the evaluation circuits, but it doesn't work.  The WSD application just sits there waiting for the response from the controller.  I need some help understanding what is supposed to be happening on the microcontroller when I pull the pull NTRST/BM pin low. I'm also wondering if there is a way to tell if the micro is functioning properly aside from knowing I have power at the correct pins.

Attached is the portion if the schematic with the ADuC7060 and ADM3202.

Any help would be appreciated.
