RN-41 not responding

I just got an RN-41 module and "Bluetooth USB Dongle" from sparkfun. The dongle seems to work but the DIP module doesn't respond on the serial port or show up on bluetooth. Running on 3.3v, set the appropriate PIO pins. Any ideas? I think it's DOA.

make sure your baud rate settings are correct. 115200 8-N-1 with hardware flow control enabled. It didn't work in a terminal program I usually use, but works fine in hyperterminal. Once the settings are correct, if you send '$$$' it should respond with 'CMD'. This is how I tell that the serial is setup properly.
