BS2/RFID Reader HELP!

Our group has purchased an ID-20 RFID Reader http://www.sparkfun.com/products/8628 and a basic stamp 2 microcontroller with its compatible development board. We are trying to find out how we can read the data the reader sends out when reading a tag into the program.

    According to the video (the datasheet didn't seem to say as much) the reader sends out a 12 byte ASCII string representing the tag ID. With this information you could easily adapt the code for the Parallax RFID reader to read these tags as well. At first glance you'd need to change the baud rate value in the code for 9600bps instead of 2400bps. You would also take out the WAIT($0A) section in the code and increase the buffer to 12 bytes instead of 10, making the necessary changes in the code.
