Yup, the place jbeynon mentioned is the place to obtain info on the serial interface to get your PC to talk to the module. The only problem is that the "kit" is no longer available and you'll have to cobble it up yourself. I haven't done that yet 'cause I've been waiting for somebody like you to come along and do the hard part. If you can come up with a good GUI-based solution I'll be first in line!!

Good luck!
