..And the manual is rather unclear on several things, and incorrect on others. (The serial packet example is missing the last byte from the first message, and is unclear whether the last packet should still have a serial number in the birst 6 bits as well as a 1 in the 7th, or ONlY have a 1 in the 7th.. I need to get one of these and just hook it up to my PC first, get the serial connectio down.)

All in all, a very doable project, and one I wouldn't mind attacking.

Me.
