protocol for the original Data Link (50 or 70?) is implemented. sketch fully able to replace the Notebook Adapter as well as work with
this library, and software for capturing and decoding packets from the
original software.
Currently, the protocol for the original Data Link (50 and 70) is
implemented fully, the 150 and 150s partially, and the Ironman
Triathlon is being worked on.
