That's great that you're working on some MAC algorithms, we really need them. First, though, I noticed your using /python/gmsk2/. I'd recommend updating to the newer release or 'svn up' if you use the repository. That directory is now called "digital" and does more than just GMSK. It might also have a few bug fixes related to your problem. Also, check out digital/tunnel.py for a CSMA MAC implementation. > However, now when I try to run the modified IP tunnelling example, the > program craches at either of two different points in __init__() of > transmit_path class with the message 'Floating exception'.

You're doing something with a float that can't be computed. You'll need to post more information about your specific problem for me to be of any more help. Specifically, are you changing the transmit_path.py file at all? If so, please post the changes.
