    I found a copy of this on github and grabbed a copy of that. Wrapping it in a c++ class that works in my app framework, I ended up with the slickest little memory montor.

    Thanks guys!

    Looking for the Serial library

    I'd like to create a class that you pass in the address to whatever serial object you are using. But, I can't find the Serial library to see how its derived. (Using a Mac) Anyone?
