This is a very small pull request, which accomplishes two things. First, it removes the final use of six from a unit test and from the requirements list. Second, it updates to pyserial 3.1. While this change is a breaking change (their API has changed), I was unable to find documentation for old versions of pyserial, making it very difficult to understand their code. This will help fix that problem by bringing us up to their latest version, 3.1.1.
