MarshallSoft have kindly allowed their DLL to be used free of charge as part of the Python package provided a brief message is included with any distribution. The core DLL is not Open Source but has been heavily tested and won several awards.

The Serial package uses SWIG (see Chapter 22 ) to create a Python DLL wrapper around the library, and provides easy-to-use Python wrappers and examples.
