I'm looking for a way to combine serial input with UDP (and possibly TCP) communication. Currently I have a very simple quick-and-dirty script using pyserial and the socket module without Twisted that reads line-based data from a serial port and sends it out using UDP. It works very well, but functional and reliability requirements are growing and I'm looking for a better design. New functionality that we'll need is connection to a database, two-way network communication to control the program while it's running, and perhaps the ability to use encrypted connections for the output data. Twisted seems nice, but apart from a few simple hello-world-style test I don't have any experience with it. It doesn't seem too difficult though, except for one thing: I can't find any concrete information on how to combine serial communication and network communication. What reactor do I need? How do I initialize it? How can I make it listen to both a serial port and one or more UDP and/or TCP ports? I need to do this on Linux, but it would be nice to have it working on Windows too.
