Robert,
as Itamar said: don't use thread -- you likely don't need them in your scenario.
shameless self-plug:

https://github.com/tavendo/AutobahnPython/tree/master/examples/wamp/serial2ws
The example includes both Arduino code and Twisted/Autobahn code .. communicating over serial. No locking. Everything async.
Maybe thats of use while learning ..

Thanks for the fast reply.
I don't yet understand your answer. I may have to dig more into Python.

1. Twisted is not thread-safe, so you can't call methods on the protocol from another thread.
2. As a result, you're probably best off not using threads at all.
3. A reasonable place for the write() might be in your Protocol's connectionMade method.
