Thanks Brian for the good hint!

It's for a client of a serial bus, answers tipical delay is below 1 second.
It's a program that interacts with a domotic system where electric modules
are switches and I would like to interact to switch the on/off and do other
pretty simple operations.
My goal is to handle an object (e.g.: ElecticSchema) where I can
tab-complete on existing modules, where I can tab-complete on single exits.

I see that IPython.kernel.twistedutil has ReactorInThread, and the docstring suggests:
rit = ReactorInThread()
that's all I needed to get to my first working prototipe. Thanks a lot!
This really solves my need, just for completeness the next question.
On the twisted ml i ws suggested to test twisted.manhole.telnet. I could get
to a nice different approach that allows me to get to a running reactor via
telnet. The only problem is that I was not able to enable tab-completion at
that level. Is it possible to start an IPython shell from manhole?
