Good job cutting down the sample.  Naturally, it'd have been smart to 
tell us you don't get the same traceback this way.  But it looks like 
the first problem is in that missing __init__() method.  Instead of 
saying "it doe not work" it'd be good to examine just what error 
traceback you got when you did have it there.  I suspect it's because 
you're passing parameters in when you invoke it  (iodev, baud_rate = 
57600)  but you don't have any arguments.  You don't even have the self 
argument.

You are also missing the super call, as outlined earlier in this thread. 
  So the base class won't being properly initialized once you fix the 
first problem.

Reread Thomas Rachel's message, and if you still can't make it work, 
tell us what errors you still get, or what you don't understand.
