You have a tiny bug in the fallback code where a COM number is not entered.
You need to change serial.Serial(i) to serial.Serial('COM' + i), as you did in
the try clause agove that.
for i in range(256):
s = serial.Serial(i)
Overall the code looks fine, very Pythonic in style so far. Although I'm not
in Portland, I look forward to seeing where you go with this.
Looking over your website, FascinatingElectronics.com, I see you do really
neat controllers. For more complex serial protocols, you might want to look
into the Twisted Framework for Python (http://twistedmatrix.com/). It
provides some nice asynchronous event processing facilities, where you can
easily design your own serial protocol and interact with it cleanly. It takes
some work to understand the async way of programming but once you do, it is
