Note that it should be self.shell.ev (and likewise for ex()) - this
will become important soon, when we release 0.13.
I'm not quite sure what you mean about stdout buffers, but I think you
want something like this:
# e.g. cmd = "AC.OnOff"
prev_value = self.shell.ev(cmd)
new_value = self.shell.ev(cmd)
if new_value != prev_value:
print("%s changed from %r to %r" % (cmd, prev_value, new_value))
prev_value = new_value
Checking for a key is trickier, especially across different platforms.
The simplest way is just to use Ctrl+C to interrupt the code.
