Changing a command to use the _slow send variant, as it is apparently needed for the old Lumina.
Modifying the response manager code in a subtle fashion to handle long periods of dealing with bad input. In this case it involved a Lumina 3G sending 'timed out' invalid 7-byte packets in concert with valid external input/light sensor input.
Modifying the way the tests operate. Now there is only a single response manager instance and a single fake device connection, which makes the entire suite into a sort of a stress test, with internal response manager state and perhaps even fragments of fake input being carried over between tests.
