How would you do that? IFAIK, there is no way in Python to kill a thread. The usual work-around is to have a global flag that you'd set to True when the main thread wants to close the port. The read would have a timeout of 1 second of so, so that the reading thread is woken up every second, so it can check that flag and wind up when the flag is set.
