Yes, but there might be a way to control this behaviour from Python. On
Unix systems you can use the termios functions to turn flow control on
and off. This doesn't help you on Windows, but curses also has raw() and
noraw() functions which do that (among other things) and might work on
Windows, too. However, curses does a lot more than just control flow
control, so it may not be appropriate for the OP's problem.
