How does your application know, it has to enable flow control, just because it
outputs something to the screen?

Yes, but it depends heavily on the application and requires knowledge of the
application about the underlying driver architecture. Interrupt driven code
would work automagically without the application knowing what's going on
(including hardware flow control!).

Admitted, for your purpose polling may be ok, but for my taste it's not
generic enough to be used as general purpose code.
