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.
