Well, there are still some issues concerning coding-style and design,
but those can be worked out, I guess. Still, there is one conceptual
question I'd like to ask:

Have you seen the TxRTS feature in Mode Register 2? It looks to me that
it does the same (in hardware) what you achieve with the
*_rts_clear-function and the TX_EMPTY interrupt. Or am I wrong?

Kind regards,

   Wolfram
