Oh absolutely. I don't dispute that. Given infinite time as you said. But I gained a 5x reduction already. I would prefer moving to some other part of the kernel where another 5x reduction could be achieved now rather than postponing that after I'm done rewriting the interface for all UART drivers. Maybe someone else will feel inspired and take on this UART driver modernizing task (that could be a nice mentorred project for example). PS: FUZIX is a real piece of art ;-) Nicolas
