This mode turns out to be very useful to me. I have only 1 port SCC1 that can be used by the diag interface as well as printf. I used the hal_diag.c from mbx port and it does not work with the interrupt driven driver so when I started with the interrupt driven driver, it would go hang because of the diag_printf.

Anyways I do have the interrupt mode driver working now but only by disabling diags. I have to see how to make the 2 co-exist on one port (probably polling mode driver for debugging).
