I don't understand - I've used SCC1 for both serial and diag at the
same time.  I don't have an MBX860, but I do have other QUICC boards.

I just tried this on my Viper/860, using SCC1 as the serial console
and it worked perfectly, mixing diagnostic I/O and large amounts of
serial I/O via the serial driver.  The program and kernel setups
are attached.

I think you must have some other problem, possibly dealing with
interrupts.
