In a small number of cases it's also true for the diagnostic I/O. Gary
Thomas recently added this for sa11x0 diag. You would need to include
<cyg/hal/hal_if.h> and use CYGACC_COMM_IF_CONTROL(). You can see an example
in redboot/current/src/main.c:set_console_baud_rate().
Jesper, I'd be interested in what CYGACC_CALL_IF_SET_SERIAL_BAUD() is for
in the case. Just "legacy" CygMon stuff and should be ignored?
