Yeah!  That works.  My serial port test program now completes without error and the test sending characters to “cu -l /dev/{dt}ty01” also works.  Of course, the serial console continues to work, so I am not (yet?) seeing any downsides.

Is there a reason not to commit this?

Thank you so much for your help!  Especially for the quick fix.
