No mgetty (or getty) running.
Since posting, I've determined:
/dev/ttyS1 works *once* after each boot,
but when I then kill pppd, it never works again.
/dev/cua1 doesn't care -- always works fine.
Maybe killing pppd has something to do with it.
Is the kernel not cleaning up properly on close of /dev/ttyS1 ??
