Thanks.  (Further poking makes it seem very likely that there's a
hardware problem -- I can log in blind and see 'root' logged in, but I
never see any output.  That makes it sound like a cable or connector
issue.)

One last question -- should wscons be on or off?

Also -- where, if anyplace, is this documented?  I see nothing in the
How-Tos or the NetBSD Guide on setting up serial consoles.
