I do have ethernet, and that is something I want to do as well.  Since I'm
trying to squeeze as much learning out of this as possible, I wanted to
start with the serial connection (though that part requires more rewiring
of my brain than a 9fs mount).  At the moment, I use a linux box with
ser2net.  I noticed that when I use rcpu to connect to my cpu server, I
don't see the /dev/eiaU* either.  (I still have to investigate Jacob's note
about /shr).  For now, I was hoping to mimic
https://www.youtube.com/watch?v=TFhQi0xbrOk where adventuresin9 uses

rimport -b DemoCPU '#A' /dev

to bind the audio device of the cpu server, except using '#t'.

Anyway, I'll keep beavering away.
