It's all happy now thanks to Christos Zoulas and Christian Limpach.
   
   The first thing I did was try out the sabtty support. I have an AceCat
   III tablet and a Garmin GPS that I would like to drive from a 'real'
   computer. Can anyone explain why the SAB based serial ports are now
   ttyh0 and ttyh1 instead of ttya and ttyb? The lack of a manual page
   didn't help me find the new names either. Mutter, grumble...

"now"?

ttya/ttyb refer to the 'zs' based serial devices.  ttyh[01] refer to
the 'sab' based serial drivers.  it's always been like this in netbsd.
   
   If nobody else has a manual page squirelled away somewhere, I'll whip
   one up and submit it.

that would be nice...
