OK, here we go with exactly what I get with the new kernel with
NKL = 8 and entries in /etc/dtab for 7 serial lines.

2.11 BSD UNIX (wizard) (console)



So, the serial line still don't work and the for some reason the
network won't come up.  Looks like more research needed for this.

And now for today's humor.

During one of the recompiles of the kernel (I had to do it a
couple times to get the BASE and Overlays right.  Boy did that
bring back memories.  Glad to see I still have the knack for
doing them.) I got the following message:

  base segment is 49152, min is 49152, too small by 0 bytes.

And, of course, it said the kernel was not BOOTABLE.  Maybe that
should say "min is 49153".   :-)
