All,

I just got my first 2.11BSD login: prompt off a TELNET session
to SimH's IP address:

OK, that's SimH starting up 2.11BSD. Now let's log on to the console:

Looks good, no? :)

Now a TELNET session from my VAX to the IP address used by the SimH
PDP-11:

------------------------------------------------------------------------

{falafel:/} # telnet pdp-11
Trying 10.0.95.251...
Connected to pdp-11.
Escape character is '^]'.

It works!
I still have to optimize some stuff... SimH is _very_ slow when packets
come
in. I can't yet tell whether this is because SimH is acting up, or
because of
the way Win32 handles my ethernet passthrough code. Probably the first,
because
when debugging is enabled, I can see a truckload of "packet dropped"
messages,
which kinda tells me it's getting overloaded with packets...

But: SimH now had a DEUNA Ethernet emulator. For now, very raw and it
will
only run on the PDP-11 CPU, although back-porting it to the PDP-10 and,
later,
the VAX CPU, will be easy.

Once I have this code cleaned up, I'll clone it to the DEQNA card model.

Cheers,
Fred
