OK - I spent some quality time with my MP2100 this morning, and have
some observations (in no particular order):

 - When I initiated my TCP/IP connection from either NetHopper or
Courier, and then quit the browser and launched Dock, the Dock
connection to NCX came up quickly, and I was able to perform NCX
functions, with no problems.

 - When I initiated my TCP/IP connection through the Dock, it was hit-or-
miss whether I would get a TCP/IP connection established.

 - It seemed as though the more attempts (good or bad) I made to connect
to TCP/IP. the slower my MP2100 ran (at least as far as trying to
establish a TCP/IP connection, but maybe other processes as well).

 - I had Console running on my Pismo while doing my testing. NCX puts
out messages to Console.log while it is running. With respect to
ethernet, it 'normally' puts up this one at startup:

[Date] [Time] NCX[9800] Net service will publish.

Upon disconnect from my MP2100 via closing Dock, I got this one:

[Date] [Time] NCX[9781] Not listening for ethernet connection: error -98205.

I quit NCX and restarted it immediately, and got the same message!

I then quit NCX, waited about a minute, and restarted it, and got the
'Net service will publish' message.

So, it appears that I have identified two 'workarounds' to ethernet
connectivity via NCX:

1) Make a TCP/IP connection first before trying to connect to NCX via
the Dock and TCP/IP;
2) If, for some reason, the connection between the Newton and NCX over
ethernet is terminated, and you want to perform more tasks with NCX, it
may be better to quit NCX, wait a minute or two, relaunch NCX, then carry on.
