We are using the CS8900A ethernet chip, hardware is no-problem and
worked pretty much as expected. The software is another matter.

The TCP/IP software is definately NON-trivial. We can get away with
just doing UDP at least for the immediate project.

I want to eventually be able to telnet to the device, in similiar
fashion to just doing serial comms. Then I could issue various
commands just using a telnet client to return status information, turn
things on/off etc. etc.

The UDP version of this requires much less effort, but requires a
custom client application. I am working on doing Modbus over UDP for
this purpose.

A SIMPLE memory efficient STANDARD UDP protocol is what I need!!!

Ask me again in a month or so... :-)
