Pinouts arn't the same across the 2000 range of modules, not checked the
3000's

The 3000 is the cheapest core with onboard magnetics. As for why choose the
2200, well the 3000 series wasn't around way back when I got my dev kit :(

As mentioned above check that the core has the same pinout, I think they
may
do in the 3000 series. As Dave mentioned with the new release of the
compiler then you'll get all the libraries you could ever need. I'm looking
at an upgrade, hopefully to a 3000 dev kit just to get the additional libs.

Lastly , will I find that I should have (need) the extra µC/OS-II
Real-Time Kernel as well ? Application is the xAP gateway (embedded
version)
- ie Ethernet udp plus 2 serial ports at mid speed.

I think you'll be ok without uC/OS-II  at least in the first instance.

If  you want a chat I'm normally on MSN.
