Most likely because CURLY is an endnode, and you already have an
ethernet circuit up and running. As I said before, you can only have one
circuit active at a time.
I sortof have a recollection that you can have multiple circuits
enabled, but I might be misremembering some details.
Anyway, I suspect that you really need to turn the ethernet circuit off
here before NCP allows you to turn the IP-0-0 circuit on.
