[Avila] Redboot via ethernet

[David Boreham]

Probably a very dumb question (it's been 15 years since
I last worked with embedded systems...) but on a from-the-factory
board flashed with redboot and uclinux is there a way
to either force redboot to talk via ethernet ? Mine boots all
the way into Linux and I can telnet to it in that state.
I'd like to tell it to drop back to redboot, or alternatively
have some way to force redboot to halt before it boots
linux.

Can this be done, or do I need to break out my serial cable
from behind the glass panel on the wall ?

Thanks.
