Thanks for the info. A method in the API sounds best (not in that much 
of a hurry). As an alternative, is the relevant pin brought out to the 
SIMM edge connector anywhere? What would be really useful would be for 
me to be able to wire in a remote keyswitch so that it is possible to 
switch on the ethernet (for programming / upgrading) and then off again 
(for battery powered operation).

Thanks,

Chris.
