I still haven't got serial cable, and work has been a lot so not yet.  I'll
let you know when I do.  Thanks for all the help.  Also, as a random
question, what is the state of support for the memory cards?  couldn't these
provide an easy place to store at the least the relevant config files?
Maybe any other stuff?  I believe they are 16MB, which seems enough to be
quite useful.  Flash memory has its issues, of course, but hey...
