I'd suggest not changing anything and just let the serial bits drop onto the 
floor (assuming that the device _could_ have a serial port, i.e. is builtin).
RedBoot doesn't need anything from the serial port and will happily accept
incoming connections on the network as soon as everything is initialized.

We've done exactly this sort of thing for customers before, so I know that
it works just fine, albeit a bit scary :-)
