Hmm, feels easier to put up a SLIP driver and a cut-down TCP/IP stack,
these already exist for 18F, and address the rig via an IP address. This
appeals to me more as a Linux guy.
Or, even easier, I could just extend my existing serial control protocol
to allow for download/storage/management/execution of milling schedules.
And if I want it to look like a filesystem to the host PC, I can always
wrap it in FUSE.
A respected friend/mentor is always saying "do the simplest thing that
could possibly work".
