How about adding a cheap UPS. A 900W UPS runs for ~80.00 and can power an
old PC for >1 hour. If you hook up an old laptop, it can run for hours
without power.

Does your microcontroller store data onboard?

I believe a decent external modem can be set to auto-answer with the proper
AT command. Perhaps give that a try? Just hook up a modem directly to the
RS-232 interface?
