Have you tried this with other drivers? How about with the dummy driver?

Right, these are separate processes. I think there is also some
hysteresis in the server, so that you don't oscillate between stale
and good too frequently.

I don't see anything wrong with the log, though... if you pulled the
cable at 21:03:00, and the driver was still reporting failed comms
until 21:03:13, then upsd and upsmon were doing the right thing, given
the data provided by the driver.

In the course of debugging, you may want to do a hex dump of the bytes
that trigger the ser_comm_fail() in safenet_command().
