[Nut-upsdev] Problem with bestfcom and old Ferrups

I have an old (1997) Best Ferrups (model FE18KVA) that I am trying to
monitor for the first time, but all the Best drivers fail to communicate
with it.

In ups_sync() in bestuferrups.c and bestfcom.c, the "time" command is
sent and a one-line response is read.  However, on my UPS, that command
returns the current time and then prompts for a new time setting.  I
worked around that by just sending another "\r" (on an UPS that doesn't
prompt for the time that will just send an empty command and return
another prompt).  I added:

	execute("\r", buf, sizeof(buf));

to the end of ups_sync().

However, then neither bestuferrups or bestfcom recognize my UPS.  It
does not support the "fc" command, and bestfcom rejects the output of
the "f" command, which is:


bestuferrups rejects the output of the id command, which is (the ^L^Z is
actually the control codes):

I don't speak for anybody but myself - that's enough trouble.
