[Nut-upsuser] megatec driver floods syslog with "UPS lost/re-established" messages

[Anton Martchukov]

Hello,

I have bought Powerman Optima 500 Plus UPS. While this
product might be unknown outside Russia, it is shipped with
megatec software and obviously works with megatec driver in
NUT. besides the following problems (I think they are
caused by one reason):

1) megatac driver is able to load and detect UPS only on 
second or third run. On the first run it typically fails.
Later if daemon is being stoped and started again it's more
likely to fail after restart too, but on the second restart 
it will mostly work ok. 

When it fails to start it outputs this to syslog:

Jul  2 22:58:53 alcor upsd[5353]: Can't connect to UPS
[powerman] (megatec-powerman): No such file or directory

2) When it starts properly it works nice, e.g. output UPS
parameters, deteact low baterry etc. besides the fact that
it floods syslog with the following message each polling
cycle of the driver

Jul  3 23:07:16 alcor megatec[7070]: Communications with UPS re-established
Jul  3 23:07:24 alcor megatec[7070]: Communications with UPS lost: No status from UPS.
Jul  3 23:07:31 alcor megatec[7070]: Communications with UPS re-established
Jul  3 23:07:39 alcor megatec[7070]: Communications with UPS lost: No status from UPS.
Jul  3 23:07:46 alcor megatec[7070]: Communications with UPS re-established
Jul  3 23:07:54 alcor megatec[7070]: Communications with UPS lost: No status from UPS.
Jul  3 23:08:01 alcor megatec[7070]: Communications with UPS re-established
Jul  3 23:08:07 alcor megatec[7070]: Communications with UPS lost: No status from UPS.
Jul  3 23:08:14 alcor megatec[7070]: Communications with UPS re-established
Jul  3 23:08:29 alcor megatec[7070]: Communications with UPS lost: No status from UPS.

I have tried different settings of polling cycle for the
dirver and believe that it does not affect the presence of
this message at all.

Any help/directions will be highly appreciated. I know a bit
of C and willing to try to solve this problem.
