[Nut-upsuser] Unable to disable beeper on Powercom Imperial IMP-525AP

[Sergey Talchuk]

Hi ALL,

Powercom Imperial IMP-525AP seems to be fully compatible with NUT.
Unfortunately, I can not disable beeper.

upscmd -u {NUT_USER} -p {NUT_PASSWORD} powercom beeper.toggle
returns *OK*, however, ups.beeper.status=enabled

Thank you,
Sergey
