Actually, never mind, on re-examining the documentation I figured out
it's serial.  I gave it a try and it detected the UPS, but failed to
establish communication:

minbar:root:~:4 # /lib64/nut/powerpanel -a backstop-pp
Network UPS Tools - CyberPower text/binary protocol UPS driver 0.27 (2.7.4)
Warning: This is an experimental driver.
Some features may not function correctly.

CyberPower UPS with text protocol on /dev/ttyS0 detected
Communications with UPS lost: Status read failed!

According to
https://networkupstools.org/ddl/Cyber_Power_Systems/PR3000E.html, at
least the PR3000E is known to work with powerpanel, but apparently I'm
missing something.  Anyone have any hints to offer here?
