I have reversed some days ago a protocol on the nitram UPS (a low end
UPS) which is in fact a Cyberpower UPS.
The protocol is not the same as cyberpower.c but an evolution. If you
can send me some dump of the communication between the UPS and the PC
(using portmon), I will take a look.

The baud rate is probably 1200 or 2400.

If the protocol of Cyberpower CP550SL/AE550 Serial is like the Nitram
one, I will update nitram.c.
