Is anyone working on anything to support the Cyberpower CP550SL/AE550 Serial? Any idea if it uses the same or similar protocol as the other Cyberpower models? I have an HP 4952A Serial Protocol Analyzer and a Cyberpower CP550SL. Once I get the CP550SL up and working in Windows over RS232 I'll hook up the 4952A and see whats going on. I'm not sure what it uses for default baud rate. The 4952A is limited to 38400. Is anyone interested in any information I might gather from it? Suggestions as to which if any driver I should start from would be appriciated. Ideally I'd like to add support to the cyberpower driver as patch if its at all similar to that protocol. This is rather lower end UPS, but for 57 USD at Best Buy it looks suitable for someone on a tight budget just wanting protection from short power glitches and something that will give a small server enough time to shutdown gracefully after emailing an SOS.

To find out the baud rate, you could use portmon: http://www.sysinternals.com/utilities/portmon.html It would probably complement the HP analyzer nicely. -- - Charles Lepple

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.> I have an HP 4952A Serial Protocol Analyzer and a Cyberpower CP550SL. > Once I get the CP550SL up and working in Windows over RS232 I'll hook > up the 4952A and see whats going on.

The 4952A is limited to 38400.The baud rate is probably 1200 or 2400.> Is anyone interested in any information I might gather from it? > Suggestions as to which if any driver I should start from would be > appriciated.
