[Nut-upsuser] Mitsubishi 2033C via gamtronic (SEC)?

Hi guys,

I have a couple Mitsubishi 2033C UPSes that I badly want data from. We  
used to have Mitsubishi Netcom devices which took the serial output and  
provided a web interface, SNMP, and email alerts. All of those devices  
died. They're really awful devices (they're clunky and have 386s in them)  
and not worth the pricetag for a replacement.

The closest replacement I've seen so far is a device by Chipkin but it's  
not very clear if they're actually selling it --  

After reading about the Chipkin I realized the UPS I'm working with speaks  
the SEC protocol. This is supposed to be supported by the gamtronic  
driver. My next thought is getting something like a  
Soekris/Alix/RaspberryPi device nearby and reading the data with NUT. Has  
anyone tried this before? It seems nobody even talks about these  
Mitsubishi UPSes on the internet, so it's a little scary -- I've seen  
UPSes (namely APC) decide to shutdown if you plug in the wrong serial  
cable, so I'm worried about what could happen if something malformed comes  
over the wire.

Thanks for any pointers you might have.
