[Nut-upsuser] Does NUT include support for older UPSD servers?

Thus I would like to be able to monitor the UPSs connected to the OS/2 systems from a linux system.  Unfortunately that appears to be problematic. The PCP 4.x software appears to use Lan Server for its network protocol while the later APC software uses TCP/IP for networking. The Windows/WfWG version of 4.x lacks network support.  The linux version of 4.x is not binary compatible with modern linux systems and is closed source.

So if I understand correctly, it is not possible to run the later PowerChute Plus software (that supports TCP/IP) on the OS/2 systems?

Given this, I am posting this to ask if there is backward compatibility in your package that would permit me to monitor my UPSs connected via the OS/2 UPSD 4.2.3 software.  If not, I guess I will need to look elsewhere.

I don't think NUT has support for talking to PowerChute (unless it is hiding under a different name), but if we were to develop something for it, we would probably only target the TCP/IP interface.

If it is possible to get the OS/2 boxes to speak the PowerChute protocol over TCP, you might have some success with apcupsd:

This is all speculation, however.
