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

I have a network with two older systems protected by APC UPSs.  Both 
systems run OS/2 and will continue to do so.  Both systems have APC 
PowerChute Plus 4.2.3 installed and I can use that software to monitor 
and control both systems.

I am also now running several linux systems, in fact I spend almost all 
my time on the linux systems and these OS/2 systems are servers running 
in the background which need to be protected.  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.

I have posted on the APC forums and they have had nothing further to 
suggest to me other than to check third-party software or run the OS/2 
software in a virtual machine.  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.
