[Nut-upsuser] FE700VA over USB? controlling UPSes over network?

[David Melik]

     Lately I replaced my 10+-year-old server with a nano-ITX-type one 
that has USB but not old serial ports.  I connected my FE700VA to 
DB25-to-9-to-USB cables, but haven't been able to set it up. Apparently 
my DB9-to-USB cable (Prolific Technology, Inc. PL2303 Serial Port) has 
issues needing old software (setserial?) and some new software 
(fconfigure) being changed.  Has anyone managed to do something like this?
     I'm still also interested in knowing how to control the three UPSes 
I have in the house (except FE700VA not re-setup yet) over the network, 
from one of them.  I managed to load some webpages to monitor them but 
can you shut them all off from there?
