[Nut-upsuser] APC SmartUPS 3000VA LCD not connecting

[Zach La Celle]

We recently had to replace an old APC SmartUPS 3000 with a newer 3000VA 
(the 2U one).  It has both serial and USB in the back (with an RJ-45 on 
the end of the serial cable).

I can't get the apcsmart driver to connect.  I figured it should work 
the exact same as the old UPS, with /dev/ttyS0 as the port (I'm using 
the same port on the server that the last one was plugged into).  I even 
tried the USB driver (usbhid-ups) using the port=auto, but it complained 
about unsupported UPS.

Any ideas about connecting this new UPS?
