Ah, I think what we might have here, is a failure to communicate!
Especially on my part. :(

I'm using an SU3000RM with a network interface card installed.
The network interface doesn't provide protection for the
network. It provides a TCP/IP interface to the UPS. It has telnet
and web interfaces, and may even have an SNMP interface.

I can telnet to the UPS to monitor and control it. With the network
interface, I should not need the serial cable interface. But APCUPSD
does not appear to have the capability to connect to the UPS via TCP/IP;
to my dismay, it appears only to connect via serial cable.

So, can the APCUPSD connect to the UPS via TCP/IP or is a serial cable
absolutely necessary?
