What does "upsc 1LRES850" do?  What is the output from "ifconfig -a" for the 
local network interface?

ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP 
ECHO_RESPONSE from a host.  This is not the same TCP/IP protocol used by 
commands such as upsc.

Surprising, I would expect to see

    upsd [506]: Connected to UPS [1LRES850] usbhid-ups-1LRES850

What happens on .235 if you type "upsc 1" ?
