I thought I did state this, but perhaps I wasn't clear.  The server (master),
always had "NETSERVER on".

The client (Slave) is a Windows 7 computer and I had "NETSERVER off".  With this
setting the client showed COMMLOST. 

When I commented out "#NETSERVER off" on the WIN7 client and restarted the
service I got "ONLINE SLAVE" on the client and all was well.

Since Wolfgang wrote saying that commented-out is the same as "NETSERVER on"
(default), I have to conclude that NETSERVER must be set "on" for any network
communication, client or server. If this is the case, the comments in
apcupsd.conf should be changed as they lead on to believe that "off" is for
clients/slaves. 

Perhaps your man page example should be (my changes in {braces}):

NIS CONFIGURATION DIRECTIVES

NETSERVER [ on | off ]

Turns the network information {service} (NIS) on or off.  When on, apcupsd
serves status and event information over the network {and, as the client,
receives status and events information.} This information is also used by the
web-based CGI monitoring programs.  The default is set to on.

As I said, seems like it should be "on" for the client as well, at least for
Windows clients.  Also, if "slave" is the "old terminology" then we should use
"ONLINE CLIENT" instead of "ONLINE SLAVE" in the Windows status box.

Thanks a lot for your work. Despite this and the driver installation
documentation confusion, this is overall a great program and I appreciate the
efforts of everyone who worked on it.
