indeed, it's an interesting feature.

after thinking a bit, here is a potentially more useful approach, that
would complement "GET NUMLOGINS":
Add a new "LIST CLIENT" command to the network protocol [1]

Form:

    LIST CLIENT [device_name]

Response:

    BEGIN LIST CLIENT
    CLIENT <client IP address> <device name>
    ...
    END LIST CLIENT

    BEGIN LIST CLIENT
    CLIENT ::1 ups1
    CLIENT ::1 ups2
    CLIENT 166.99.250.2 ups2
    END LIST CLIENT

This would be completed by a new upsc option ("-c" for example) to get
this list.

Note that this is more an RFC, since it's just a base idea (I've not
checked all details).
So feedback and comments welcome...
Would the above suits your needs René Martin?
