I am running the experimental upsd port on several FreeBSD 2.2.5-STABLE
systems with APC Smart-UPS 1000s. Every 10 minutes /var/log/messages
receives entries similar to

Jan  3 11:17:38 emu upsd[231]: apc_tune: toggle wraparound
Jan  3 11:17:39 emu upsd[231]: apc_tune: toggle wraparound
Jan  3 11:17:39 emu upsd[231]: apc_tune: negative response:    NO
Jan  3 11:17:40 emu upsd[231]: apc_tune: toggle wraparound

The `apc_tune: negative response: NO' message also appears on the
console. I believe the frequency of these messages is due to the

every 600 {
    tune "high-transfer-point"          264
    tune "low-transfer-point"           196
    tune "line-alarm"                   "0"
    tune "line-sensitivity"             "L"
    tune "low-batteries-duration"       2
    tune "nominal-voltage"              220
    tune "shutdown-delay"               20
    tune "wakeup-batteries-capacity"    25
    tune "wakeup-delay"                 0
#   tune "batteries-replaced"           "01/01/77"
#   tune "label"                        "WildWind"
}

section in /etc/upsd.conf. 

My experiments with removal of line power indicate that the shutdown
process and line restoration work properly. For the time being, I 
have commented out these messages in apc.c.

What do these messages mean?
Do they indicate a problem that needs fixing for proper operation?
Are there other programs that work with the APC Smart-UPS?
