Vista Tutorial - Install UPS (uninterruptable power supply) in Vista

John,
Interesting, the Serial UPS that I tried had no drivers included with it,
the user interface depended on the native operating system drivers. (XP had
native serial and UPS drivers). My current USB UPS (say that five times
fast) is dependent on the native 'batteries' driver. Just as a point of
curiosity does your UPS show up in Device Manager? (Mine is labeled
'batteries).
When checking Microsoft knowledge bases they said Vista did not support
Serial.

Perhaps the OP should continue to try, starting at the manufactures site to
check for Vista drivers as well as user interface.

Yes, the APC software should work.
It's Vista's built-in power management that won't work with serial ports.

It does not show up in device manager. The APC software installs
a driver to communicate with the UPS. On XP the first thing the
driver installation did was to disable XP's built-in UPS feature. I
don't remember if that happened on Vista but I suspect that it did.

UPS uses serial port status lines such as Clear to Send and Carrier
Detect to send signals to the computer. UPS is told to shutdown using
Data Terminal Ready status line. How are these handshake signals
carried on a USB port?

Obviously if not, then USB port on Vista could not see those
handshaking signals. To understand why USB converter does nothing
useful, one would understand simple serial port functions and how USB
works.
