I've managed to modify my RaQ4 UPS config files to avoid the 
immediate shutdown of the APC BackUPS, but the machine does not seem 
to recognize "on battery" or "low battery" status (the LCD says 
nothing).
Could you detail a bit your modifications on the XTR? Anything beyond 
/etc/sysconfig/ups?

Thanks!

This is because of the very primitive way the BackUPS uses the serial 
port. You need the correct APC cable (not a regular serial cable) and 
definetively change something on the RaQ (/etc/sysconfig/ups, 
"MODEL=backups"); since the standard behaviour with the SmartUPS 
driver is to raise the wrong signal on the serial port and shut down 
the UPS.
More changes may be needed (see above)...
