ok, i don't think isaw this answered anywhere, so here goes:
with this circut, if i read the thread correctly, it triggers the generic ups service after ~90 sec. after Vacc goes cold. Once the UPS is triggered, it shuts down the machine, and cuts power to the inverter. Pin 4 on the com port is +5vdc? Can i set it to hibernate instead, and can i set it to hibernate say after 10 minutes? am i going to get annoying error messages from the UPS service? If it's going to hibernate after 10 minutes, do i need the caps?
also I like hibernating it better, cause i find that there's almost no chance of the machine hanging.
