I built a stutdown controller with a 5 volt output to Pin 8 on the serial port. This is to simulate a UPS device. I configered the UPS setting in Windows XP with negative polarity to hibernate when there is a drop in voltage. The default time it takes for WinXP to go into hibernation is 30 sec after it detects the drop in voltage on the serial port. Is there anyway to decrease this time?
No announcement yet.
