| |
When I disconnect my UPS from the wall, I have to wait 15-30 seconds before the USB drier 'polls' this information and tells me that the UPS is on battery power (via knutclient or syslog via nut):
ups@p34 POWER ALERT on Fri Jan 26 12:49:29 EST 2007
With a serial connection, I would get the alerts IMMEDIATELY (0.5-1 seconds) after disconnecting the UPS. My new machine does not have a serial port built-in, only a serial header, and of course does not come with an included cable, so I chose to use USB.
My question is, how do I change the polling time for the USB subsystem to match that of the serial port, or would I not want to do that for other reasons?
The reason I'd like to is I am not going to see any power alerts for unless there is a power outage for longer than 15-30 seconds.
