No worries mate, I plug and switch hot, no need to shut off the breakers, just
takes more time... Just avoid me if I'm on a ladder. less I may reach down and
touch you on the shoulder with the kiss of Edison.....

	Seriously, I'm fine with it and have a great digital multimeter as well. At

DTR, RTS and TD voltages for another little ups problem:

	I didn't want to do the yard tomorrow anyway.... I'll see if I can get the
measurements to you after dinner along with the <path/to>/usbhid-ups -DD -a
nirvana_ups. Thanks for your help. I have really been meaning to chase this
issue down.
