UPS service has lost comm with UPS?
my UPS is not giving back up to my computer,and when I check power options on control panel it says "ups service has lost comm with ups?".
Apparently, XP won't allow you to access the ports directly like you would in earlier Windows versions (with IRQ and IO). So you would have to go through Windows API or something instead of direct access. Since you say the program wants the IRQ and IO of the port, it could be trying to access the port directly, which would be forbidden.
If you're using XP, I heard that XP won't let you access the ports directly like you could with earlier Windows versions.
