Thanks for the info.  That seems to work for the UPS.  I'll check on the
modem in a bit.  I'm not sure when or what changed the group though.

I looked at the udevcontrol man page, I didn't see anything in there
about restarting or reloading the rules.  Surely they have a way to do
that.  I can't unplug and plug back up the serial port.

Anybody else know how to "reset" udev??

Thanks again.
