[Nut-upsuser] Monitor UPS Brand SMS

[David White]

I am far from expert on these matters. But have a couple questions:

1. Are you sure that /dev/ttyUSB0 exists and is the result of the 
Prolific USB->serial converter? For example, if you yank the Prolific 
and reboot, is /ttyUSB0 there still? It is possible that there is 
another /dev/ttyUSBx out there.I doubt this but wonder.

2. I have recently been fuddled due to permission problems of various 
sorts. Are you sure that the user under which nut is running is able to 
access the /dev/ttyUSB file?
