Hi! I need to create a simple program to check and monitor the state
of the pins on a serial interface on a ups. I want to be able to tell
what pins are in what state and when but I don't know where to start.
Can anyone help me!
I have searched all over, including google code (which is hard if you
don't already know what you are looking for, but I can't find anything
that will help me to get started. It seems really simple. I have a
Linux computer and a ups, with a serial cable connecting them. I want
to "see" which pins change their state when the power goes out and
when the battery gets low. The plan is to use this to trigger other
events that have NOTHING TO DO WITH SHUTTING THE PC DOWN.

If anyone has any kind of advise that I might be able use, then please
give it to me.


This have nothing to do with C++, try a group discussing Linux instead.
A hint, perhaps check if you have something in /dev for that serial
interface.
