Hello,

I have made a program based rs 232 port with MFC.

I want to get system call which gives me state, wether power is turn on or off.
is there any system call which gives information of powerstatus?

Thanks to all.

Not exactly sure what your trying to do, but I googled rs 232, and it sounds like your maybe trying to write a driver for a portable device? What exactly is your situation.
