Hi,
I know this is probably an amazingly dumb question, but what *exactly* does it mean when an Ethernet link is connected? Does that mean it can sense the media, and it does some kind of test to make sure it can send and hear uncorrupted frames on the segment?
It sounds like a really silly question, but I can't seem to find a definitive answer to it anywhere, everything just says "if the link light is on, you're connected"... ok, but what *exactly* does that mean? I ask more out of curiosity than any practical reason :)
Thanks!
