couple of networks i got offer the choice of half or full duplex. They
defaulted to half so I never changed them cuz I wasn't sure what would
happen if I set them to full and the other end didn't support it. I have
looked but never found the answer.
My question is :
if i set a network card to full and its not supported will it run in half or
not work at all.?
