How can I know if a given wired connection is in full or half duplex?
I know how to check the settings but most adapters are set to auto-
negotiate and I don't know what was negotiated. Some switches will
tell you on their status lights but there's got to be a way to query a
system and get it to say if it's running in full or half. I"ve
searched everywhere and just find tons of answers about how to change
settings on a card. That doesn't give me a way to check the current
state. Thanks.
