From the man ifconfig pages or man 4 rl it says somethign like this: ifconfig rl0/fx0 [whatever your card is] media 100baseTX would make it 100/half-duplex, only time it will go full-duplex is if you specify it: ifconfig rl0/fx0 [whatever your card is] media 100baseTX mediaopt full-duplex [mediaopt or mediaopts I always forget] Anyways if it doesn't specifically say full-duplex, it's half duplex.
