Abstract
A first device detects whether a second device implements full duplex communication. When the first device begins receiving a network packet from the second device, the first device transmits a jam signal to the second device. When transmission of the network packet from the second device to the first device has been completed, the first device determines whether a check value within the network packet is valid. When the check value is valid, the first device recognizes that the second device implements full duplex communication. When the check value is not valid, the first device recognizes that the second device does not implement full duplex communication.
