A system and a method for communicating configuration data between a source device and a sink are described. An active buffer receives data from an auxiliary communication channel which communicates data between the source device and the sink device. The active buffer modifies data received from the auxiliary communication channel. For example, the active buffer amplifies the received data or electrically reshapes the received data. The modified data is then transmitted from the active buffer to a destination device. In one embodiment, the auxiliary communication channel is bi-directional and upon receiving data from a first device, the active buffer is modified to permit uni-directional transmission of data from the first device to a second device.
