A communication method allows a host to access and send commands to an apparatus across a network or communication system by encoding data as a sequence of status signals and sending the data from the host on a communication channel between the host and an auxiliary device. The apparatus detects the status signals sent on the communication channel and decodes the status signals to retrieve the data. The apparatus further comprises a data filter to filter keystroke data by removing break code data. The keystroke data can be reconstructed by the host.
