Abstract
A communication system (5) provides an improved wired-OR connection for use in the bidirectional communication of information between two devices. A first device is a master host device (10) which initiates all communications while one or more slave devices (40) connected to a wired-OR common communication line either receive information from or send information to the master device. Depending on a direction of a data transfer operation, either the master or the host determines a bit time required to perform the data transfer. Furthermore, a device which terminates the bit time is the device which issues a speed up pulse for driving the common communication line to a logic one value. Such speed up pulses permit faster communication than is normally possible on a wired-OR communication line and makes high speed bidirectional communication over a single wired-OR line practical.
