Abstract
In a data processing system in which an extender unit interconnects the parallel bus of a control unit and a serial link of an extender channel, the channel and the extender unit send and receive serial frames that permit the extender unit to operate under the protocol of the parallel bus with either byte mode devices or non-byte mode devices. The control unit can be modified to operate with a byte mode device in data streaming, a high speed data transfer mode.
