Abstract A control system for a serial data channel for a disk file is disclosed in which a microcontroller is used as the control means. The microcontroller has an input port and an output port, while the serial data channel has a data register. The connec- tions of the data register to the input and output port and the parallel by bit input and output busses on which write data and read data is sent provides a plurality of different data transfer loops through the data register which can be selected under the control of the microcontroller. The arrangement permits func- tions to be achieved by the microcontroller that heretofore were performed by another device connected to the controller or by special hardware.
