Abstract
A datalink for a system of N computers, and M monitors and peripheral devices is described. Separate state machines are provided for each switched computer, and separate state machines for each switched workstation, with a non-intrusive matrix switch disposed there-between. The matrix switch routes the peripheral data streams without intercepting them with a processor. The computer-side state machines and the workstation-side state machines are in a master/slave relationship, respectively, and communicate peripheral data using a half-duplex method of transfer.
