connections are made on a conventional data processing system.
Fox further discloses in column 17, lines 4 through 12, that
once the processor is connected, it transmits its commands
and/or data to the CACU, and they are performed or transmitted
by the CACU to its addressed outboard
units. When the processor stops the transmission or
interrupts its transmission beyond the predetermined time
period, the connection is broken and the CACU becomes non-busy
and thereby is selectable by any processor which thereafter
