The IEEE-488 bus remote line is asserted. If the computer is the active controller and primary addresses are specified, it listen addresses the devices to switch them to remote mode. The remote line is asserted if the computer is the system controller and ISC select code is specified. The IO-path or device-selector must refer to one or more IEEE-488 devices or to the IEEE-488 interface select code.
If the computer is not the system controller or it is not the active controller and primary addresses are specified, an error is generated.
