The ??CL (Clear) command clears all exception flags maintained by the MCP for the specified peripheral units and terminates any task using those units.

Syntax

<unit number list>

Explanation

??CL <device type> <unit number>

Clears the devices in the specified unit number list. Clearing a device assigned to a task results in the immediate discontinuation of that task.

If the response to this command requires more than one screen, the screens are displayed at 8-second intervals.

This command is the same as the nonprimitive CL (Clear) command, except that it is executed by a stack independent of the CONTROLLER stack. This command can therefore be used even when the CONTROLLER stack is suspended.
