Event blenders

Advanced event handling requires a way to wait for one of several events (or all of several events).
An event blender provides for this combining or blending of events. An event blender can combine up
to four events in either an "or" mode or an "and" mode. When in "or" mode, any one of the input
events will cause an output event to be generated. When in "and" mode, all the input events must
occur before an output event is generated.
When operating in "and" mode, if an event is detected more than once before all events necessary for
the generation of an output event, an action overrun will be generated. When operating in "or" mode,
an action overrun will be generated when two or more source events are detected simultaneously.
Event blenders each have an associated event detector that can be accessed through script control.
Event blenders can only be accessed over a remote interface (no front panel control is available). The
following ICL commands provide additional information on available blenders:
trigger.blender[N].clear()
trigger.blender[N].orenable
trigger.blender[N].overrun
trigger.blender[N].stimulus[M]
trigger.blender[N].wait()
