Specify callback function to execute when CD, CTS, DSR, or RI pin changes state
You configure PinStatusFcn to execute a
callback function when a pin status event occurs. A pin status event
occurs when the Carrier Detect (CD), Clear to Send (CTS), Data Set
Ready (DSR) or Ring Indicator (RI) pin changes state. A serial port
pin changes state when it is asserted or unasserted. Information about
the state of these pins is recorded in the PinStatus property.
Note
A pin status event can be generated at any time during the instrument control session.
If the RecordStatus property value is on,
and a pin status event occurs, the record file records this information:
The event type as PinStatus
The pin that changed its state, and pin state as either on or off
The time the event occurred using the format day-month-year hour:minute:second:millisecond
