BreakInterruptFcn

Specify the M-file callback function to execute when a break-interrupt event occurs

Description

You configure BreakInterruptFcn to execute an M-file callback function when a break-interrupt event occurs. A break-interrupt event is generated by the serial port when the received data is in an off (space) state longer than the transmission time for one byte.

Note    A break-interrupt event can be generated at any time during the serial port session.

If the RecordStatus property value is on, and a break-interrupt event occurs, the record file records this information:

• The event type as BreakInterrupt
• The time the event occurred using the format day-month-year hour:minute:second:millisecond

Refer to Creating and Executing Callback Functions to learn how to create a callback function.
