Details

This event may be generated only after the ser.notifysent method is used. Your application needs to use the ser.notifysent method EACH TIME it wants to cause the on_ser_data_sent event generation for a particular port. When the event handler for this event is entered, ser.num is automatically switched to the port on which this event was generated.

Please remember that uncommitted data in the TX buffer is not taken into account for on_ser_data_sent event generation.
