To support automatic detection of docking events for removable serial port hardware, serial port drivers can monitor the Data Carrier Detected (DCD) line. When the serial port driver detects a positive DCD transition, it can use CeEventHasOccurred with the NOTIFICATION_EVENT_RS232_DETECTED message to indicate the DCD event. Some hardware platforms that support Direct Cable Connect synchronization services will start the synchronization services when this event occurs.
See %_WINCEROOT%\Public\Common\Oak\Drivers\Serial\2890_ser\2890_ser.c for an example of detecting the DCD transition and generating this message.
