Supported Platforms: MODM7AE70

The Serial Empty Callback example demonstrates a robust process for triggering a specified action upon complete transmission of all data written to a specified serial port. The expected use case for this would be disabling a transmitter connected to a shared physical layer such as with RS485 or a wireless link (when using one of the device's UART serial ports).

As an aside, it should be noted that when enabling the Serial485HalfDupMode for one of the MODM7AE70s USART serial ports, the underlying hardware module will automatically toggle the RTS line for enabling and disabling the transmitter.
