 #### Mbed OS example
 
 Common use cases for RawSerial are IRQ heavy UART operations, such as the [ATParser](https://github.com/ARMmbed/ATParser/blob/3209400df676cbf0183a5894f648c71727602d30/BufferedSerial/BufferedSerial.cpp#L29) in the ESP8266 driver. This driver uses UART on user supplied pins to communicate with the offchip ESP8266 module.
