- *  The following snippet is an example of how this module may be used within a typical

- *
- *  \code
- *      // Initialize the serial USART driver before first use, with 9600 baud (and no double-speed mode)
- *      Serial_Init(9600, false);
- *
- *      // Send a string through the USART
- *      Serial_SendString("Test String\r\n");
- *
- *      // Send a raw byte through the USART
- *      Serial_SendByte(0xDC);
- *
- *      // Receive a byte through the USART (or -1 if no data received)
- *      int16_t DataByte = Serial_ReceiveByte();
- *  \endcode
