   to send bytes over the serial port, and receive bytes from the serial port. A "flush" function is provided in case the serial (UART) driver of your platform is buffer-oriented rather than byte-oriented, e.g. if the serial port is driven through a DMA module.  The

   doesn't handle flow control - the mote doesn't need it when your microcontroller is sending incoming flow control (the UART_RX_CTSn and UART_RX_RTSn lines) when your microcontroller is sending .  You will need to monitor UART_TX_RTSn and assert/de-assert UART_TX_CTSn as part of your application if your microcontroller cannot wake on data.
