UART Status [UART I/O Control Functions] Collaboration diagram for UART Status: Detailed Description UART device status flags,. A combination of these status flags is used by the _ioctl() commands UART_SETSTATUS and UART_GETSTATUS. Defines #define  UART_FRAMINGERROR   Framing error. #define  UART_OVERRUNERROR   Overrun error. #define  UART_PARITYERROR   Parity error. #define  UART_ERRORS   UART errors. #define  UART_RXBUFFEREMPTY   Receiver buffer empty. #define  UART_TXBUFFEREMPTY   Transmitter buffer empty. #define  UART_RTSENABLED   RTS handshake output enabled. #define  UART_RTSDISABLED   RTS handshake output disabled. #define  UART_CTSENABLED   CTS handshake input enabled. #define  UART_CTSDISABLED   CTS handshake input disabled. #define  UART_DTRENABLED   DTR handshake output enabled. #define  UART_DTRDISABLED   DTR handshake output disabled. #define  UART_RXENABLED   Receiver enabled. #define  UART_RXDISABLED   Receiver enabled. #define  UART_TXENABLED   Transmitter enabled. #define  UART_TXDISABLED   Transmitter enabled. #define  UART_RXADDRFRAME   Receive address frames only. #define  UART_RXNORMFRAME   Receive all frames. #define  UART_TXADDRFRAME   Transmit as address frame. #define  UART_TXNORMFRAME   Transmit as normal frame. Define Documentation #define UART_ERRORS   UART errors. UART_SETSTATUS will clear all errors. #define UART_FRAMINGERROR   Framing error. UART_SETSTATUS will clear this error. #define UART_OVERRUNERROR   Overrun error. UART_SETSTATUS will clear this error. #define UART_PARITYERROR   Parity error. UART_SETSTATUS will clear this error. #define UART_RXADDRFRAME   Receive address frames only. Used in multidrop communication. May only work if 9 databits have been configured. #define UART_RXNORMFRAME   Receive all frames. Used in multidrop communication. #define UART_TXADDRFRAME   Transmit as address frame. Used in multidrop communication. May only work if 9 databits have been configured. #define UART_TXBUFFEREMPTY   Transmitter buffer empty. UART_SETSTATUS will immediately clear the buffer. It will not wait until the remaining characters have been transmitted. #define UART_TXNORMFRAME   Transmit as normal frame. Used in multidrop communication.
