Detailed Description

UART device status flags,.

A combination of these status flags is used by the _ioctl() commands UART_SETSTATUS and UART_GETSTATUS.

Define Documentation

#define UART_FRAMINGERROR 0x00000001UL

Framing error.

UART_SETSTATUS will clear this error.

Definition at line 411 of file uart.h.

#define UART_OVERRUNERROR 0x00000002UL

Overrun error.

UART_SETSTATUS will clear this error.

Definition at line 417 of file uart.h.

#define UART_PARITYERROR 0x00000004UL

Parity error.

UART_SETSTATUS will clear this error.

Definition at line 423 of file uart.h.

#define UART_ERRORS (UART_FRAMINGERROR | UART_OVERRUNERROR | UART_PARITYERROR)

UART errors.

UART_SETSTATUS will clear all errors.

Definition at line 429 of file uart.h.

#define UART_RXBUFFEREMPTY 0x00000040UL

Receiver buffer empty.

Definition at line 433 of file uart.h.

Referenced by UsartIOCtl().

#define UART_TXBUFFEREMPTY 0x00000080UL

Transmitter buffer empty.

UART_SETSTATUS will immediately clear the buffer. It will not wait until the remaining characters have been transmitted.
