UART status codes

Collaboration diagram for UART status codes:

Macros
#define	UART_STATUS_SUCCESS   (0)
	Successful status code returned by UART APIs.
#define	UART_STATUS_SREADTIMEOUT   (1)
	A read timeout occurred (not an error).
#define	UART_STATUS_EFRAMING   (-1)
	A framing error occurred.
#define	UART_STATUS_EPARITY   (-2)
	A parity error occurred.
#define	UART_STATUS_EBREAK   (-4)
	A break error occurred.
#define	UART_STATUS_EOVERRUN   (-8)
	A FIFO overrun occurred.
#define	UART_STATUS_EINUSE   (-9)
	The UART is currently in use.
#define	UART_STATUS_EINVALID   (-10)
	An invalid argument or UART_Params field was passed to UART API.
#define	UART_STATUS_EFAIL   (-11)
	General failure status returned by UART API.
#define	UART_STATUS_EMEMORY   (-12)
	A memory allocation failure occurred.
#define	UART_STATUS_ETIMEOUT   (-13)
	A timeout occurred for a blocking UART_read or UART_write call.
#define	UART_STATUS_ECANCELLED   (-14)
	A UART_write() or UART_read() operation was cancelled.
#define	UART_STATUS_ENOTOPEN   (-15)
	A UART_write() or UART_read() called on a device not opened.
#define	UART_STATUS_EAGAIN   (-16)
	A UART_write() or UART_read() in UART_Mode_NONBLOCKING would have blocked.
