CPPORT structure (uart.h)

Contains the mutable runtime state of a specific instance of a UART device.

Syntax

typedef struct _CPPORT {
  PUCHAR                            Address;
  ULONG                             BaudRate;
  USHORT                            Flags;
  UCHAR                             ByteWidth;
  UART_HARDWARE_READ_INDEXED_UCHAR  Read;
  UART_HARDWARE_WRITE_INDEXED_UCHAR Write;
} CPPORT, *PCPPORT;

Members

Address

The base address of the UART registers.

BaudRate

The UART hardware's baud rate in bits per second.

Flags

A bitmask of the port's internal flags.

ByteWidth

The width of each of the UART hardware's registers as a number of bytes.

Read

A pointer to a UART_HARDWARE_READ_INDEXED_UCHAR callback function used to read from a register on the UART hardware.

Write

A pointer to a UART_HARDWARE_WRITE_INDEXED_UCHAR callback function used to write to a register on the UART hardware.
