PEP_ACPI_SPB_UART_RESOURCE structure (pepfx.h)

The PEP_ACPI_SPB_UART_RESOURCE structure describes an ACPI UART serial bus resource.

Syntax

typedef struct _PEP_ACPI_SPB_UART_RESOURCE {
  PEP_ACPI_SPB_RESOURCE SpbCommon;
  ULONG                 BaudRate;
  USHORT                RxBufferSize;
  USHORT                TxBufferSize;
  UCHAR                 Parity;
  UCHAR                 LinesInUse;
} PEP_ACPI_SPB_UART_RESOURCE, *PPEP_ACPI_SPB_UART_RESOURCE;
