  17   Convert status code value and extended data to readable ASCII string, send string to serial I/O device.
  18
  19   @param  CodeType      Indicates the type of status code being reported.  Type EFI_STATUS_CODE_TYPE is defined in "Related Definitions" below.
  20
  21   @param  Value         Describes the current status of a hardware or software entity.
  22                         This included information about the class and subclass that is used to classify the entity
  23                         as well as an operation.  For progress codes, the operation is the current activity.
  24                         For error codes, it is the exception.  For debug codes, it is not defined at this time.
  25                         Type EFI_STATUS_CODE_VALUE is defined in "Related Definitions" below.
  26                         Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.
  27
  28   @param  Instance      The enumeration of a hardware or software entity within the system.
  29                         A system may contain multiple entities that match a class/subclass pairing.
  30                         The instance differentiates between them.  An instance of 0 indicates that instance information is unavailable,
  31                         not meaningful, or not relevant.  Valid instance numbers start with 1.
  32
  33
  34   @param  CallerId      This optional parameter may be used to identify the caller.
  35                         This parameter allows the status code driver to apply different rules to different callers.
  36                         Type EFI_GUID is defined in InstallProtocolInterface() in the UEFI 2.0 Specification.
  37
  38
  39   @param  Data          This optional parameter may be used to pass additional data
  40
  41   @return               The function always return EFI_SUCCESS.
