/**
  Convert status code value and extended data to readable ASCII string, send string to serial I/O device.

  @param  CodeType         Indicates the type of status code being reported.
  @param  Value            Describes the current status of a hardware or software entity.
                           This included information about the class and subclass that is used to
                           classify the entity as well as an operation.
  @param  Instance         The enumeration of a hardware or software entity within
                           the system. Valid instance numbers start with 1.
  @param  CallerId         This optional parameter may be used to identify the caller.
                           This parameter allows the status code driver to apply different rules to
                           different callers.
  @param  Data             This optional parameter may be used to pass additional data.

  @retval EFI_SUCCESS      Status code reported to serial I/O successfully.
  @retval EFI_DEVICE_ERROR EFI serial device cannot work after ExitBootService() is called.
  @retval EFI_DEVICE_ERROR EFI serial device cannot work with TPL higher than TPL_CALLBACK.
