- that that the caller is requesting, and it must match one
- of the languages specified in SupportedLanguages. The

- ControllerHandle and ChildHandle in the language specified
- by Language from the point of view of the driver specified
- by This.

- Returns:
- EFI_SUCCESS - The Unicode string for the user readable name in the

-Abstract:
-
- Our DriverBinding member functions operate on the handles
- created by the NT Bus driver.
-
- Handle(1) - WinNtIo - DevicePath(1)
-
- If a serial port is added to the system this driver creates a new handle.
- The new handle is required, since the serial device must add an UART device
- pathnode.
-
- Handle(2) - SerialIo - DevicePath(1)\UART
-
- The driver then adds a gEfiWinNtSerialPortGuid as a protocol to Handle(1).
- The instance data for this protocol is the private data used to create
- Handle(2).
-
- Handle(1) - WinNtIo - DevicePath(1) - WinNtSerialPort
-
- If the driver is unloaded Handle(2) is removed from the system and
- gEfiWinNtSerialPortGuid is removed from Handle(1).
-
- Note: Handle(1) is any handle created by the Win NT Bus driver that is passed
- into the DriverBinding member functions of this driver. This driver requires
- a Handle(1) to contain a WinNtIo protocol, a DevicePath protocol, and
- the TypeGuid in the WinNtIo must be gEfiWinNtSerialPortGuid.
-
- If Handle(1) contains a gEfiWinNtSerialPortGuid protocol then the driver is
- loaded on the device.
