+Module Name:
+
+ WinNtSerialIo.c
+
+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.
