Handle(1) - WinNtIo - DevicePath(1)\r
\r
- If a serial port is added to the system this driver creates a new handle. \r

pathnode.\r

gEfiWinNtSerialPortGuid is removed from Handle(1).\r
\r
Note: Handle(1) is any handle created by the Win NT Bus driver that is passed\r
into the DriverBinding member functions of this driver. This driver requires\r
- a Handle(1) to contain a WinNtIo protocol, a DevicePath protocol, and \r
- the TypeGuid in the WinNtIo must be gEfiWinNtSerialPortGuid. \r
- \r
- If Handle(1) contains a gEfiWinNtSerialPortGuid protocol then the driver is \r
+ a Handle(1) to contain a WinNtIo protocol, a DevicePath protocol, and\r
+ the TypeGuid in the WinNtIo must be gEfiWinNtSerialPortGuid.\r
+\r
+ If Handle(1) contains a gEfiWinNtSerialPortGuid protocol then the driver is\r
loaded on the device.\r
