If a product edition appears with the product version, behavior is different in that product edition.

<1> Section 2: When implementing Telnet VTNT Terminal Type Format on Windows, implementers can take advantage of Windows Console APIs such as ReadConsoleOutput () API and WriteConsoleOutput() to read and write to the console screen buffer. For more information, see [MSDN-CONSOLES]. Windows also has an implementation of the console screen buffer (see [MSDN-CSB]).

<2> Section 2.1.1: Windows Telnet Server fills the Char field with Unicode UTF-16 characters.

<3> Section 2.2: Windows Telnet server expects a client to fill this field with virtual key codes that are compatible with the keyboard installed on the server. Virtual key codes for each of the keyboard keys are specified in section 2.2.1. Implementations of Telnet VTNT Terminal Type Format on Windows can use the Windows ReadConsoleInput() API, which returns a structure compatible with the INPUT_RECORD structure, with all fields including wVirtualKeyCode filled in.

<4> Section 2.2: Windows Telnet server expects a client to fill this field with the scan code. An implementation on Windows can use the ReadConsoleInput() API, which returns a structure compatible with the INPUT_RECORD structure, with all fields including wVirtualScanCode filled with the scan code of the key pressed.

<5> Section 2.2: Windows Telnet client uses Unicode characters to fill this field.
