If your keyboard driver does not use the default name Kbdmouse.dll, in Platform.reg, define the keybd_driver symbol to be the name of your keyboard driver. The following example sample shows how to define the name for your keyboard driver.

#define keybd_driver  "MyKeyboardDriver.dll"

The following registry key example shows the required settings for supporting the Remote Desktop Protocol (RDP), if your keyboard driver does not support Layout Manager interface.

[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\KEYBD]
    "Keyboard Type"=dword:<type>
    "Keyboard SubType"=dword:<subtype>
    "Keyboard Function Keys"=dword:<function keys>
    "Keyboard Layout"="<input locale>"
