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.
