* Description:
* Register a console device on a framed NX window. The device will be

* Input Parameters:
* hfwnd - A handle that will be used to access the window. The window must

* wndo - Describes the window and font to be used
* minor - The device minor number
*
* Return:
* A non-NULL handle is returned on success.
