70 The virtual terminal is the device that interacts with the physical
71 terminal through console drivers. On these systems, at least one
72 console driver is loaded. In other configurations, additional console
73 drivers may be enabled, such as the framebuffer console. If more than
74 1 console driver is enabled, setting this to 'y' will allow you to
75 select the console driver that will serve as the backend for the
76 virtual terminals.
