NAME

     ltem - ANSI Layered Console Driver

SYNOPSIS

     #include <sys/types.h>

     #include <fcntl.h>

     #include <visual.h>

     #include <sys/ltem.h>

DESCRIPTION

     The ltem driver provides a general-purpose ANSI interface to
     the  system  console device. ltem is a layered device driver
     which on one side provides  the  kernel  with  a  consistent
     interface to the system console device (and therefore to the
     console framebuffer) and on the other side  uses  ioctls  to
     send data to the framebuffer driver (see  visual_io(7I)).

IOCTLS

     The following  ioctl(2) calls are supported:

     VIS_CONS_MODE_CHANGE
           Notifies ltem that the resolution  of  the  underlying
           framebuffer  has  been changed. ltem will stop console
           output, notify the framebuffer (by passing this  ioctl
           on),   reset   the   terminal   emulator   (using  the
           VIS_DEVFINI and VIS_DEVINIT ioctls), and allow console
           output again.
