      NAME
           disp - Bull-SPS9 Monochrome Display

      DESCRIPTION
           /dev/disp0 through /dev/disp3 refer to Bull-SPS9 Monochrome
           displays attached to "Display" ports 1 through 4 on the
           Bull-SPS9 back panel.

           Input/output control is described in termio(7).  There are
           four ioctl(2) calls that apply to the Bull-SPS9 Monochrome
           Display only:

                #include <termio.h>
                ioctl (fildes, BCCURSON, arg)
                int arg;

           If arg is 0, the cursor will not be shown.  If arg is 1, the
           cursor will be shown at the current text location in either
           ASCII or ANSI X3.64 emulation mode.

                #include <termio.h>
                #include <sys/graf.h>
                ioctl (fildes, BCGETSZ, arg)
                struct Form *arg;

           Get the parameters associated with the display and store
           them in the Form structure referenced by arg.  The width and
           height of the display are measured in pixels and returned in
           arg -> width and arg -> height.  The base address in virtual
           memory of the display is returned in arg -> bits.

                #include <termio.h>
                ioctl (fildes, BCGETTYPE, arg)
                int *arg;

           Get the hardware type value and store it into the integer
           referenced by arg.  The currently defined values are:

                0    monochrome, 768 X 1024, V1 keyboard
                1    monochrome, 1024 X 800, V1 keyboard
                2    monochrome, 1024 X 800, V2 keyboard

                #include <termio.h>
                ioctl (fildes, BCINVRT, arg)
                int arg;

           Set the hardware video contrast according to arg.  If arg is
           0, the background will be white with black text.  If arg is
           1, the background will be black with white text.  If arg is
           anything else, the video contrast will be inverted from its
           current state.
