#define GIO_DEADKEYMAP _IOR('k', 8, accentmap_t)
#define PIO_DEADKEYMAP _IOW('k', 9, accentmap_t)
Get/Set accent translation table ( map )
accentmap_t == struct accentmap
#define NUM_DEADKEYS 15 /* number of accent keys */
#define NUM_ACCENTCHARS 52 /* max number of accent chars */
struct acc_t {
u_char accchar;
u_char map[NUM_ACCENTCHARS][2];

***** NOTE: These 2 ioctls used by kernel only *********
#define GIO_KEYMAPENT _IOWR('k', 10, keyarg_t)
#define PIO_KEYMAPENT _IOW('k', 11, keyarg_t)
Get/Set Keyboard Translation Table Entry.
They can be retrieved and changed individually.
keyarg_t == struct keyarg
struct keyarg {
u_short keynum; // the scancode, i.e. The index in curr
ent map. NOTE: the scancode here is not the meaning of PC Hardware based sc
ancode.
struct keyent_t key; // The value
};
Please refer to the explanation of GIO_KEYMAP/PIO_KEYMAP section fo
r the type struct keyent_t. The meaning is obvious now.
---------------------------------------------------------------------------
----
#define GIO_ATTR _IOR('a', 0, int)
get current attribute. The attribute value is represented in normal
BRGBIRGB format.
---------------------------------------------------------------------------

#define GIO_COLOR _IOR('c', 0, int)
If the console specified by the ioctl(fd... is a color console, thr
return value is 1, or the value is 0.
---------------------------------------------------------------------------
---
#define CONS_CURRENT _IOR('c', 1, int)
Get video adapter type. The values are:
KD_MONO, KD_HERCULES, KD_CGA, KD_EGA, KD_VGA, KD_PC98
---------------------------------------------------------------------------
---
#define CONS_GET _IOR('c', 2, int)
Get Current Video Mode. The Values are: SW_XXXX defined below
---------------------------------------------------------------------------
---
#define CONS_IO _IO('c', 3)
Not used.
---------------------------------------------------------------------------
--
#define CONS_BLANKTIME _IOW('c', 4, int)
Set screen blank time. the default value is 5 minutes, and the max
blank time is 7 days. ScreenSaver runs only when blankrime != 0
---------------------------------------------------------------------------
---
#define CONS_SSAVER _IOW('c', 5, ssaver_t)
#define CONS_GSAVER _IOWR('c', 6, ssaver_t)
Not used
---------------------------------------------------------------------------
----
#define CONS_CURSORTYPE _IOW('c', 7, int)
Set the cursor type
if bit 0 is set, the cursor is blink.
if bit 1 is set, use the char cursor - under text mode, it is hw cu
rsor
if all cleared, the non-blink normal cursor.
---------------------------------------------------------------------------
----
#define CONS_BELLTYPE _IOW('c', 8, int)
if bit 0 is set, set bell type to visual mode, i.e. flash the scree
n instead of bell.
if bit 1 is set, set bell type to quiet mode, i.e. not bell is the
process in the background.
set bell duration and delay will reset bell type to normal.
---------------------------------------------------------------------------
----
#define CONS_HISTORY _IOW('c', 9, int)
Set console history size.
the parameter is the history buffer lines.
