.SH NAME
operations are supported for console terminals and virtual consoles.
.TP
.B KDGETLED
-Get state of LEDs.
-.I argp
-points to a
-.IR char .
-The lower three bits
-of
-.I *argp
-are set to the state of the LEDs, as follows:
-.TS
-l l l.
-LED_CAP 0x04 caps lock led
-LED_NUM 0x02 num lock led
-LED_SCR 0x01 scroll lock led
-.TE
-.TP
+.TQ
.B KDSETLED
-Set the LEDs.
-The LEDs are set to correspond to the lower three bits of the
-unsigned long integer in
-.IR argp .
-However, if a higher order bit is set,
-the LEDs revert to normal: displaying the state of the
-keyboard functions of caps lock, num lock, and scroll lock.
-.P
-Before Linux 1.1.54, the LEDs just reflected the state of the corresponding
-keyboard flags, and KDGETLED/KDSETLED would also change the keyboard
-flags.
-Since Linux 1.1.54 the LEDs can be made to display arbitrary
-information, but by default they display the keyboard flags.
-The following two ioctls are used to access the keyboard flags.
-.TP
+.TQ
.B KDGKBLED
-Get keyboard flags CapsLock, NumLock, ScrollLock (not lights).
-.I argp
-points to a char which is set to the flag state.
-The low order three bits (mask 0x7) get the current flag state,
-and the low order bits of the next nibble (mask 0x70) get
-the default flag state.
-(Since Linux 1.1.54.)
-.TP
+.TQ
.B KDSKBLED
-Set keyboard flags CapsLock, NumLock, ScrollLock (not lights).
-.I argp
-is an unsigned long integer that has the desired flag state.
-The low order three bits (mask 0x7) have the flag state,
-and the low order bits of the next nibble (mask 0x70) have
-the default flag state.
-(Since Linux 1.1.54.)
-.TP
+.TQ
.B KDGKBTYPE
-Get keyboard type.
-This returns the value KB_101, defined as 0x02.

-Equivalent to
-.IR "ioperm(0x3b4, 0x3df\-0x3b4+1, 1)" .
-.TP
+.TQ
.B KDDISABIO
-Disable I/O to video board.
-Equivalent to
-.IR "ioperm(0x3b4, 0x3df\-0x3b4+1, 0)" .
-.TP
+.TQ
.B KDSETMODE
-Set text/graphics mode.
-.I argp

-KD_TEXT 0x00
-KD_GRAPHICS 0x01
-.TE
-.TP
+.TQ
.B KDGETMODE
-Get text/graphics mode.

.B KDMKTONE
-Generate tone of specified length.
-The lower 16 bits of the unsigned long integer in
-.I argp
-specify the period in clock cycles,
-and the upper 16 bits give the duration in msec.
-If the duration is zero, the sound is turned off.
-Control returns immediately.
-For example,
-.I argp
-= (125<<16) + 0x637 would specify
-the beep normally associated with a ctrl-G.
-(Thus since Linux 0.99pl1; broken in Linux 2.1.49-50.)
-.TP
+.TQ
.B KIOCSOUND
-Start or stop sound generation.
-The lower 16 bits of
-.I argp
-specify the period in clock cycles
-(that is,
-.I argp
-= 1193180/frequency).
-.I argp
-= 0 turns sound off.
-In either case, control returns immediately.

-.IR chardata .
-On return, the
-.I charcount

-are filled with
-the respective data for the currently loaded font, and the

+operations are supported for console terminals and virtual consoles.
+.TP
+.B KDGETLED
+Get state of LEDs.
+.I argp
+points to a

+The lower three bits
+of

+are set to the state of the LEDs, as follows:

+l l l.
+LED_CAP 0x04 caps lock led
+LED_NUM 0x02 num lock led
+LED_SCR 0x01 scroll lock led
+.TE
+.TP
+.B KDSETLED
+Set the LEDs.
+The LEDs are set to correspond to the lower three bits of the
+unsigned long integer in
+.IR argp .
+However, if a higher order bit is set,
+the LEDs revert to normal: displaying the state of the

+flags.
+Since Linux 1.1.54 the LEDs can be made to display arbitrary
+information, but by default they display the keyboard flags.
+The following two ioctls are used to access the keyboard flags.
+.TP
+.B KDGKBLED
+Get keyboard flags CapsLock, NumLock, ScrollLock (not lights).
+.I argp
+points to a char which is set to the flag state.
+The low order three bits (mask 0x7) get the current flag state,
+and the low order bits of the next nibble (mask 0x70) get
+the default flag state.
+(Since Linux 1.1.54.)
+.TP
+.B KDSKBLED
+Set keyboard flags CapsLock, NumLock, ScrollLock (not lights).
+.I argp

+The low order three bits (mask 0x7) have the flag state,
+and the low order bits of the next nibble (mask 0x70) have
+the default flag state.
+(Since Linux 1.1.54.)

+.B KDMKTONE
+Generate tone of specified length.
+The lower 16 bits of the unsigned long integer in
+.I argp
+specify the period in clock cycles,
+and the upper 16 bits give the duration in msec.
+If the duration is zero, the sound is turned off.
+Control returns immediately.
+For example,

+the beep normally associated with a ctrl-G.
+(Thus since Linux 0.99pl1; broken in Linux 2.1.49-50.)

+Start or stop sound generation.
+The lower 16 bits of
+.I argp
+specify the period in clock cycles
+(that is,
+.I argp
+= 1193180/frequency).
