hilkbd(7) hilkbd(7)

keyboard identiﬁcation ﬁeld within the conﬁguration code.

KBD_STATUS Read the keyboard status register.

This request returns a one-byte value containing bit ﬂags specifying the state of the shift

and control keys in the

char variable to which arg points:

KBD_STAT_LEFTSHIFT The left shift key is up

KBD_STAT_RIGHTSHIFT The right shift key is up

KBD_STAT_SHIFT Both shift keys are up

KBD_STAT_CTRL The control key is up

Other bits are undeﬁned.

KBD_REPEAT_RATE

Set the keyboard auto-repeat rate.

The one-byte value to which arg points is the negative of the repeat period, in tens of mil-

liseconds. The repeat rate is the reciprocal of the repeat period. A parameter of zero dis-

ables auto-repeat.

KBD_REPEAT_DELAY

Set the keyboard auto-repeat delay.

The one-byte value to which arg points is the negative of the repeat delay, in tens of mil-

liseconds.

KBD_BEEP Cause an audible beep.

The one-byte value to which arg points speciﬁes the volume of the beep, within the range

0 through KBD_MAXVOLUME. Implementations with fewer than

KBD_MAXVOLUME

discrete levels of volume will scale the parameter into the smaller range.

ERRORS

[EINVAL] An invalid parameter was detected by

ioctl().

[EINTR] A signal was caught during a

read() system call.

[ENXIO] No keyboard is present on the HP-HIL link speciﬁed by the minor number.

[ENODEV] An attempt was made to use

write() using hilkbd.

[EBUSY] The device is already open.
