performed after PS2_KEY_TMAT .
PS2_KEY_MAKE Set make-only behavior for an individual key.
The key code from scancode set 3 for the individual key is passed as the first
byte in the character buffer addressed by arg. This request can be made when
the keyboard is using any scancode set; however, it affects only the operation
of scancode set 3. Because keyboards might be left in a disabled state after
this request, the
PS2_ENABLE request should be performed after
PS2_KEY_MAKE .
PS2_KEY_MKBRK
Set make/break for an individual key.
The key code from scancode set 3 for the individual key is passed as the first
byte in the character buffer addressed by arg. Make/break behavior will be set
for this key. This request can be made when the keyboard is using any scan-
code set; however, it affects only the operation of scancode set 3. Because key-
boards might be left in a disabled state after this request, the
PS2_ENABLE
request should be performed after PS2_KEY_MKBRK
.
PS2_INDICATORS Set the state of keyboard indicators, Num Lock, Caps Lock, and Scroll Lock,
according to the value passed in the first byte of the character buffer addressed
by arg.
The indicators are bit-mapped as follows:
NONE_LED No indicators active
CAPS_LED Caps Lock indicator active
NUM_LED Num Lock indicator active
SCROLL_LED Scroll Lock indicator active
PS2_RATEDELAY Set the rate and delay for all typematic keys by specifying the value passed as
the first byte in the character buffer addressed by arg.
Bits zero through four give the rate. Bits five and six give the delay. Bit
seven (the most significant bit) is unused and should be set to zero. The delay
in milliseconds is determined by the following equation, where X is the
numeric value of bits five through six:
delay = (1+X) * 250 (+|− 20%)
The period (interval from one output key code to the next) in seconds is deter-
mined by the following equation, where Y is the numeric value of bits zero
through two, and Z is the numeric value of bits three through four:
period = (8+Y) * (2ˆZ) * 0.00417 (+|− 20%)
The typematic rate (expressed in make codes per second) is one for each period
using the above equation. The default typematic rate is 10.9 characters per
second. The default delay is 500 milliseconds.
Mouse-Specific ioctl() Requests
PS2_SAMPLERATE Set the mouse sampling rate used in stream mode by specifying the value
passed as the first byte in the character buffer addressed by arg.
Seven specific rates are supported:
SAMPLE_10 10 reports/second maximum
SAMPLE_20 20 reports/second maximum
SAMPLE_40 40 reports/second maximum
SAMPLE_60 60 reports/second maximum
SAMPLE_80 80 reports/second maximum
SAMPLE_100 100 reports/second maximum
SAMPLE_200 200 reports/second maximum
The default rate is 100 reports/second maximum. This request updates the
mouse sampling rate only in stream mode. If the mouse is in prompt mode,
this request is ignored.
PS2_PROMPTMODE Put mouse into prompt mode.
