|

<HR>
|
||||
<H2><A NAME="s1">1. Keyboard scancodes</A></H2>
|
||||
|
||||
<P>The data from a keyboard comes mainly in the form of scancodes,
|
||||
produced by key presses or used in the protocol with the computer.
|
||||
(
|
||||
<A HREF="scancodes-9.html#scancodesets">Different codes</A> are used by the keyboard
|
||||
firmware internally, and there also exist several
|
||||
<A HREF="scancodes-9.html#scancodesets">sets of scancodes</A>.
|
||||
Here in this section we only talk about the default codes - those from
|
||||
translated scancode set 2. Less common modes are discussed
|
||||
<A HREF="scancodes-9.html#scancodesets">below</A>.)
|
||||
Each key press and key release produces between 0 and 6 scancodes.
|
||||
<P>
|
||||
<H2><A NAME="ss1.1">1.1 Key release</A>
|
||||
</H2>
|
||||
|
||||
<P>Below I'll only mention the scancode for key press (`make').
|
||||
The scancode for key release (`break') is obtained from it
|
||||
by setting the high order bit (adding 0x80 = 128).
|
||||
Thus, Esc press produces scancode <B>01</B>, Esc release
|
||||
scancode <B>81</B> (hex).
|
||||
For sequences things are similar: Keypad-/ gives <B>e0</B> <B>35</B>
|
||||
when pressed, <B>e0</B> <B>b5</B> when released. Most keyboards will
|
||||
repeat the make code (key down code) when the key repeats. Some will also
|
||||
fake Shift down and Shift up events during the repeat.
|
||||
<P>The keys PrtSc/SysRq and Pause/Break are special.
|
||||
The former produces scancode <B>e0</B> <B>2a</B> <B>e0</B> <B>37</B>
|
||||
when no modifier key is pressed simultaneously, <B>e0</B> <B>37</B>
|
||||
together with Shift or Ctrl, but <B>54</B> together with (left or right) Alt.
|
||||
(And one gets the expected sequences upon release. But see
|
||||
<A HREF="scancodes-5.html#mtek">below</A>.)
|
||||
The latter produces scancode sequence
|
||||
<B>e1</B> <B>1d</B> <B>45</B> <B>e1</B> <B>9d</B> <B>c5</B>
|
||||
when pressed (without modifier) and nothing at all upon release.
|
||||
However, together with (left or right) Ctrl, one gets
|
||||
<B>e0</B> <B>46</B> <B>e0</B> <B>c6</B>,
|
||||
and again nothing at release. It does not repeat.
|
||||
<P>See
|
||||
<A HREF="#dellnoup">below</A> for a report on keys
|
||||
with a different behaviour.
|
||||
<P>There are many reports of laptops with badly debounced key-up events.
|
||||
Thus, unexpected key-up events should probably be regarded as not
|
||||
unusual, and be ignored. Another source of key-up events without
|
||||
preceding key-down can be the
|
||||
<A HREF="#fakeshifts">fake shift</A>.

|
||||
<H2><A NAME="ss1.2">1.2 Protocol scancodes</A>
|

</H2>
|
||||
|

Some are used in the communication protocol.

|
||||
<P>Three common causes for keyboard error are:
|
||||
(i) several keys pressed simultaneously,
|
||||
(ii) keyboard buffer overflow,
|
||||
(iii) parity error on the serial line used by keyboard
|
||||
and keyboard controller for communication.
|
||||
The error reported is <B>ff</B> in
|
||||
<A HREF="scancodes-9.html#scancodesets">scancode mode</A> 1,
|
||||
and <B>00</B> in scancode modes 2 and 3.
|
||||
If translation is on, both <B>00</B> and <B>ff</B>
|
||||
are translated as <B>ff</B>.
|
||||
<P>Usually these codes have the protocol meaning. However,
|
||||
they also occur as actual scancodes, especially when
|
||||
prefixed by <B>e0</B>.
|
||||
<P>
|
||||
<H2><A NAME="ss1.3">1.3 Escape scancodes</A>
|
||||
</H2>
|
||||
|
||||
<P>The codes <B>e0</B> and <B>e1</B> introduce scancode sequences,
|
||||
and are not usually used as isolated scancodes themselves
|
||||
(but see
|
||||
<A HREF="scancodes-6.html#e0_as_key">below</A>).
|
||||
<P>(The prefix <B>e0</B> was originally used for the grey duplicates
|
||||
of keys on the original PC/XT keyboard. These days <B>e0</B> is
|
||||
just used to expand code space. The prefix <B>e1</B> used for
|
||||
Pause/Break indicated that this key sends the make/break sequence
|
||||
at make time, and does nothing upon release.)
|
||||
<P>This, and the above, means that the values
|
||||
<B>00</B>, <B>60</B>, <B>61</B>, <B>6e</B>, <B>71</B>,
|
||||
<B>7a</B>, <B>7c</B>, <B>7e</B>, <B>7f</B>
|
||||
are unavailable to signify key presses (on a default keyboard).
|
||||
Nevertheless they also occur as scancodes, see for example the
|
||||
<A HREF="scancodes-2.html#telerate">Telerate</A> and
|
||||
<A HREF="scancodes-5.html#safeway23">Safeway SW23</A> keyboards below.
|
||||
<P>Also other prefixes occur, see
|
||||
<A HREF="scancodes-5.html#prefix_80">below</A>.
|
||||
<P>
|
||||
<A HREF="scancodes-9.html#logiteche2">Logitech</A> uses an <B>e2</B> prefix
|
||||
for the codes sent by a pointing device integrated on the keyboard.
|

|

<H2><A NAME="ss1.4">1.4 Ordinary scancodes</A>

<P>The scancodes in translated scancode set 2 are given in hex.

Between parentheses the keycap on a US keyboard.

The scancodes are given in order, grouped according

<H2><A NAME="fakeshifts"></A> <A NAME="ss1.6">1.6 Fake shifts</A>
|
||||
</H2>
|
||||
|
||||
<P>The ten grey keys Insert, Home, PgUp, Delete, End, PgDn,
|
||||
Up, Left, Down, Right are supposed to function regardless
|
||||
of the state of Shift and NumLock keys. But for an old AT keyboard
|
||||
the keypad keys would produce digits when Numlock was on or Shift
|
||||
was down. Therefore, in order to fool old programs,
|
||||
fake scancodes are sent: when LShift is down, and Insert is
|
||||
pressed, <B>e0</B> <B>aa</B> <B>e0</B> <B>52</B> is sent;
|
||||
upon release of Insert <B>e0</B> <B>d2</B> <B>e0</B> <B>2a</B>
|
||||
is sent. In other words, a fake LShift-up and
|
||||
fake LShift-down are inserted.
|
||||
<P>If the Shift key is released earlier than the repeated key,
|
||||
then a real Shift-up code occurs (without preceding fake Shift-down)
|
||||
so that a program ignoring <B>e0</B> would see one more Shift-up
|
||||
than Shift-down.
|
||||
<P>When NumLock is on, no fake Shifts are sent when Shift was down,
|
||||
but fake Shifts are sent when Shift was not down. Thus,
|
||||
with Numlock, if Insert is pressed,
|
||||
<B>e0</B> <B>2a</B> <B>e0</B> <B>52</B> is sent
|
||||
and upon release <B>e0</B> <B>d2</B> <B>e0</B> <B>aa</B> is sent.
|
||||
The keyboard maintains a private NumLock mode, toggled when
|
||||
NumLock is pressed, and set when the NumLock LED is set.
|
||||
<P>In the same way, when Shift is down, the Grey-/ key produces
|
||||
fake Shift-up and fake Shift-down sequences. However, it does
|
||||
not react to the state of NumLock. The purpose of course is to
|
||||
fool programs that identify Grey-/ with ordinary /, so that they
|
||||
don't treat Shift-Grey-/ like Shift-/, i.e., ?.
|
||||
<P>On a Toshiba notebook, the three Windows keys are treated like
|
||||
the group of ten keys mentioned, and get fake shifts when
|
||||
(left or right) Shift is down. They do not react to NumLock.
|
||||

<B>3b</B>, ..., <B>58</B>, and F13, ..., F24 send the same codes
|
||||
together with the LShift code <B>2a</B>.

Thus, F13 gives <B>2a</B> <B>3b</B> on press,
|

and <B>bb</B> <B>aa</B> on release.
|

Similarly, there are keys with added LCtrl code <B>1d</B>.

<P>A user program can talk to the keyboard controller on the motherboard.
|

The keyboard controller can again talk to the keyboard.
|

<P>When a key is pressed the keyboard sends the corresponding
|

keyboard scancode to the keyboard controller, and the keyboard controller
|

translates that and interrupts the CPU, allowing the CPU to read the result.
|
||||
<P>More detailed: when a key is pressed, the keyboard sends
|
||||
a start bit (low), followed by 8 data bits for the keyboard scancode
|
||||
of the key (least significant first), followed by an odd parity bit,
|
||||
followed by a stop bit (high).
|

The keyboard controller reads the data and checks the parity.

If incorrect, retransmission is requested. If incorrect again
|

a parity error is reported.

If the time between request to send and start of transmission is greater

than 15 ms, or if the eleven bits are not received within 2ms,

a timeout is reported.

In both cases (parity error or timeout), the data byte is set to 0xff.

<P>The keyboard controller has three 8-bit registers involved in

communication with the CPU: its input buffer, that can be written
|

by the CPU by writing port 0x60 or port 0x64; its output buffer,
|

that can be read by the CPU by reading from port 0x60; and the
|

status register, that can be read by the CPU by reading from port 0x64.
|

<P>If the CPU writes to port 0x64, the byte is interpreted as a command byte.
|

If the CPU writes to port 0x60, the byte is interpreted as a data byte.

On the other hand, Synaptics (see
|

<A HREF="http://www.synaptics-uk.com/decaf/utilities/ps2-mux.PDF">ps2-mux.PDF</A>)
|
||||
uses this command as a handshake between driver and controller:
|
||||
if the driver gives this command three times, with data bytes
|
||||
0xf0, 0x56, 0xa4 respectively, and reads 0xf0, 0x56, but not 0xa4
|
||||
back from the mouse output buffer, then the driver knows that the
|
||||
controller supports Synaptics AUX port multiplexing, and the controller
|
||||
knows that it does not have to do the usual data faking and goes
|
||||
into multiplexed mode. The third byte read is the version of the
|
||||
Synaptics standard.
|
||||
<P>There is a corresponding deactivation sequence, namely
|
||||
0xf0, 0x56, 0xa5. (And again the last byte is changed to the
|
||||
version number of the standard supported.)
|
||||
This latter sequence works both in multiplexed mode and in legacy mode
|

and can thus be used to determine whether this feature is present
|

without activating it.

<P>See also the multiplexer commands

<P>For some laptops it has been reported that bit 3 of every third

mouse byte is forced to 1 (as it would be with the standard
|
||||
3-byte mouse packets). This may turn 0xf0, 0x56, 0xa4 into

||||
0xf0, 0x56, 0xac and cause misdetection of Synaptics multiplexing

||||
(for version 10.12).

|

|
||||
<P>One can not only talk to the keyboard controller (by writing to
|
||||
port 0x64), but also to the keyboard (by writing to port 0x60).
|
||||
<P>In order to avoid interference between scancode sequences or
|
||||
mouse packets and the reponses given to commands, the keyboard
|
||||
or mouse should always be disabled before giving a command that
|
||||
requires a response, and probably enabled afterwards.
|
||||
Some keyboards or mice do the disable automatically in this
|
||||
situation, but still require an explicit enable afterwards.
|
||||
<P>Each command (other than 0xfe) is ACKed by 0xfa.
|
||||
Each unknown command is NACKed by 0xfe.
|
||||
Some mice expect a corrected byte as reply to the 0xfe,
|
||||
and will double-NACK with 0xfc when also that is wrong.
|
||||
<P>Here a list with the common commands.

<P>Mice come in various flavours - serial mice, PS/2 mice, busmice, USB mice.
|
||||
Below a little about mice using the PS/2 protocol, since these also use
|
||||
the keyboard controller.
|
||||
<P>A mouse has a number of buttons (1-5 is common) and must report
|
||||
button presses. It has some way of detecting motion, and must report
|
||||
the amount of movement in the X and Y direction, usually as differences
|
||||
with the previously reported position, in a (dx,dy) pair.
|
||||
Touchpads can also report absolute position.
|
||||
<P>Reports come in the form of mouse packets of between 1 and 8 bytes.
|
||||
Various protocols are in use.

<P>A PS/2 mouse can be in <I>stream mode</I> (the default).
|
||||
In this mode it produces a stream of packets indicating mouse movements
|
||||
and button presses. Or it can be in <I>remote mode</I>.
|
||||
In this mode the mouse only sends a packet when the host
|
||||
requests one, using the <B>
|
||||
<A HREF="#mceb">eb</A></B> command.
|
||||
Finally, it can be in <I>echo</I> ("wrap") <I>mode</I>,
|
||||
in which everything the host sends is echoed back, until
|
||||
either a reset (<B>ff</B>) or clear echo mode (<B>ec</B>)

is received.

|

|

<P>For more advanced mouse modes it is necessary to send data to the mouse.
|
||||
There is now a commonly accepted way.
|
||||
<P>First Logitech tried to use the <B>d1</B> command followed by an
|
||||
arbitrary data sequence.
|
||||
While the IBM specs reserve <B>d1</B>-<B>df</B> for vendor unique commands,
|
||||
it turns out that not all BIOSes will transmit such codes.
|
||||
So Logitech drops the <B>d1</B> and uses the sequence
|
||||
<B>e8</B> <I>aa</I> <B>e8</B> <I>bb</I> <B>e8</B> <I>cc</I>
|
||||
<B>e8</B> <I>dd</I> to transmit the byte <I>aabbccdd</I>, where
|
||||
<I>aa</I>, <I>bb</I>, <I>cc</I>, <I>dd</I> are 2-bit quantities.
|
||||
In this way an arbitrarily long sequence of bytes can be transmitted.
|
||||
<P>For synchronization purposes it is possible to separate such groups
|
||||
of four <B>e8</B> commands by an <B>e6</B> command.
|
||||
Indeed, such separation may be required: Synaptics Touchpads react to
|
||||
<B>e9</B> or <B>f3</B> commands preceded by precisely four
|
||||
<B>e8</B> commands.
|
||||
<P>
|
||||
<H3>Magic knock</H3>
|
||||
|
||||
<P>For example, the "magic knock" <B>d1</B> <B>39</B> <B>db</B>
|
||||
that sets a device that understands it in PS/2++ mode,
|
||||
becomes <B>e8</B> <B>00</B> <B>e8</B> <B>03</B>

<B>e8</B> <B>02</B> <B>e8</B> <B>01</B> <B>e6</B>

<B>e8</B> <B>02</B> <B>e8</B> <B>03</B>,
|
||||
abbreviated {E8}0321 {E6} {E8}3123.
|
||||
Note that 0321 and 3123 do not have repeated symbols. If they had,
|
||||
too intelligent intermediate hardware transmitting these sequences
|
||||
might see a superfluous command and suppress it.

<P>When preceded by an 8-bit request number encoded via four <B>e8</B>
|
||||
commands, the <B>
|
||||
<A HREF="#mcf3">f3</A></B> <B>14</B>
|
||||
(set sample rate 20) command sets the mode byte to the
|
||||
encoded number. (Thus on Touchpads 4.x. Older models have more mode
|
||||
bytes and several such commands.)

<P>
|

<H2><A NAME="ss12.7">12.7 Vendor extensions</A>
|
||||
</H2>
|
||||
|
||||
<P>There is a complicated forest of "magic sequences" that enable
|
||||
vendor extensions. Recognizing all of these is a very obscure activity.
|
||||
<P>(Moreover, recognizing these may be counterproductive:
|
||||
if the mouse has special capabilities which are activated
|
||||
by a special sequence, and it is connected to the computer
|
||||
via a KVM switch that does not know about this special protocol,
|
||||
then switching away and back will leave the mouse in the non-special
|
||||
state. This leads to non-functioning mice.)
|
||||
<P>A 2002 Logitech file describes the following procedure for recognizing
|
||||
the mouse type:
|
||||
<P>Stage 1: Send <B>ff</B>: reset.
|
||||
The reply is ignored. (Most common is <B>aa</B> <B>00</B>.)
|
||||
<P>Stage 2: Send <B>f3</B> <B>0a</B> <B>f2</B>: set sample rate
|
||||
and ask for ID. If the reply is <B>02</B>, we have a trackball -
|
||||
it has its own protocol. (The usual reply is <B>00</B>.)
|
||||
<P>Stage 3: Send <B>e8</B> <B>00</B> <B>e6</B> <B>e6</B> <B>e6</B>
|
||||
<B>e9</B>: set resolution and scaling (three times), and request status.
|
||||
The reply consists of three bytes <I>s1</I> <I>s2</I> <I>s3</I>.
|
||||
An old-fashioned mouse would report 0 in the second status byte <I>s2</I>
|
||||
(since that is the resolution and we just set it).
|
||||
<P>If <I>s2</I> is nonzero then: <I>s2</I> is the number of buttons,
|
||||
<I>s3</I> is the firmware revision,
|
||||
<I>s1</I> has the firmware ID (device type) bits 6-0 in bits 3-0,6-4,
|
||||
while bit 7 of s1 indicates support for the
|
||||
<B>e7</B> <B>e7</B> <B>e7</B> <B>e9</B> command.
|
||||
<P>If <I>s1</I>=<B>d0</B> and <I>s2</I>=<B>03</B> and
|
||||
<I>s3</I>=<B>c8</B>, suspect Synaptics.
|
||||
<P>If <I>s1</I> and <I>s2</I> are zero but <I>s3</I> equals <B>0a</B>,
|
||||
suspect Alps. (<I>s3</I>=<B>0a</B> is as expected, but <I>s1</I>=0
|
||||
is not)
|
||||
<P>Stage 4: If bit 7 of <I>s1</I> is set, or if we suspect Alps,
|
||||
send <B>e8</B> <B>00</B> <B>e7</B> <B>e7</B> <B>e7</B> <B>e9</B>:
|
||||
set resolution and scaling (three times), and request status.
|
||||
The reply consists of three bytes <I>t1</I> <I>t2</I> <I>t3</I>.
|
||||
Of course, we already know that this is not an old-fashioned mouse.
|
||||
<P>If <I>t2</I>=<B>01</B> and FirmwareID < 0x10 and
|
||||
<I>t1</I> >> 6 = 1, then conclude that we have a
|
||||
Cordless MouseMan (RA12).
|
||||
<P>If <I>t2</I>=<B>01</B> and FirmwareID < 0x10 and
|
||||
<I>t1</I> >> 6 = 3, then conclude that we have a
|
||||
Cordless MouseMan (RB24).
|
||||
<P>Other cases with <I>t2</I>=<B>01</B> are for new cordless mice.
|
||||
<P>If we suspect Synaptics and <I>t2</I>=0 and <I>t3</I>=<B>0a</B>,
|
||||
then conclude that we have a Synaptics touchpad.
|
||||
<P>If we suspect Alps and <I>t1</I>=<B>33</B>, then conclude that
|
||||
we have an Alps touchpad.
|
||||
<P>Stage 5: If we don't know the type yet, send <B>f3</B> <B>c8</B>
|
||||
<B>f3</B> <B>64</B> <B>f3</B> <B>50</B> <B>f2</B>:
|
||||
Set sampling rate to 200, 100, 80 Hz, and ask for ID.
|
||||
The reply is a single byte.
|
||||
If we get 3, conclude that we have an IntelliMouse.
|
||||
(And this sequence is the initialization sequence for the IntelliMouse.)
|
||||
<P>Stage 6: Send <B>ff</B>: reset. Now the device is no longer in any
|
||||
special state.
|
||||
<P>Stage 7: If we don't know the type yet, send <B>e8</B> <B>00</B>
|
||||
<B>e8</B> <B>00</B> <B>e8</B> <B>00</B> <B>e8</B> <B>00</B>
|
||||
<B>e9</B>: set resolution to 0 (four times), and ask for status.
|
||||
The reply consists of three bytes <I>u1</I> <I>u2</I> <I>u3</I>.
|
||||
If <I>u2</I>=<B>47</B> and <I>u3</I>=<B>13</B>, then conclude
|
||||
that we have a new Synaptics touchpad.
|
||||
<P>Stage 7a: At this point we can narrow down to model type.
|
||||
If the thing is Synaptics or Alps, then Logitech is no longer interested.
|
||||
If it has 3 buttons, FirmwareID 1 and firmware revision <B>50</B>,
|
||||
then conclude that it is a Logitech Mouseman.
|
||||
<P>Stage 8: If we think it is a touchpad, detect whether it has programmable RAM.
|
||||
Send <B>e6</B> <B>e8</B> <B>00</B> <B>e8</B> <B>00</B> <B>e8</B>
|
||||
<B>00</B> <B>e8</B> <B>00</B> <B>e9</B>. The reply consists of three
|
||||
bytes <I>v1</I> <I>v2</I> <I>v3</I>.
|
||||
If <I>v1</I>=<B>06</B> and <I>v2</I>=<B>00</B>, then conclude
|
||||
that we have a Touchpad TP3 with programmable RAM.
|
||||
<P>Stage 9: Test whether the device understands the Logitech PS/2++ protocol.
|
||||
Send the "magic knock" <B>f5</B> <B>e8</B> <B>00</B> <B>e8</B>
|
||||
<B>03</B> <B>e8</B> <B>02</B> <B>e8</B> <B>01</B> <B>e6</B>
|
||||
<B>e8</B> <B>03</B> <B>e8</B> <B>01</B> <B>e8</B> <B>02</B>
|
||||
<B>e8</B> <B>03</B> <B>f4</B>.
|
||||
Check whether the device replies with an extended report.

|

|

<P><I>First keyboards with an XT interface.
|
||||
There is no keyboard controller, no commands to the keyboard.
|
||||
On a modern computer these will usually yield "keyboard error"
|
||||
or "KB/interface error" or some such, but sometimes they can be
|
||||
used nevertheless.</I>
|
||||
<P>The IBM PC (all models) and the IBM XT (models 68, 78, 86, 87, 88,
|
||||
267, 277) came with this 83-key keyboard.
|
||||
The IBM AT (models 68, 99, 239, 319) came with an 84-key keyboard.
|
||||
The IBM XT (models 89, 268, 278, 286) and the IBM AT model 339
|
||||
came with a 101-key keyboard.
|
||||
<P>The original IBM 83-key PC/XT keyboard did not have LEDs.
|
||||
The original IBM 84-key AT keyboard has LEDs, separates the
|
||||
keypad from the main area, moves the Esc key to the right,

and adds the SysReq key.
|

The original IBM 101-key keyboard moves the ten function keys
|
||||
from the left to the top row and adds two more. The Esc key is moved
|
||||
in front of this row of function keys. The "number" and "cursor"
|
||||
functions of the keypad are separated. There are duplicate Ctrl and Alt
|
||||
keys.

The Olivetti M24 (also sold under the names Logabax 1600 and
|

ATT PC-6300) was an IBM compatible manufactured in 1984.

<P>John Elliott writes:
|
||||
The Olivetti M24 is an XT sort-of clone. It
|
||||
has two possible keyboards - the normal (83-key) IBM one,
|
||||
and a "deluxe" one (102 keys) with 18 function keys.
|
||||
<P>Unlike a normal XT keyboard, it is possible to send commands to it.
|
||||
The BIOS does this twice:
|
||||
(1) Command 01h makes the keyboard perform a self-test.
|
||||
(2) Command 05h makes the keyboard return a 1-byte ID. The least signficant
|
||||
bit is set for a "deluxe" layout.
|
||||
<P>The keyboard connector is DE-9 rather than DIN. Pins are:
|
||||
<PRE>
|
||||
1 KBDATA
|
||||
2 KBCLOCK
|
||||
3 GND
|

4 GND

8 TEST0

|
||||
|

(pins 6-9 are not used by the supplied keyboards).
|
||||
<P>Attached
|
||||
<A HREF="m24kbd.png">the diagram</A>
|
||||
of the 'deluxe' keyboard, which shows its scancodes in decimal.
|
||||
<P>A mouse can be attached to the keyboard. The following is based
|
||||
on disassembling attmouse.drv from Windows 1.0.
|
||||
<P>Windows initialises the mouse by sending the following bytes to the
|
||||
keyboard: 0x12, 0x77, 0x78, 0x79, 0x00.
|
||||
The 0x12 is almost certainly a command byte; 0x77, 0x78 and 0x79 are the
|
||||
scancodes to be returned by the three mouse buttons. I don't know what the
|
||||
0x00 is for.
|
||||
<P>It then handles the following scancodes:
|
||||
0xFE -- mouse movement. The next two scancodes are delta X, then delta Y,
|
||||
in ones' complement.
|
||||
0x77, 0x78, 0x79 (and 0xF7, 0xF8, 0xF9) -- button presses / releases.
|
||||
<P>When shutting down the mouse, it sends these bytes to the keyboard:
|
||||
0x11, 0x1C, 0x53, 0x01, 0x4B, 0x4D, 0x48, 0x50, 0x02, 0x04.
|
||||
My guesses here are:
|
||||
0x11: Mouse movement becomes simulated keypresses.
|
||||
0x1C, 0x53, 0x01: Scancodes to be returned by mouse button presses.
|
||||
0x4B, 0x4D, 0x48, 0x50: Scancodes to be returned by mouse movement.
|
||||
0x02, 0x04: Don't know.

is entirely incompatible with XT and AT keyboards, and can be used only

on an Amstrad; conversely, no other keyboard will work on an older Amstrad.
|

This keyboard has a Del key on the keypad, and both Del-> and Del<- keys

|

Left of the Enter key a PrtSc/* key.

<P>The above only mentions the PC1512/PC1640 style of keyboard.

Later Amstrad XTs (PPC512, PPC640, PC20, PC200, PC2086, PC3086) used a
|
||||
102-key keyboard with the same layout and scancodes as a normal 102-key XT
|
||||
keyboard. This design is not only incompatible with normal XT and AT
|
||||
keyboards, it's also incompatible with the PC1512 keyboard. The joystick
|
||||
socket is no longer present, but mouse button clicks are still handled by
|
||||
the keyboard, with the same scancodes <B>7d</B> (right button) and
|
||||
<B>7e</B> (left button).
|
||||
<P>On the PPC512, PPC640, PC20 and PC200, the keyboard is in the same box as
|
||||
the motherboard, and is connected directly to it by ribbon cable.

<P><I>I recently came into possession of a 97-key keyboard with Japanese

markings on the keys. (The keys also have the standard

qwerty-characters on them, with the exception of some of the meta-keys
|
||||
(there are 3 keys near the Alt keys on either side of the spacebar with
|
||||
only Japanese characters on them so I don't know what they are).
|
||||
In any case, the keyboard sends out scancodes that work for all the main
|
||||
keys (backspace, letters and numbers, enter, shift), but the numeric
|
||||
keypad, Alt keys, and function keys don't work.
|
||||
I have run the board through <CODE>showkey -s</CODE>, so I know what
|
||||
scancodes this keyboard sends out.
|
||||
However, the F9 and F10 keys send out <B>60</B> and <B>61</B>,
|
||||
respectively, so their key release events send out <B>e0</B>
|
||||
and <B>e1</B>, confusing the keyboard driver.</I>

<P>ASCII and JIS-Roman differ in two or three points: the code positions
|

where ASCII has backslash, tilde, broken bar,
|

JIS-Roman uses yen, overbar and vertical bar, respectively.
|
||||
<P>Some keyboards have the tilde printed on the keycap for the 0 key, some don't.
|
||||
Similarly, some keyboards have the backslash printed on the keycap for the _ key
|
||||
and some don't, but in all cases you need Shift to get _.

<P>Norman Diamond adds to the previous section:
|

<P><I>To the left of the spacebar,</I>
|
||||
(Shift-JIS) <20><><EFBFBD>ϊ<EFBFBD>
|
||||
<I>(muhenkan) means no conversion
|
||||
from kana to kanji. To the right of the spacebar,
|
||||
<EFBFBD>ϊ<EFBFBD>
|
||||
(henkan) means conversion from kana to kanji. In Microsoft systems
|
||||
it converts the most recently input sequence of kana to the system's
|
||||
first guess at a string of kanji/kana/etc. with the correct pronunciation
|
||||
and a guess at the meaning. Repeated keypresses change it to other
|
||||
possible guesses which are either less common or less recently used,
|
||||
depending on the situation. The shifted version of this key is
|
||||
<EFBFBD>O<EFBFBD><EFBFBD><EFBFBD><EFBFBD>
|
||||
(zenkouho) which means "previous candidate" -- "zen" means "previous",
|
||||
while "kouho" means "candidate"</I> (explanation courtesy of NIIBE Yutaka)
|
||||
<I>-- it rotates back to earlier guesses for kanji conversion.
|
||||
The alt version of this key is
|
||||
<EFBFBD>S<EFBFBD><EFBFBD><EFBFBD><EFBFBD>
|
||||
also pronounced (zenkouho), which means "all candidates" -- here,
|
||||
"zen" means "all" -- it displays a menu of all known guesses.
|
||||
I never use the latter two functions of the key, because after
|
||||
pushing the henkan key about three times and not getting the desired guess,
|
||||
it displays a menu of all known guesses anyway.</I>
|
||||
<P><I>Next on the right,
|
||||
<EFBFBD>Ђ炪<EFBFBD><EFBFBD>
|
||||
(hiragana) means that
|
||||
phonetic input uses one conventional Japanese phonetic alphabet,
|
||||
which of course can be converted to kanji by pressing the henkan key later.
|
||||
The shifted version is
|
||||
<EFBFBD>J<EFBFBD>^<5E>J<EFBFBD>i
|
||||
(katakana) which means the other Japanese phonetic alphabet,
|
||||
and the alt version is
|
||||
<EFBFBD><EFBFBD><EFBFBD>[<5B>}<7D><>
|
||||
(ro-maji) which means the Roman alphabet.</I>
|
||||
<P><I>Near the upper left,
|
||||
<EFBFBD><EFBFBD>/<2F>S
|
||||
(han/zen) means switch between hankaku
|
||||
(half-size, the same size as an ASCII character) and zenkaku
|
||||
(full-size, since the amount of space occupied by a kanji
|
||||
is approximately a square, twice as fat as an ASCII character).
|
||||
It only affects katakana and a few other characters
|
||||
(for example there's a full-width copy of each ASCII character
|
||||
in addition to the single-byte half-width encodings).
|
||||
The alt version of this is
|
||||
<EFBFBD><EFBFBD><EFBFBD><EFBFBD>
|
||||
(kanji) which
|
||||
actually causes typed Roman phonetic keys to be displayed as Japanese
|
||||
phonetic kana (either hiragana or katakana depending on one of the other
|
||||
keys described above) and doesn't cause conversion to kanji.</I>

</H2>
|

|

<P>John Bradford reports that he has a Japanese keyboard
|
||||
(an IBM 5576 KEYBOARD-2, part number 94X1110) that by default
|
||||
simulates US key layout. Thus, pressing the @ key yields scancodes
|
||||
<B>2a</B> <B>03</B> (fake shift followed by digit 2),
|
||||
pressing Shift - yields scancodes <B>b6</B> <B>0d</B>
|
||||
(fake shift down, =) with release <B>8d</B> <B>36</B>, etc.
|
||||
<P>Thus, the (translated Set 2) scancodes can be read off the
|
||||
<A HREF="#japusdiffs">table</A> with differences between the
|
||||
Japanese and the US layout.
|
||||
<P>In this state the non-ASCII keys (Yen and overline) yield an error
|
||||
(<B>ff</B>). The Japanese keys hankaku, kanji/katakana, muhenkan,
|

zenkoho/henkan, hiragana, zenmen ki, yield the codes expected from
|

keys in that position on a US keyboard: <B>29</B> (`/~),
|

<B>38</B> (LAlt), <B>39</B> (space), <B>39</B> (space),
|

<B>39</B> (space), <B>e0</B> <B>38</B> (RAlt), respectively.
|

<P>Switching the keyboard to Set 3 enables the Japanese keys.
|
||||
In untranslated Set 3 these give codes: hankaku <B>0e</B>,
|
||||
Yen <B>13</B>, overline (shift ^), kanji/katakana <B>19</B>,
|

muhenkan <B>85</B>, zenkoho/henkan <B>86</B>,

(Also: backslash/underscore <B>5c</B>, bracketright/braceright <B>53</B>.)
|

<P>This is the only keyboard I know that gives more information in Set 3
|
||||
than in Set 2. It reports

<P>The Korean keyboard has two keys, the Korean/Chinese
|

and the Korean/English toggles, that generate scancodes
|

<B>f1</B> and <B>f2</B> (respectively) when pressed,
|

and nothing when released. They do not repeat.
|

The keycaps are "hancha" and "han/yong" (written in Hangul).
|

Hancha (hanja) means Chinese character, and Han/Yong is short for
|

Hangul/Yongcha (Korean/English).

They are located left and right of the space bar.

<P>
|

<H2><A NAME="ss9.1">9.1 Three scancode sets</A>
|
||||
</H2>
|
||||
|
||||
<P>The usual PC keyboards are capable of producing three sets of scancodes.
|
||||
Writing 0xf0 followed by 1, 2 or 3 to port 0x60 will put the keyboard
|
||||
in scancode mode 1, 2 or 3. Writing 0xf0 followed by 0 queries the mode,
|
||||
resulting in a scancode byte <B>43</B>, <B>41</B> or <B>3f</B>
|
||||
from the keyboard.
|
||||
<P>Set 1 contains the values that the XT keyboard (with only one set
|
||||
of scancodes) produced, with extensions for new keys. Someone
|
||||
decided that another numbering was more logical and invented
|
||||
scancode Set 2. However, it was realized that new scancodes
|
||||
would break old programs, so the keyboard output was fed to a
|
||||
8042 microprocessor on the motherboard that could translate Set 2
|
||||
back into Set 1. Indeed a smart construction. This is the default today.
|
||||
Finally there is the PS/2 version, Set 3, more regular, but used by
|
||||
almost nobody.
|
||||
<P>(I wrote this long ago. Nowadays Linux 2.5 may try to use Set 3.
|
||||
Also certain HP machines, like the PS/2 version of the HP9000
|
||||
workstation, have used Set 3.)
|
||||
<P>Sets 2 and 3 are designed to be translated by the 8042.
|
||||
Set 1 should not be translated.
|
||||
<P>Not all keyboards support all scancode sets. For example, my MyCom
|
||||
laptop only supports scancode Set 2, and its keyboard does not react
|
||||
at all when in mode 1 or 3.
|
||||
<P>
|
||||
<H2><A NAME="ss9.2">9.2 Make and Break codes</A>
|
||||
</H2>
|
||||
|
||||
<P>The key press / key release is coded as follows:
|
||||
<P>For Set 1, if the make code of a key is <I>c</I>, the break code
|
||||
will be <I>c</I>+0x80. If the make code is <B>e0</B> <I>c</I>,
|
||||
the break code will be <B>e0</B> <I>c</I>+0x80.
|
||||
The Pause key has make code <B>e1</B> <B>1d</B> <B>45</B>
|
||||
<B>e1</B> <B>9d</B> <B>c5</B> and does not generate a break code.
|
||||
<P>For Set 2, if the make code of a key is <I>c</I>, the break code
|
||||
will be <B>f0</B> <I>c</I>. If the make code is <B>e0</B> <I>c</I>,
|
||||
the break code will be <B>e0</B> <B>f0</B> <I>c</I>.
|
||||
The Pause key has the 8-byte make code <B>e1</B> <B>14</B> <B>77</B>
|
||||
<B>e1</B> <B>f0</B> <B>14</B> <B>f0</B> <B>77</B>.
|
||||
<P>For Set 3, by default most keys do not generate a break code - only CapsLock,
|
||||
LShift, RShift, LCtrl and LAlt do. However, by default all non-traditional
|
||||
keys do generate a break code - thus, LWin, RWin, Menu do, and for example
|
||||
on the Microsoft Internet keyboard, so do Back, Forward, Stop,
|
||||
Mail, Search, Favorites, Web/Home, MyComputer, Calculator, Sleep.
|
||||
On my BTC keyboard, also the Macro key does.
|
||||
<P>In Scancode Mode 3 it is possible to enable or disable key repeat
|
||||
and the production of break codes either on a key-by-key basis
|
||||
or for all keys at once.
|
||||
And just like for Set 2, key release is indicated by a <B>f0</B> prefix
|
||||
in those cases where it is indicated.
|
||||
There is nothing special with the Pause key in scancode mode 3.
|
||||
<P>
|
||||
<H2><A NAME="ss9.3">9.3 Translation</A>
|
||||
</H2>
|
||||
|
||||
<P>The 8042 microprocessor translates the incoming byte stream produced
|
||||
by the keyboard, and turns an <B>f0</B> prefix into an OR with
|
||||
<B>80</B> for the next byte.
|
||||
<A NAME="contagious"></A>
|
||||
(Some implementations do this for the next byte that does not have
|
||||
this bit set already. A consequence is that in Set 3 the keys with Set-3
|
||||
value 0x80 or more are broken in a peculiar way: hitting such a key and
|
||||
then some other key turns the make code for this last key into a break code.
|
||||
For example the Sleep key on a Microsoft Internet keyboard generates
|
||||
<B>54</B> / <B>d4</B> for press/release. But pressing and
|
||||
releasing first Menu and then Sleep produces
|
||||
<B>8d</B> <B>8d</B> <B>d4</B> <B>d4</B> as translation of
|
||||
<B>8d</B> <B>f0</B> <B>8d</B> <B>54</B> <B>f0</B> <B>54</B>.
|
||||
Other implementations are OK.)
|
||||
<P>
|
||||
<A NAME="translationtable"></A>
|
||||
Unless told not to translate, the keyboard controller translates
|
||||
keyboard scancodes into the scancodes it returns to the CPU
|
||||
using the following table (in hex):

<P>A reference for the first half of this table is the book by Gary J Konzak
|
||||
<I>PC 8042 Controller</I>, ISBN 0-929392-21-3.
|
||||
(Report by <CODE>vojtech@suse.cz</CODE>.)
|
||||
<P>A way to check this table is: (i) put the keyboard in untranslated modes
|
||||
1, 2, 3 and look at the
|
||||
<A HREF="table.h">resulting values</A>,
|
||||
and (ii) put the keyboard in translated scancode modes 1, 2, 3. Now compare
|
||||
the values. The entries with question marks were not checked in this way.
|
||||
<P>Note that the range <B>01</B>-<B>7f</B> of this table is 1-1.
|
||||
In the second half of the table, translated and untranslated values
|
||||
are equal in all known cases, with the two exceptions <B>83</B> and <B>84</B>.
|
||||
<P>One asks the controller to transmit untranslated scancodes by writing
|
||||
a keyboard controller command with bit 5 set and bit 6 cleared.
|
||||
E.g., use the command byte <B>45</B> to get translated codes,
|
||||
and <B>24</B> to get untranslated codes that do not cause interrupts.

<P>

<H3>Origin of strange scan code set values</H3>
|
||||
|
||||
<P>The keyboard command <B>f0</B> with argument 1, 2 or 3
|
||||
sets the current scancode set, and this same command
|
||||
with argument 0 asks for the current scancode set.
|
||||
The reply is <B>43</B>, <B>41</B> or <B>3f</B>
|
||||
for sets 1, 2, 3. Why? Because in reality the reply is 1, 2 or 3,
|
||||
and that is what one sees when translation is off. But translation
|
||||
turns these into <B>43</B>, <B>41</B>, <B>3f</B>.
|
||||
<P>
|
||||
<H3><A NAME="keyboardid"></A> Keyboard IDs</H3>
|
||||
|
||||
<P>Keyboards do report an ID as a reply to the command
|
||||
<B>
|
||||
<A HREF="scancodes-11.html#kcf2">f2</A></B>.
|
||||
(An XT keyboard does not reply, an AT keyboard only replies with an ACK.)
|
||||
An MF2 AT keyboard reports ID <B>ab</B> <B>83</B>.
|
||||
Translation turns this into <B>ab</B> <B>41</B>.
|
||||
<P>Many short keyboards, like IBM ThinkPads, and Spacesaver keyboards,
|
||||
send <B>ab</B> <B>84</B> untranslated,
|
||||
which becomes <B>ab</B> <B>54</B> translated.

(The netbsd source has a misunderstanding here, and seems to associate

the <B>54</B> and <B>84</B> to the ThinkPad model - cf. the defines

KEYB_R_MF2ID2TP75X, KEYB_R_MF2ID2TP76X.)

<P>Several 122-key keyboards are reported to send <B>ab</B> <B>86</B>.

Here translated and untranslated values coincide.

(Reports mention "122-Key Enhanced Keyboard", "standard 122-key keyboard",

"122 Key Mainframe Interactive (MFI) Keyboard".)
|

<P>David Monro reports <B>ab</B> <B>85</B> for a
|

<A HREF="scancodes-6.html#NCD97">NCD N-97</A> keyboard.
|
||||
Tim Clarke reports <B>ab</B> <B>85</B> for the
|
||||
"122-Key Host Connect(ed) Keyboard".
|

<P>He also reports
|
||||
<I>Also, when playing with my KVM problems Belkin gave me a
|
||||
105-key Windows keyboard which Id.s itself as 18ABh</I>.
|
||||
<P>Linux 2.5.25 kernel source has 0xaca1 for a
|
||||
"NCD Sun layout keyboard". It also mentions 0xab02 and 0xab7f,
|
||||
but these arise as (mistaken) back translations from
|
||||
<B>ab</B> <B>41</B> and <B>ab</B> <B>54</B>.
|
||||
<P>Ralph Brown's Interrupt list mentions "old Japanese 'G', 'P', 'A' keyboards",
|
||||
with keyboard IDs <B>ab</B> <B>90</B>, <B>ab</B> <B>91</B>,
|
||||
<B>ab</B> <B>92</B>. Here translated and untranslated versions
|

coincide. ID <B>ab</B> <B>90</B> was also mentioned

<P>
|
||||
<H2><A NAME="ss9.4">9.4 Correspondence</A>
|
||||
</H2>
|
||||
|
||||
<P>For the traditional keys the correspondence is fairly clear:
|
||||
above we saw the
|
||||
<A HREF="#translationtable">translation table</A>,
|
||||
and Set 1 equals translated Set 2, and Set 3 equals Set 2 in most cases
|
||||
where Set 2 has a single (non-escaped) scancode,
|
||||
and in any case the correspondence is constant (and given
|
||||
<A HREF="#correspondence">below</A>).
|
||||
<P>On the other hand, modern keyboards have all kinds of multimedia
|
||||
and other additional keys, and what happens for them is completely
|
||||
random, and varies from keyboard to keyboard.
|
||||
<P>Let us look at an example.
|
||||
<P>The
|
||||
<A HREF="scancodes-5.html#msinternet">Microsoft Internet keyboard</A>
|
||||
has keys Search, Favorites, Stop, Forward, Back, My Computer,
|
||||
Mail, Web / Home, Calculator with translated Set 3 scancodes
|
||||
<B>65</B>, <B>66</B>, <B>68</B>, <B>69</B>, <B>6a</B>,
|
||||
<B>6b</B>, <B>6c</B>, <B>97</B>, <B>99</B>, respectively,
|
||||
and translated Set 2 scancodes <B>e0</B> <I>xx</I>, with
|
||||
<I>xx</I> = <B>65</B>, <B>66</B>, <B>68</B>, <B>69</B>,
|
||||
<B>6a</B>, <B>6b</B>, <B>6c</B>, <B>32</B>, <B>21</B>.
|
||||
<P>On the other hand, the
|
||||
<A HREF="scancodes-5.html#ibmrapidaccessii">IBM Rapid Access II keyboard</A>
|
||||
has keys CD stop, CD play, Volume D, Volume U, CD back, CD fwd
|
||||
with translated Set 3 scancodes
|
||||
<B>69</B>, <B>6a</B>, <B>6b</B>, <B>6c</B>, <B>6d</B>, <B>44</B>,
|
||||
and translated Set 2 scancodes <B>e0</B> <I>xx</I>, with
|
||||
<I>xx</I> = <B>20</B>, <B>22</B>, <B>21</B>, <B>23</B>,
|
||||
<B>24</B>, <B>12</B>.
|
||||
<P>Thus, different keyboards have different mappings between Set 2
|
||||
and Set 3 codes.
|
||||
<P>
|
||||
<H2><A NAME="ss9.5">9.5 Use</A>
|
||||
</H2>
|
||||
|
||||
<P>Can these other scancode sets be used? Probably not.
|
||||
<P>() Translated scancode Set 1 has weird codes that nobody wants to use.
|
||||
<P>(i) My MyCom laptop does not support scancode sets 1 and 3 at all.
|
||||
<P>(ii) Some laptops have special key combinations that bring one
|
||||
into a setup or configuration utility. It is impossible to do
|
||||
anything useful, or to get out of it again, when the scancode mode
|
||||
is not translated Set 2.
|
||||
<P>(iii) Many keyboards have bugs in scancode sets 1 and/or 3 but
|
||||
are fine in scancode Set 2.
|
||||
Vojtech Pavlik reports that his BTC keyboard has the same codes
|
||||
for the '1' and '2' keys in Set3, both having the code for '1').
|
||||
On my BTC keyboard the key up value for Esc and 1 are both <B>ff</B>
|
||||
in scancode Set 1. My Safeway keyboard has untranslated Set 1 equal
|
||||
to translated Set 2, except for the multimedia keys, where
|
||||
untranslated Set 1 equals untranslated Set 2.
|
||||
<P>(iv) A big advantage of Set 3 is that each key generates a unique code
|
||||
so that one does not need to parse sequences. However, the BTC keyboard
|
||||
mentioned
|
||||
<A HREF="scancodes-5.html#BTC">above</A> generates <B>e0</B> <B>6f</B>
|
||||
for its Macro key also in scancode mode 3. The Safeway keyboard mentioned
|
||||
<A HREF="scancodes-5.html#safeway23">above</A> does not generate any codes
|
||||
for its multimedia keys in scancode mode 3.
|
||||
<P>(v) Some keyboard controllers cannot handle Set 3 values that are
|
||||
larger than 0x7f, and give
|
||||
<A HREF="#contagious">peculiar results</A>
|
||||
for e.g. the Windows keys in translated scancode mode 3.
|
||||
The result is that the following key is "eaten": the key down action
|
||||
turns into a key up.
|
||||
<P>(vi) The USB legacy support only supports translated Set 2.
|
||||
<P>(vii) The
|
||||
<A HREF="http://www.microsoft.com/hwdev/download/desinit/scancode.zip">Microsoft Keyboard Scan Code Specification</A> writes:
|
||||
<I>In the very early days of Windows NT, an attempt was made
|
||||
to use the much more orthogonal Scan Code Set 3, but due to bugs
|
||||
in the implementation of this Scan Code Set on numerous OEM
|
||||
keyboards, the idea was abandoned.</I>
|
||||
And also: <I>Scan Code Set 3 is not used or required for operation
|
||||
of Microsoft operating systems.</I>
|
||||
<P>(viii) Others also tried Set 3. The PS/2 version of the HP9000
|
||||
workstation uses it. This is fine with HP's keyboards but causes
|
||||
some problems with foreign keyboards.
|
||||
<P>(ix) It is said that Hal Snyder of Mark Williams, Co remarked:
|
||||
"We find that about 10% of cheap no-name keyboards do not work
|
||||
in scan code set 3".
|
||||
<P>(x) These days Linux probes the keyboard, and may try to enable Set 3.
|
||||
This is good for learning a lot about strange keyboards.
|
||||
It is bad for having a stable system that just works.
