<p>SUBJECT: Locator Input Model for ANSI Terminals (sixth revision) |
||||||
|
<p>This memo defines support for locator input devices on ANSI text |
||||||
|
and graphics terminals. The goal is to make terminals able to |
||||||
|
support the same class of applications popular on PCs and Workstations. |
||||||
|
This is not meant to imply terminals must be compatible with |
||||||
|
workstations, some limitations are unavoidable. The intent is |
||||||
|
to provide a minimal set of locator functions which make sense |
||||||
|
for terminals. Comments are welcome. |
||||||
|
<p><b><a name="Overview">Overview</a></b> |
||||||
|
<p>The terminal is supplied with a locator port which can be used |
||||||
|
to connect an optional <i>mouse</i> or tablet. When locator reporting |
||||||
|
is enabled, a seperate input cursor appears, and the terminal |
||||||
|
tracks the locator locally with no host intervention. Individual |
||||||
|
locator events such as locator button transitions or movement |
||||||
|
may be programmed to send locator reports to the host. |
||||||
|
<p>Each locator report includes the specific event which initiated |
||||||
|
the report, the current state of the locator keys, and the coordinates |
||||||
|
of the input cursor at the time of the event. |
||||||
|
<p>The locator is treated as a manual input device similar to a keyboard. |
||||||
|
Locater events are queued in the keyboard input silo along with |
||||||
|
keystrokes. |
||||||

||||||
|
<p>Locator reporting can be selectively enabled from the host using |
||||||
|
a DEC private control sequence. When disabled (the power up default), |
||||||
|
the locator cursor does not appear, and the locator buttons are |
||||||
|
inactive. When enabled, the locator cursor is visible, and the |
||||||
|
terminal tracks the locator locally with no host intervention. |
||||||
|
Individual locator events such as locator button transitions |
||||||
|
or movement may be programmed to send locator reports to the host. |

<p>Ps may assume the following values |
||||||
|
<p> 0 locator disabled (default) |
||||||
|
<p> 1 locator reports enabled |
||||||
|
<p> 2 one shot (allow one report, then disable) |

<p> 2 character cells |

|
<p>One shot mode is provided for applications that desire simple |
||||||
|
graphics input similar to Tektronix GIN mode (no unsolicited reports). |
||||||
|
If parameter value 2 is selected, the next trigger event that |
||||||
|
occurs will generate a single locator report. No further locator |
||||||
|
reports will occur (the locator will be disabled), until another |
||||||
|
DECELR sequence is received. |
||||||
|
<p>The coordinate units for locator position reports may be selected |
||||||
|
to either of two coordinate systems used by terminal software |
||||||
|
at the lowest level. Physical pixels is the "least common |
||||||
|
denominator", and is useful for computing sixel positions. |

|
<p><i><a name="Locator_Position_Reporting">Locator Position Reporting</a></i> |
||||||
|
<p>When a selected trigger event occurs such as a button press or |
||||||
|
release, the terminal transmits a locator position report as follows. |
||||||
|
<p> DECLRP - DEC Locator Report |
||||||
|
<p> CSI Pe ; Pb ; Pr ; Pc ; Pp & w |
||||||
|
<p> 2/6 7/7 |
||||||
|
<p> Pe is the event code |
||||||
|
<p> Pb is the button code |
||||||
|
<p> Pr is the row coordinate |
||||||
|
<p> Pc is the column coordinate |
||||||
|
<p> Pp is the third coordinate (page number) |
||||||
|
<p>Pe, the event code indicates what event caused this |
||||||
|
report to be generated. The following event codes are defined: |
||||||
|
<p> 0 - request, the terminal received an explicit request |
||||||
|
<p> for a locator report, but the locator is unavailable |
||||||
|
<p> 1 - request, the terminal received an explicit |
||||||
|
<p> request for a locator report |
||||||
|
<p> 2 - left button down |
||||||
|
<p> 3 - left button up |
||||||
|
<p> 4 - middle button down |
||||||
|
<p> 5 - middle button up |
||||||
|
<p> 6 - right button down |
||||||
|
<p> 7 - right button up |
||||||
|
<p> 8 - fourth button down |
||||||
|
<p> 9 - fourth button up |
||||||
|
<p> 10 - locator outside filter rectangle |
||||||
|
<p>Pb is the button code, ASCII decimal 0-15 indicating which buttons |
||||||
|
are down if any. The state of the four buttons on the locator |
||||||
|
correspond to the low four bits of the decimal value, "1" |
||||||
|
means button depressed |
||||||
|
<p> 0 - no buttons down |
||||||
|
<p> 1 - right |
||||||
|
<p> 2 - middle |
||||||
|
<p> 4 - left |
||||||
|
<p> 8 - fourth |
||||||
|
<p>Pr is the row coordinate of the locator position in the page, |
||||||
|
encoded as an ASCII decimal value. If Pr is omitted, the locator |
||||||
|
position is undefined (outside the terminal window for example). |
||||||
|
<p>Pc is the column coordinate of the locator position in the page, |
||||||
|
encoded as an ASCII decimal value. If Pc is omitted, the locator |
||||||
|
position is undefined (outside the terminal window for example). |
||||||
|
<p>Pp is the page coordinate of the locator position encoded as an |
||||||
|
ASCII decimal value. The page coordinate may be omitted if the |
||||||
|
locator is on page one (the default). |
||||||
|
<p>Each locator report includes both the specific transition which |
||||||
|
caused this event, and the current button state. This allows |
||||||
|
software to determine what event just occured and which buttons |
||||||
|
are down without keeping track of previous events or button state. |
||||||
|
In a multiprocess shared locator environment, an application |
||||||
|
may not know the previous button state. This dual reporting also |
||||||
|
allows applications to recover from lost locator reports. |
||||||
|
<p>Each locator event generates a single report. In the rare situation |
||||||
|
where two events occur simultaneously (within a single sampling |
||||||
|
period), the terminal will report this as two separate events. |
||||||
|
The order of reporting shall be by increasing event code number |
||||||
|
(left button first). |
||||||
|
<p>Locator events are queued in the keyboard input silo just like |
||||||
|
keystrokes. Each locator event occupies one position in the silo |
||||||
|
(the keyboard silo currently must have at least 9 positions). |
||||||
|
If the input silo becomes full, the locator and keyboard are |
||||||
|
locked until there is again room in the silo. The sequential |
||||||
|
order of keystroke and locator events is strictly maintained. |
||||||
|
<p>It is the responsibility of the host to accept data fast enough |
||||||
|
to avoid locking the locator unintentionally. The limited buffering |
||||||
|
inside the terminal gives the host a little more time to process |
||||||
|
locator events smoothly. |
||||||
|
<p>When the keyboard is locked, the "wait" indicator on |
||||||
|
the keyboard turns on. The keyboard is automatically locked any |
||||||
|
time the keyboard input silo is full. The keyboard can be locked |
||||||
|
explicitly using the keyboard action mode (KAM) control function. |
||||||
|
<p>When the locator is locked, the terminal continues to track the |
||||||
|
locator, but the input cursor changes shape to appear as a wristwatch |
||||||
|
(or other shape indicating to wait). The wristwatch cursor indicates |
||||||
|
that locator button transitions will be ignored, but allows the |
||||||
|
user to continue positioning in anticipation of the locator being |
||||||
|
unlocked. The locator is automatically locked any time the input |
||||||
|
silo is full. |
||||||
|
<p>Locator-ahead, analogous to keyboard type-ahead is supported by |
||||||
|
having each report include the locator position at the time of |
||||||
|
the event, and maintaining the sequential order of keystroke and |
||||||
|
locator events. |
||||||
|
<p>A final implication of using the keyboard silo to buffer text |
||||||
|
locator events is that locator and keyboard input should be associated |
||||||
|
with the same session at all times. The session to receive these |
||||||
|
events is sometimes called the "active session" or "input |
||||||
|
focus". In a multi-session windowing environment, the input |
||||||
|
cursor is allowed to roam freely over the entire screen in response |
||||||
|
to locator movement. The input cursor is never occluded when |
||||||
|
locator reporting is enabled in one or more sessions. Each session |
||||||
|
enables locator reporting independently. The following cases |
||||||
|
describe the locator interaction with session viewports and scroll |
||||||
|
regions. |
||||||
|
<p>1. The input cursor is within the active session's viewport. |
||||||
|
Pressing a button on the locator sends a locator report when enabled. |
||||||
|
<p>2. The input cursor is inside the active session's viewport, |
||||||
|
but outside the range of defined coordinates for that session. |
||||||
|
Pressing a button on the locator will generate a report with omitted |
||||||
|
coordinates (position undefined). An example would be when the |
||||||
|
input cursor is outside the active scrolling region, and the origin |
||||||
|
mode has been set to relative. To use the locator to adjust scroll |
||||||
|
margins, the origin mode must be absolute. |
||||||
|
<p>3. The input cursor is not contained in any viewport. Pressing |
||||||
|
a button on the locator will have no effect. To support "pop |
||||||
|
up" menus anywhere on the screen, the entire screen must |
||||||
|
be a viewport for at least one session. |
||||||
|
<p>4. The input cursor is within a viewport of a session which is |
||||||
|
not the active session. Pressing a button on the locator will |
||||||
|
normally make the session containing the input cursor the active |
||||||
|
session (possibly changing the occlusion order of viewports, and |
||||||
|
the shape of the locator). This case is the responsibility of |
||||||
|
the "window manager" which is free to define its own |
||||||
|
user interface. Two recommendations are: (1) No locator report |
||||||
|
should be sent to the previous active session, since the locator |
||||||
|
is not in its viewport; and (2) If locator reporting is enabled |
||||||
|
in the new session, a locator report should not be transmitted |
||||||
|
to avoid application side affects when selecting another window. |
||||||
|
<p>Requesting A Locator Position Report |
||||||
|
<p>The host may explicitly request a locator position report any |
||||||
|
time locator reporting is enabled (DECELR). Upon receiving such |
||||||
|
a request, the terminal will immediately send a single locator |
||||||
|
report (DECLRP) with event code 1 indicating the current locator |
||||||
|
position. |
||||||
|
<p>If the session receiving the request is the active session, but |
||||||
|
the locator is not within the defined coordinate range for that |
||||||
|
session, the terminal will respond with omitted coordinates (locator |
||||||
|
position undefined). |
||||||
|
<p>If the session receiving the request is not currently active (the |
||||||
|
locator is being used in another session), the report will specify |
||||||
|
event code 0 (locator unavailable). Locator state from the active |
||||||
|
session should not be made available to inactive sessions. |
||||||
|
<p>If the locator is disabled (DECELR), the terminal should still |
||||||
|
respond with event code 0 (to avoid timing out the application). |

|
<p> Pl - Left boundary of filter rectangle |
||||||
|
<p> Pb - Bottom boundary of filter rectangle |
||||||
|
<p> Pr - Right boundary of filter rectangle |
||||||
|
<p>The DECEFR control sequence defines the coordinates of a filter |
||||||
|
rectangle, and activates it. Anytime the locator is detected |
||||||
|
to be outside a filter rectangle, an outside rectangle event is |
||||||
|
generated and the rectangle is disabled. Filter rectangles are |
||||||
|
always treated as "one-shot" events. Defining a new |
||||||
|
rectangle re-activates it. |
||||||
|
<p>Applications can re-define the rectangle at any time even if its |
||||||
|
already active. If a rectangle which does not contain the locator |
||||||
|
is specified, the terminal will generate an outside rectangle |
||||||
|
report immediately and deactivate it. |
||||||
|
<p>Pt, Pl, Pb, and Pr are in coordinates units specified by the last |
||||||
|
DECELR sequence. The filter rectangle includes the boundaries |
||||||
|
(similar to other rectangular area operations). The origin is |
||||||
|
coordinate pair 1:1 in the upper left corner. If any parameters |
||||||
|
are omitted, they are defaulted to the current locator position. |
||||||
|
Sending DECEFR with no parameters will cause the application to |
||||||
|
be notified for any locator movement ("unfiltered movement |
||||||
|
event"). |
||||||
|
<p>DECELR always cancels any previous filter rectangle definition. |
||||||
|
This gaurantees that when an application enables locator reports, |
||||||
|
there will never be an outstanding filter rectangle. |
||||||
|
<p>If a filter rectangle lies on the edge of the defined coordinate |
||||||
|
space for the active session, and the locator crosses that edge, |
||||||
|
the rectangle may be triggered to send a report with omitted coordinates |
||||||
|
(locator position undefined). |
||||||
|
<p>If the active session receives a filter rectangle with explicit |
||||||
|
coordinates while the locator is outside the defined coordinate |
||||||
|
space, the rectangle will be triggered to send a report with omitted |
||||||
|
coordinates. |
||||||
|
<p>If the active session receives a filter rectangle with omitted |
||||||
|
coordinates (that is, use the current position) while the locator |
||||||
|
is outside the defined coordinate space (position undefined), |
||||||
|
the rectangle will be triggered the next time the locator is within |
||||||
|
the defined coordinate space. |
||||||
|
<p>If a session which is not the active session receives a filter |
||||||
|
rectangle with explicit coordinates, it should trigger immediately |
||||||
|
with position undefined. If a session which is not the active |
||||||
|
session receives a rectangle with omitted coordinates, it should |
||||||
|
trigger the next time the locator is within the defined coordinate |
||||||
|
space for that session, which cannot happen until the session |
||||||
|
becomes active. |

|
<p>The locator can be used in REGIS, and in Tektronix GIN mode during |
||||||
|
Tektronix 401x emulation. |
||||||
|
<p>REGIS One-shot Graphics Input Mode is provided for backward compatibility |
||||||
|
with the VT240. When an application requests graphics input, |
||||||
|
a cross hair cursor appears which may be positioned using either |
||||||
|
the arrow keys (as on the VT240), or a locator device. Pressing |
||||||
|
any non-arrow key on the keyboard which is not dead or a button |
||||||
|
on the locator will cause the following actions: |
||||||
|
<p>1. The ASCII code or codes for the non-arrow key that was pressed |
||||||
|
is sent to the host. Each locator button can be programmed to |
||||||
|
send a sequence of 0 to 6 characters. This allows the locator |
||||||
|
to be programmed to work with existing applications (see DECLKD |
||||||
|
below). |
||||||
|
<p>2. The coordinates of the input cursor at the time that the non-arrow |
||||||
|
key was depressed are sent to the host, expressed as an absolute |
||||||
|
bracketed extent in user coordinates. |
||||||
|
<p>3. The graphics input cursor disappears from the screen and the |
||||||
|
terminal exits graphics input mode. |
||||||
|
<p>While the terminal is in graphics input mode, no further data |
||||||
|
from the application is processed until the locator input is complete |
||||||
|
and a report is generated. |
||||||
|
<p>The mouse and arrow keys may be intermixed freely in REGIS One-Shot |
||||||
|
Graphics Input Mode. Since the tablet is an absolute positioning |
||||||
|
device, use of the arrow keys in combination with the tablet would |
||||||
|
cause inconsistent and confusing behavior. The arrow keys are |
||||||
|
disabled for input cursor positioning when the tablet is in proximity |
||||||
|
because the tablet establishes a unique screen position. |

|
<p>The DECLKD device control string down line loads one or more definitions |

|
for use by the Locator device during REGIS One-shot Graphics Input. |
||||||
|
These definitions are called Locator Key Definitions (LKDs). |
||||||
|
<p>DECLKD is intended for older applications that use ReGIS one-shot |
||||||
|
input mode with keystroke commands like "A", "B", |
||||||
|
"C", etc. These commands can be re-bound to buttons |
||||||
|
on the mouse by sending DECLKD (possibly before running the application). |
||||||
|
<p>There are six bytes available to each of the locator keys (upto |
||||||
|
four). A power-up restart or RIS will cause the LKDs to be set |

to their default value. LKDs are not affected by DECSTR. |

|
Stnd / Stnu - Key selection code n, slash delimeter, and string |
||||||
|
parameter n for down and up key transitions. |
||||||
|
<p>Kyn is a single ASCII digit, and Std/Stu is a series of ASCII |
||||||
|
hex pairs. If Std or Stu is omitted, the corresponding button |
||||||
|
string will be empty. Key definition strings are delimited with |
||||||
|
a semicolon (";"). |
||||||
|
<p>Graphics and ANSI Locator Input |
||||||
|
<p>Support for graphics input in REGIS is extended by allowing ANSI |
||||||
|
locator input to operate normally regardless of whether the host |
||||||
|
output stream is being interpreted as ANSI or REGIS. If ANSI |
||||||
|
locator reporting is enabled, keystrokes and locator position |
||||||
|
reports may be generated without being solicited from the host. |
||||||
|
Characters received from the host are executed instead of buffered, |
||||||
|
so graphics output and graphics input may occur simultaneously. |
||||||
|
<p>If one-shot graphics input mode is entered (REGIS report position |
||||||
|
interactive) while ANSI locator reporting is enabled, the locator |
||||||
|
cursor will change to a cross-hair. Pressing a non-arrow key |
||||||
|
on the keyboard will send the character for that key followed |
||||||
|
by the REGIS user coordinates as a bracketed extent. If a locator |
||||||
|
button had been pressed instead, the characters for the locator |
||||||
|
button (if any) would be sent followed by the REGIS position report, |
||||||
|
and finally the ANSI locator report (DECLRP) if enabled. Upon |
||||||
|
sending the REGIS position report, the terminal exits one-shot |
||||||
|
input mode, and the input cursor returns to its previous state. |
||||||
|
<p>The ANSI locator report should still be sent in the above situation |
||||||
|
(if enabled) to keep the two modes independent. This allows filter |
||||||
|
rectangles to continue operating, and also keeps the ANSI state |
||||||
|
(last DECLRP seen) consistent with the last button transition. |
||||||
|
<p>The order of reports is chosen to allow a subroutine to send |
||||||
|
R(P(I)) and read the REGIS response that follows without regard |
||||||
|
to whether ANSI locator reports are enabled. |
||||||
|
<p>Since the ANSI locator report is in the form of a control sequence, |
||||||
|
it should not inferfere with REGIS reports. No special procedure |
||||||
|
is used to indicate REGIS data from the terminal. This is backward |
||||||
|
compatible with the VT240 since ANSI locator reports can only |
||||||
|
occur if ANSI locator reporting is enabled. |
||||||
|
<p>The suspension of graphics output during REGIS one-shot graphics |
||||||
|
input remains the same. This is necessary to support rubber-band |
||||||
|
cursors. Rubber-band cursors use the REGIS output position as |
||||||
|
one reference point, and the locator input position as the other. |
||||||
|
Rubber-band cursors are specified as an option on the REGIS report |
||||||
|
position interactive command. |
||||||
|
<p><b><a name="LOCATOR_DEVICE_SUPPORT">LOCATOR DEVICE SUPPORT</a></b> |
||||||
|
<p>Locator support is currently planned as an extension to the level |
||||||
|
3 character cell architecture. The primary device attributes |
||||||
|
response will report the locator extension as parameter value |
||||||
|
15 (locator port), and 29 (text locator). |
||||||
|
<p>Host software may request a Device Status Report (DSR) to determine |
||||||
|
whether a locator is available. Upon receiving the appropriate |
||||||
|
DSR request, the terminal will respond to indicate the locator |
||||||
|
is ready if a locator device is plugged in, and has transmitted |
||||||
|
a successful self test message. |
||||||
|
<p><i><a name="Locator_Device_Status_Report_DSR_">Locator Device |
||||||
|
Status Report (DSR)</a></i> |
||||||
|
<p>Host request locator device status CSI ? 55 n |
||||||
|
<p>No locator CSI ? 53 n |
||||||
|
<p>Locator ready CSI ? 50 n |
||||||
|
<p>Locator busy CSI ? 58 n |
||||||
|
<p>The locator busy response can occur when an alternate session |
||||||
|
has selected locator controller mode (see below). |
||||||
|
<p><i><a name="Locator_Controller_Mode"></a>Locator Controller Mode</i> |
||||||
|
<p>Locator Controller Mode allows the host to communicate directly |
||||||
|
with the locator device without terminal intervention (similar |
||||||
|
to printer controller mode). When locator controller mode is |
||||||
|
set, all data received at the host port is transferred directly |
||||||
|
to the locator port without interpretation by the display terminal. |
||||||
|
<p>The only exceptions are the communications control characters |
||||||
|
XON/XOFF (if enabled), and the control sequence to disabled locator |
||||||
|
controller mode. All characters received at locator port are |
||||||
|
transferred to the host port without interpretation. The host |
||||||
|
assumes full responsibility for the locator device. |
||||||
|
<p>Locator controller mode is desirable for two reasons: |
||||||
|
<p>1. It allows the host to explicitly initialize or configure locator |
||||||
|
devices. A foriegn locator device might not wake up in DEC format |
||||||
|
for example. |
||||||
|
<p>2. It allows the locator port to be used for other auxilliary |
||||||
|
input devices. A bar code reader could be interfaced to the locator |
||||||
|
port for example, allowing the terminal to support a bar code |
||||||
|
reader without pre-empting the printer port. |
||||||
|
<p>Turn off locator controller mode (MC) CSI 6 i |
||||||

<p>Turn on locator controller mode (MC) CSI 7 i |

<h1 align="center">VT100 escape codes</h1> |
||||||
|
|
||||||
|
<p>This document describes how to control a VT100 terminal. The |
||||||
|
entries are of the form "name, description, escape code".</p> |
||||||
|
|
||||||
|
<p>The name isn't important, and the description is just to |
||||||
|
help you find what you're looking for. What you have to do is |
||||||
|
send the "escape code" to the screen. These codes are often |
||||||
|
several characters long, but they all begin with <tt>^[</tt>. |
||||||
|
This isn't the two characters <tt>^</tt> and <tt>[</tt>, but |
||||||
|
rather a representation of the ASCII code ESC (which is why |
||||||
|
these are called escape codes).</p> |
||||||
|
|
||||||
|
<p>ESC has the decimal value 27 and should be sent before the rest of the code, which is simply an ASCII string.</p> |
||||||
|
|
||||||
|
<p>As an example of how to use this information, here's how |
||||||
|
to clear the screen in C, using the VT100 escape codes:</p> |
||||||
|
|
||||||
|
<pre> #define ASCII_ESC 27 |
||||||
|
printf( "%c[2J", ASCII_ESC ); |
||||||
|
|
||||||
|
<i>or</i> |
||||||
|
|
||||||
|
puts( "\033[2J" ); |

<h1>VT100 emulation resources collection</h1> |
||||||
|
|
||||||
|
<p>This page lists some files and sites I found helpful when developing <a href="https://github.com/MightyPork/ESPTerm">ESPTerm</a>.</p> |
||||||
|
|
||||||
|
<h2>Web references</h2> |
||||||
|
|
||||||
|
<ul> |
||||||
|
<li>An invaluable resource in my research was the website <a href="http://vt100.net/">vt100.net</a> which provides |
||||||
|
original manuals for manu VT models.</li> |
||||||
|
|
||||||
|
<li>The <a href="http://invisible-island.net/xterm/ctlseqs/ctlseqs.html">Xterm manual page</a> also proved immensely useful. |
||||||
|
I have even made a <a href="espterm-xterm.html">copy of it</a> with highlighted differences and missing features |
||||||
|
in ESPTerm.</li> |
||||||
|
|
||||||
|
<li>Some sequences can also be found in the <a href="https://www.gnu.org/software/screen/manual/html_node/Control-Sequences.html">GNU Screen manual page</a></li> |
||||||
|
|
||||||
|
<li>Application keys mode became clear after reading this page: |
||||||
|
<a href="http://www.tldp.org/HOWTO/Keyboard-and-Console-HOWTO-21.html">www.tldp.org/HOWTO/Keyboard-and-Console-HOWTO-21.html</a>.</li> |
||||||
|
|
||||||
|
<li>When trying to understand what codes should be sent by function and control |
||||||
|
keys, this page provided some great insight: |
||||||
|
<a href="http://invisible-island.net/xterm/xterm-function-keys.html">invisible-island.net/xterm/xterm-function-keys.html</a></li> |
||||||
|
</ul> |
||||||
|

|
<h2>Collected files and memos</h2> |
||||||
|
|
||||||
|
<p>Those are some documents I've found on the internet while researching for ESPTerm |
||||||
|
and preserve them here for reference should the original sources disappear.</p> |

ObBusinessHack: Customer wants a CD-ROM multimedia encyclopaedia, so I buy a |
||||||
|
Soundblaster Pro for #75 which comes bundled with a multimedia encyclopaedia |
||||||
|
CD-ROM. After carefully removing the "not to be sold separately" notice from |
||||||
|
the CD, I sell it on for #75. Result: One free Soundblaster Pro and a happy |
||||||
|
(but gullible) customer. (Allegedly ;) |
