Preface

+ +This document accompanies the Konsole program, which is a terminal emulation +for the X Windows System. Since material about the extend and precise semantics +of the emulatation intended to be handled by this programs is hard to find on the +internet today, it came out nessesary to include a more precise specification within +their release. +Hopefully, this helps to clearify the relation to the VT100, VT102, Linux, XTerm +and ansi.sys (ANSI-BBS) terminals, which are the target of these programs. Further, +it specifies which codes are interpreted by them, and what has been omitted. +

+To begin with, all of the above call themselfes "ANSI" emulations, which makes this +notion pretty vage. "ANSI" referes here to the American National Standards +Institute's documents X3.41-1974 and X3.64-1977. DEC partially implemented this +standart in their VT100 terminal, with some additions. The VT102 is a later extension +of that. Both the Linux console and the XTerm emulation implement most of VT102, +with some additions. MS stepped in later and produced another ANSI emulation, +ansi.sys, for their OS, which became of some relevance in BBS style +telecommunication programs. One can view this as a small subset of the VT100 +emulation, with some additions, of cause. +This situation is further confused by the fact, that often many versions of the +above terminals and emulations are out, one able to do a little more or less then +the other. +

+I'm working towards a +close integration of the konsole's source code with this document, but it +is still a long way to go. +

+Currently, the body of this document is mainly a concept data base, that +referes to the VT100 component of the emulation. Though the codes accepted by +konsole are now clearly indicated, a comparison to the xterm and Linux console +emulation is missing. +

+The konsole emulation sources is not linked closely with it's documentation, +and, also accurate at the time of writing, it can still fall slightly appart, +though the codes accepted and produced by konsole should be properly listed. +Work is currently in progress to fix this issue. + + + +

Introduction

+ In a traditional UNIX installation a single machine (host) served + several users by means of terminals attached to this host by a serial + cable. These terminals (end points) where specialized devices, either + regular ttys (printer with keyboard) or later more sophisticated + things with cathode ray tubes. +

+ Today, hardware has become so cheap, that each single user could + be provided with a complete host/display combination for the former + price of a terminal. +

+ Additional, and here we come to the X in the emulation, display + devices have become graphical while the original terminal where + only able to show characters but not graphics. +

+ To allow programs designed for the original configuration to be + used in the contemporary setup, "terminal emulations" where invented. + In these emulations, the whole original setup is simulated. +

+ The serial cable is folded into the operating system as a sort of + loop back device, and a program, the terminal emulation, uses modern + means of graphical user interfaces to behave like an earlier terminal. + To complete the picture, the host in the diagram is replaced by the + application that runs in the emulation (typically a shell or an old + editor). So, terminal emulations are in fact interfaces to character + oriented applications. +

+ This document describes the implementations of a program named + "konsole", which is such an X terminal emulation. Since konsole + is distributed under the GPL, meaning that it's source code is + available to whoever likes to hack on it, the program would be + incomplete without a proper introduction into the code and it's + concepts. Thus, this text is to complement the program and the + source with the remaining informations to make a complete product. +

A first refinement

+ Before we can come to the actual implementation, quite some + notions have to be introduced. We have to get us an idea what + a terminal emulation does in more detail. +

+ To this end, a simple model of the terminal and it's operation + is given, which is later extended and refined as we come deeper + into matter and implementation. +

+ At some level conception, a terminal can be described as a + (abstract) data model. This means it has some type of state + together with operations on that data type. These operations + are somehow encoded to be passed over the serial line. +

+ The concrete model is often loosely named the "emulation", + the specific encoding chosen, the "protocol". +

+ There are two principle models in use. The first, stream like + one, which is related to a tty, consideres the terminal as an + indefinit long and wide sheet of paper on which a printer head + types the characters that come in over the line. Typical examples + are shell scripts, make and other programs producing sequential + protocols of their activity. Their basic data type is a list of + list of characters. +

+ The second principle model is used by applications written + especially for crt devices, so called full screen applications. + These treat the terminal as a matrix of characters where each + position can be individually addressed and written to. Typical + representatives are full screen editors like vi and emacs, + file managers like mc and mail readers like mutt. +

+ Though the second model is newer, it's age does not imply a + preference. To the contrary, both models have a right for their + own and are both to be supported. The first model is fully + expressed within konsole in form of it's ref:history buffer. +

+ Note, that although the second model definitely build on the + first one in almost any respect, it cannot fully express it, + since it introduces a finite line length, while the first + model works with indefinite lines. +

+ Since application with both view of things are typically run + within the same session, some effort has been made within + konsole to maintain both ideas simultaniously, but only with + limited success so far. +

+ In both models, the notion of a current position (historically + a printer's head, nowadays visualized by a cursor) is present. + "Printing" a character at the current position and advancing + the head together with the starting a new line are the most + fundamental operations of the emulation. +

+ The full screen model basically adds the possibility to position + the cursor and to overwrite and clear the screen. +

+ A plethora of additional (more or less useful) commands are + then added on this by every specific emulation, see below for + the awful details. +

+ +

Parts of the model

+ All the following in this section is an outline. +

+ Parts of the terminal description +

State +
This is mainly the screen, the cursor (including it's graphical state) + and some hidden mode variables. Note that the state cannot be investigated + by the attached host. +
Interface +
That's what goes over the wire. Beside being related to objects, this + appears so closely related to contemporal process communication, that + it might be discussed in likely terms. +
We have information flowing in both directions. On could destinguist + between: +
Commands +
These are "calls" of the terminals interface by the host which cause + some change of the terminals state, but do not end in a response. +
Requests +
These are "calls" of the terminals interface by the host which do not cause + any change of the terminals state, but end in a response of the terminal. + Clearly, requests are somehow used to investigate the state of the terminal. +
Events +
These are signals from the terminal caused by the user affecting the + mouse or keyboard to the host. +
Replys +
These are send by the terminal as a result of a Request from the hosts. +
Encoding/Decoding +

+ + + + +
Control Sequences
+

+ Conceptually, the commands to the terminal emulation are encoded if form + of byte sequences to meet the restrictions of the transport media. These + sequences have pretty different originations and therefore the format of + the sequences are inhomogenous. +

+ Refering both to their origin and form, one can group the overall encoding + schemes as follows: +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + +
+
Name Pattern Scope Comment
Printable Ascii Characters 32..126 ASCII ECMA This is the most original pattern of all. The characters to be + displayed are passed over the chanel and are interpreted by the + terminal (emulation) as instructions to display the corresponding + glyph of the ascii character set. Contempory emulations include the + upper half (128..255) of the extentions to the national ascii character + sets, also.
Ascii Control Characters 0..26,28..31,127 ASCII ECMA Ascii defines some non-printable, but format effecting characters, too. + Depending on the emulation, at least some of them are given a meaning. + The typically implemented ones are those that are handled by a teletype + like device.
Simple Escape Sequence ESC C ECMA These sequences are made up from an ESC character followed by + exactly one other character in the range ???..???.
CSI Sequence ESC [ Parameters {I} C ECMA

More on Control Sequences

Control Characters

+ Control characters (codes 0x00 - 0x1f inclusive) are specifically excluded + from the control sequence syntax, but may be embedded within a control + sequence. Embedded control characters are executed as soon as they are + encountered by a VT100. The processing of the control sequence then + continues with the next character received. The exceptions are: + if the ESC character occurs, the current control sequence + is aborted, and a new one commences beginning with the ESC + just received. If the character CAN (0x0c) or the + character SUB (0x0e) occurs, + the current control sequence is aborted. The ability to embed control + characters allows the synchronization characters XON and XOFF to be + interpreted properly without affecting the control sequence. +

CSI Sequences

Control Sequence Introducer (CSI): +: An escape sequence that provides + supplementary controls and is itself a prefix affecting the + interpretation of a limited number of contiguous characters. + In the VT100, the CSI is: <ESC>[ +
+
Parameter: +: 1. A string of zero or more decimal characters which + represent a single value. Leading zeros are ignored. The + decimal characters have a range of 0 (060) to 9 (071). +
2. The value so represented. +
+
Numeric Parameter: +: A parameter that represents a number, designated by Pn. +
+
Selective Parameter: +: A parameter that selects a subfunction from a + specified set of subfunctions, designated by Ps. In general, a + control sequence with more than one selective parameter causes + the same effect as several control sequences, each with one + selective parameter, e.g., CSI Psa; Psb; Psc F is identical to + CSI Psa F CSI Psb F CSI Psc F. +
+
Parameter String: +: A string of parameters separated by a semicolon. +
+
Default: +: A function-dependent value that is assumed when no explicit + value, or a value of 0, is specified. +
+
Final character: +: A character whose bit combination terminates an escape or control sequence. +

+ EXAMPLE: Control sequence to turn off all character attributes, then + turn on underscore and blink attributes (SGR). +

+ The octal representation of this string is: +

+     033 0133 060 073 064 073 065 0155
+    <ESC>   [   0   ;   4   ;   5    m
+

+ Alternate sequences which will accomplish the same thing: +

<ESC>[;4;m +
<ESC>[m +
<ESC>[4m +
<ESC>[5m +
<ESC>[0;04;005m +

DEC hacks

+ These form two groups of commands. +

+ In one first the first character is a hash (#) and the following a digit. + This command group is used to denote VT100 specific instructions and can + safely be sonsidered to be obsolete. See + DECALN, + DECDHLB, + DECDHLT, + DECDWL and + DECSWL. +

+ The second one is used to specify character set mappings (see SCS). A CSI instruction to do this is specified in ECMA, + and this should be used as a replacement. +

Appendix A - Notion Details
+

+ The following text is a collection of several sorts of definitions and + explainations. It is incomplete in many respects and a working draft. + + . +

+ All of the following control sequences are transmitted from the Host to + VT100 unless otherwise noted. All of the control sequences are a subset of + those defined in ANSI X 3.64 1977 and ANSI X 3.41 1974. +

+ The following text conforms to these formatting conventions: +

Individual character literals are set in bold face. Ascii representation + is used throughout, so ESC means the binary value of 27 and + [ a value of 91. +
+
Parameters are indicated by italic type faces. +

Parameter types usually are indicated as one of: + + + + +

Pn	A string of digits representing a numerical value.
Ps	A character that selects an item from a list.
a-z	Any lowercase sequence of one or more + characters represent a value to be + entered (as in Pn), and the name in the + will be referred to in explanatory text.

Spaces are used only to improve readability, they do not occure in the + control sequences unless otherwise indicated. +
+

+ The following attributes below have the following meaning: +

VT100 - This code is known to VT100. +
ANSI - This code is defined by ANSI. +
DEC - This code is DEC private. +
Command - Sent from host to the terminal. FIXME:add Inquiery. +
Reply - Sent from terminal to the host (as response to an Inquiery). +
Event - Sent from terminal to the host (caused by a user activity). +
Mode - The entry is a mode. +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

DECAWM +	Autowrap Mode +					VT100 +

	This is a private parameter to the SM and RM + control sequences. The + reset state prevents the cursor from moving when characters are + received while at the right margin. The set state causes these + characters to advance to the next line, causing a scroll up if required + and permitted. See MODES, SM, and + RM. +

DECCKM +	Cursor Keys Mode +					VT100 +

	This is a private parameter to the SM and RM + control requences. This + mode is only effective when the terminal is in keypad application mode + (DECKPAM) and the ANSI/VT52 mode (DECANM) + is set. Under these + conditions, if this mode is reset, the cursor keys will send ANSI + cursor control commands. If setm the cursor keys will send application + function commands. See MODES, RM, and + SM. +

DECCOLM +	Column Mode +					VT100 +

	3	VT100	emu	Ignore		Light LED 3
	4	VT100	emu	Ignore		Light LED 4

DECOM +	Origin Mode +					VT100 +

	This is a private parameter to SM and RM + control sequences. The reset + state causes the origin (or home position) to be the upper left + character position of the screen. Line and column numbers are, + therefore, independent of current margin settings. The cursor may be + positioned outside the margins with a cursor position (CUP) or + horizontal and vertical position (HVP) control. + + The set state causes the origin to be at the upper left character + position within the current margins. Line and column numbers are, + therefore, relative to the current margin settings. The cursor cannot + be positioned outside of the margins. + + The cursor is moved to the new home position when this mode is set or + reset. Lines and columns are numbered consecutively, with the origin + being line 1, column 1. +

DECRC +	Restore Cursor +					VT100 +

+	`ESC 8` +

On VT100
+

+ +The VT100 is an upward and downward software-compatible terminal; +that is, previous Digital video terminals have Digital's private standards +for control sequences. The American National Standards Institute has since +standardized escape and control sequences in terminals in documents X3.41-1974 +and X3.64-1977. +

+The VT100 is compatible with both the previous Digital standard and +ANSI standards. Customers may use existing Digital software designed around +the VT52 or new VT100 software. The VT100 has a "VT52 compatible" mode in +which the VT100 responds to control sequences like a VT52. In this mode, most +of the new VT100 features cannot be used. +

+Throughout this document references will be made to "VT52 mode" or +"ANSI mode". These two terms are used to indicate the VT100's software +compatibility. +

+NOTE: The ANSI standards allow the manufacturer flexibility in implementing +each function. This document describes how the VT100 will respond to the +implemented ANSI central function. +

+ +

+ + + + +
Modes
+

+ + + +The Following is a list of VT100 modes which may be changed with Set +Mode (SM) and Reset Mode (RM) controls. + +

Name	Pattern	Scope	Comment
Printable Ascii Characters	32..126	ASCII ECMA	This is the most original pattern of all. The characters to be + displayed are passed over the chanel and are interpreted by the + terminal (emulation) as instructions to display the corresponding + glyph of the ascii character set. Contempory emulations include the + upper half (128..255) of the extentions to the national ascii character + sets, also.
Ascii Control Characters	0..26,28..31,127	ASCII ECMA	Ascii defines some non-printable, but format effecting characters, too. + Depending on the emulation, at least some of them are given a meaning. + The typically implemented ones are those that are handled by a teletype + like device.
Simple Escape Sequence	ESC C	ECMA	These sequences are made up from an ESC character followed by + exactly one other character in the range ???..???.
CSI Sequence	ESC [ Parameters {I} C	ECMA
