These terminals (end points) where specialized devices, either + regular ttys (printer with keyboard) or later more sophisticated + things with cathode ray tubes. + <p> + <center><img src="konsole2.gif"></center> + <p> + 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. + <p> + 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. + <p> + 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. + <p> + 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. + <p> + 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. + <p> + <h2>A first refinement</h2> + <p> + 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. + <p> + 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. + <p> + 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. + <p> + The concrete model is often loosely named the "emulation", + the specific encoding chosen, the "protocol". + <p> + 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. + <p> + 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. + <p> + 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. + <p> + 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. + <p> + 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. + <p> + 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. + <p> + The full screen model basically adds the possibility to position + the cursor and to overwrite and clear the screen. + <p> + A plethora of additional (more or less useful) commands are + then added on this by every specific emulation, see below for + the awful details. + <p> + <!-- BEGIN: new section about the codes --> + <h2>Parts of the model</h2> + <p> + <it>All the following in this section is an outline</it>. + <p> + Parts of the terminal description + <ul> + <li>State + <br>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. + <li>Interface + <br>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. + <br>We have information flowing in both directions. On could destinguist + between: + <li>Commands + <br>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. + <li>Requests + <br>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. + <li>Events + <br>These are signals from the terminal caused by the user affecting the + mouse or keyboard to the host. + <li>Replys + <br>These are send by the terminal as a result of a Request from the hosts. + <li>Encoding/Decoding + </ul> + +Sequences.html + 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. + <p> + Refering both to their origin and form, one can group the overall encoding + schemes as follows: + <p> + <table> + <tr><td width=20% bgcolor=#d0d0d0>Name</td><td width=20% bgcolor=#d0d0d0>Pattern</td><td bgcolor=#d0d0d0>Scope</td><td bgcolor=#d0d0d0>Comment</td></tr> + <tr><td>Printable Ascii Characters</td><td>32..126</td><td>ASCII ECMA</td> + <td>This is the most original pattern of all.

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 <a href=#ESC>ESC</a> character occurs, the current control sequence + is aborted, and a new one commences beginning with the <a href=#ESC>ESC</a> + just received. If the character <a href=#CAN>CAN</a> (0x0c) or the + character <a href=#SUB>SUB</a> (0x0e) occurs, + the current control sequence is aborted.
