<h2>Preface</h2> |
|
|
|
This document accompanies the Konsole and Kom programs, which are mainly terminal |
|
emulations. Since material about the extend and precise semantics of the emulatation |
|
intended by these programs is hard to find on the internet today, it came out |
|
nessesary to include a more precise specification within their release. |
|
<p> |
|
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. |
|
<p> |
|
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 extention |
|
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, |
|
<code>ansi.sys</code>, 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. |
|
<p> |
|
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. Especially the later makes the production of a <em>working</em> |
|
emulation an impossible task. And this is the place where this document steps in: |

|
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. |
|
<p> |
|
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. |
|
<p> |
|
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. |
|
<p> |
|
<em>NOTE</em>: 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. |

<em>All the following in this section is an outline</em>. <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. |

|
The control characters recognized by the VT100 are listed below. All |
|
other control characters cause no action to be taken. |
|
<p> |
|
Control characters (codes 00 - 037 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 the VT100. The processing of the control sequence then |
|
continues with the next character recieved. The exceptions are: if the <ESC> |
|
character occurs, the current control sequence is aborted, and a new one |
|
commences beginning with the <ESC> just recieved. If the character <CAN> |
|
(030) or the character <SUB> (032) 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. |

<h3>Definitions</h3> |
|
|
|
<dl> |
|
<dt>Control Sequence Introducer (CSI): |
|
<dd>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>[ |
|
|
|
<dt>Parameter: |
|
<dd>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). |
|
<br>2. The value so represented. |
|
|
|
<dt>Numeric Parameter: |
|
<dd>A parameter that represents a number, designated by Pn. |
|
|
|
<dt>Selective Parameter: |
|
<dd>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. |
|
|
|
<dt>Parameter String: |
|
<dd>A string of parameters separated by a semicolon. |
|
|
|
<dt>Default: |
|
<dd> A function-dependent value that is assumed when no explicit |
|
value, or a value of 0, is specified. |
|
|
|
<dt>Final character: |
|
<dd>A character whose bit combination terminates an escape or control sequence. |
|
</dl> |
|

<em>EXAMPLE</em>: Control sequence to turn off all character attributes, then |
|
turn on underscore and blink attributes (<a href=#SGR>SGR</a>). |

|
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. |
|
<p> |
|
The following text conforms to these formatting conventions: |
|
<ul> |
|
<li>Control characters are designated by angle brackets (e.g. |
|
the Escape character is <ESC>). |
|
|
|
<li>Parameters are indicated by curly braces. |
|
|
|
<li>Parameter types usually are indicated as one of: |
|
<table> |
|
<tr><td>{Pn} </td><td>A string of digits representing a numerical value.</td></tr> |
|
<tr><td>{Ps} </td><td>A character that selects an item from a list.</td></tr> |
|
<tr><td>{a-z}</td><td>Any lowercase sequence of one44 or more |
|
characters in braces represent a value to be |
|
entered (as in {Pn}), and the name in the |
|
braces will be referred to in explanatory text.</td></tr> |
|
</table> |
|
|
|
<li>Spaces in the control sequence are present for clarity and |
|
may be omitted. Spaces which are required will be |
|
surrounded by single quotes: ' '. |
|
|
|
<li>All other characters are literals. |

The United Kingdom and ASCII sets conform to the "ISO international |

register of character sets to be used with escape sequences". The |
|
other sets are private character sets. Special graphics means that the |

graphic characters fpr the codes 0137 to 0176 are replaced with other |
|
characters. The specified character set will be used until another SCS |

<em>NOTE 1</em>: Codes 0152-0156 and 0164-0170 are used to draw rectangular grids" each |
|
piece of this set is contiguous with other so the lines formed will be |
|
unbroken. |
|
<p> |
|
<em>NOTE 2</em>: Codes 0157-0163 give better vertical resolution than dashes and |
|
underlines when drawing graphs; using these segments, 120 x 132 resolution may |
|
be obtained in 132 column mode with the Advanced Video Option installed. |

<h3>Other Material</h3> |
|
<a href="nomailto:">Petri Virekoski</a> has posted much of |
|
this document to <a href="news:comp.terminals">comp.terminals</a> |
|
in 1993. It is largely derived from DEC document EK-VT100-UG-003, |
|
the original manual for the VT100. |
|
I htmlized and edited his posting in 1998 to provide the |
|
<code>Konsole</code> program with proper reference material. |
|
The original author is mentioned here only to honor his work, |
|
he has nothing to do with <code>Konsole</code>. Do not bother |
|
him with any questions. |
|
<p> |
|
Most so-called VT100 implementations (both stand-alone terminals and |
|
PC emulators) actually implement more controls than are given here. |
|
The minimal standard is really the slightly more advanced VT102 terminal. |
