Includes VT100 and VT52 Terminal and Control Codes
|
|
|
|
|
|
|
|
|
|
This file contains control and terminal codes for the VT100 terminals,
|
|
|
|
|
ANSI terminals, and VT52 terminals. Many of the codes were derived from PC/
|
|
|
|
|
Intercomm, from Mark of the Unicorn Software. I have researched some of them
|
|
|
|
|
and added some of my own.

ANSI MODE SUMMARY:

|
|
*In ANSI sequences, parameters are given as a string of ASCII digits
|
|
|
|
|
('0' - '9') seperated by semicolons. Pn refers to a number whose value
|
|
|
|
|
used directly. Ps refers to a number used as a selector.

LINE SIZE:

|
|
---------
|
|
|
|
|
|
|
|
|
|
The following is a list of the available styles of printing on the
|
|
|
|
|
screen. "Yes" in any column means that the option is supported by the escape
|
|
|
|
|
code on that line. "No" means that the option is not supported by the escape
|
|
|
|
|
code on that line; however, it may, and almost certainly is, supported by
|
|
|
|
|
another escape sequence.
|
|
|
|
|
|
|
|
|
|
Double-height and double-width double the size of the characters in their
|
|
|
|
|
respective ways (ie. Double-height is twice as tall as usual). _Line
|
|
|
|
|
designates underlining. Blink is for blinking characters. Side is the
|
|
|
|
|
orientation of the character. Normal means that there is no orientation.
|
|
|
|
|
|
|
|
|
|
Top and bottom refers to the position of the character in order to make a
|
|
|
|
|
complete character. The top and bottom sequences will be important if you use
|
|
|
|
|
the double height option. You will need to print the line twice to get a
|
|
|
|
|
complete line. The first printing will print the top part of the characters
|
|
|
|
|
and the second printing will print the bottom part.
|
|
|
|
|
|
|
|
|
|
Inverse refers to the condition of the character. "No" indicates that the
|
|
|
|
|
character will be printed in the color it normally is printed in with its usual
|
|
|
|
|
backround. "Yes" means that the character will be printed in the backround
|
|
|
|
|
color and the character's backround will be the color it is usually printed in.
|
|
|
|
|
Shade refers to the brightness of the character. Normal is the standard
|
|
|
|
|
brightness of the character. Bright is bold type. Dark is a darker brightness
|
|
|
|
|
than usual.
|
|
|
|
|
|
|
|
|
|
The escape code is the command you would type before the text you want to print
|
|
|
|
|
to get the indicated effects. This section was greatly expanded in version 1.1
|
|
|
|
|
of this file.

NON-VT100 CONTROL SEQUENCES:

|
|
|
----------------------------
|
|
|
|
|
|
|
|
|
|
*Some VT100 terminal programs also understand a few other escape
|
|
|
|
|
sequences than the standard VT100. I cannot guarantee that any of
|
|
|
|
|
these nonstandard codes will work with any particular terminal, but
|
|
|
|
|
they may be useful if they do work.

|
|
version of a VT100 emulator or in adapting an existing one.
