Villanova University
Campus Computing - Terminal Emulation
Includes VT100 and VT52 Terminal and Control Codes
This file tqcontains 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.
Thank you,
Jim McRee (209507097@VUVAXCOM.BITNET)
(* ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** *)
CONTROL SEQUENCE SUMMARY
* For additional information on the DEC VT100 and VT102 terminals, please
consult the VT100 USER GUIDE and VT102 USER GUIDE, published by Digital
Equipment Corporation as part numbers EK-VT100-UG and EK-VT102-UG.
CONTROL CHARACTERS:
------------------
Character
Name Decimal Action Taken
---------------------------------------------------------------
NUL 0 Fill character; ignored on input.
ENQ 5 Transmit answerback message.
BEL 7 Ring the bell.
BS 8 Move cursor left.
HT 9 Move cursor to next tab stop.
LF 10 Line feed; causes print if in autoprint.
VT 11 Same as LF.
FF 12 Same as LF.
CR 13 Move cursor to left margin or newline.
SO 14 Invoke G1 character set.
SI 15 Invoke G0 character set.
XON 17 Resume transmission.
XOFF 19 Halt transmission.
CAN 24 Cancel escape sequence and display checkerboard.
SUB 26 Same as CAN.
ESC 27 Introduce a control sequence.
DEL 127 Fill character; ignored on input.
* All characters less than 32 decimal which are not listed above are ignored.
(* ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** *)
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.
CURSOR MOVEMENT:
---------------
Cursor Up: Esc [ Pn A
Cursor Down: Esc [ Pn B
Cursor Left: Esc [ Pn C
Cursor Right: Esc [ Pn D
Direct Addressing : Esc [ Pn(row);Pn(col);H or
Esc [ Pn(row);Pn(col);f
ie. (Pascal)
Writeln (Esc,'[',Row:1,';',col:1,';','H');
Index: Esc D
New Line: Esc E
Reverse Line: Esc M
Save cursor & Attributes: Esc 7
Restore cursor & attributes: Esc 8
ERASING:
-------
Cursor to end of line Esc [ K
Beginning of line to cursor Esc [ 1 K
Entire line Esc [ 2 K
Cursor to end of screen Esc [ J
Beginning of screen to cursor Esc [ 1 J
Entire screen Esc [ 2 J
(Some programs expect Esc [ J to always clear the entire
screen, but this does not conform to the standard.)
MODES:
-----
Set with Esc [ Ps h
Reset with Esc [ Ps l
Mode name Ps Set Reset
-------------------------------------------------------------------
Keyboard action 2 Locked Unlocked

EDITING:

PRINTING:
--------
Print screen or region Esc [ i
Print cursor line Esc [ ? 1 i
Enter auto print Esc [ ? 5 i
Exit auto print Esc [ ? 4 i
Enter print controller Esc [ 5 i
Exit print controller Esc [ 4 i
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.

Height Width _Line Blink Side Inverse Shade Escape Code

No No No Yes Normal No Normal <ESC>#7<ESC>[5m
No No No No Normal Yes Normal <ESC>#7<ESC>[7m
* Some codes have been eliminated due to a repetition of effects. To the best
of my knowledge, these codes are complete and correct. If you should find
any errors, or you find some new sequences/effects, please inform me.
* <ESC>#3 and <ESC>#4 behave in the same way as <ESC>#3[3m and <ESC>#4[4m.

(* ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** *)
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.
Transmit a file Esc { T filenameCR ---> CR = Carriage Return
Receive a file Esc { R filenameCR ---> CR = Carriage Return
Append to a file Esc { A filenameCR ---> CR = Carriage Return
Save collected text Esc { S
Save collected text Esc S
* These sequences will probably be most useful in developing a micro
version of a VT100 emulator or in adapting an existing one.

VT100 CURRENT STATES:
--------------------
Esc [ c DA:Device Attributes
or
Esc Z DECID:Identify Terminal (ANSI mode)
* For PC/Intercomm and some other emulators,
irrespective of the parameter(s) present, the
response is always
Esc [ ? 6 c
(i.e., a VT102) Other DEC terminals will respond
according to their configuration and mode.
Esc Z Identify (VT52 mode)
* The sequence Esc / Z is always returned.
Esc [ <sol> x DECREQTPARM: Request Terminal Parameters
* <sol> values other than 1 are ignored. Upon
receipt of a <sol> value of 1, the following
response is sent:
Esc[3;<par>;<nbits>;<xspeed>;<rspeed>;1;0x
* Where <par>, <nbits>, <xspeed>, and <rspeed>
are as for VT100s with the following
exceptions:
<nbits> Values of 5 and 6 bits per
character are sent as 7 bits.
<xspeed>,<rspeed>
These two numbers will always
be the same. 9600 baud is
sent for 7200 baud.
Esc [ Ps n DSR: Device tqStatus Report
* Parameter values other than 5, 6, are ignored.
If the parameter value is 5, the sequence
Esc [ O n is returned. If the parameter value is
6, the CPR: Cursor Position Report sequence
Esc [ Pn ; Pn R is returned with the Pn set to
cursor row and column numbers.
