This is preliminary documentation for an upcoming version of Kermit 95 (3.0.0 Beta.8).
 

Kermit 95 Control Sequences

Kermit 95 Release: 3.0.0 DEV
Build Date: 15 May 2025

This document attempts to describe the control sequences implemented by Kermit 95s ANSI terminal emulator. It is roughly modeled on xterms excellent ctlseqs document to make comparing implemented control sequences easier. For quicker lookup, An Outline of this document is available, as well as a Table of Control Sequences by Terminal Type.

Prior to 2025 there was no documentation on the control sequences supported by Kermit 95. This document was produced by reading through several thousand lines of ANSI C recording what appeared to be implemented and what, if any, terminal type restrictions applied to various behaviors. There is sure to be errors, and many of the descriptions are unhelpfully brief.

Importantly, this document describes what Kermit 95 currently does (or appears to do) for a control sequence, not necessarily what it should do for a given control sequence and terminal emulation. There are no doubt bugs in Kermit 95s implementation of some escape sequences, and errors in this documents description of Kermit 95s implementation. If you notice any errors or omissions please log a bug to have it corrected! Its important to remember this is not documenting what real terminals do, just what Kermit 95s various modes do.

Kermit 95 emulates many different terminal types. Where a control sequence, or some specific behavior, is specific to one or more terminal types it is marked with badges such as these: vt320 wy370. Anything not marked with a terminal-type badge is available under all terminal type modes, even if a particular control sequence was not supported by a particular terminal.

Where possible, links to applicable standards and terminal documentation are provided. This is usually on the same line the section heading. This currently includes the following reference sources:

ecma-48
Standard ECMA-48: Control Functions for Coded Character Sets - both the PDF page number and document page number is given (e.g., p35/49—numbered page 35, PDF page 49)
dec-std-070
DEC STD 070 Video Systems Reference Manual (page numbers given are from the start of the PDF). Note that this is a very large OCRd PDF; it may take a while to load!
wy370
Wyse WY-370 Programmer's Guide (page numbers given are from the start of the PDF)
vt132
VT132 User Guide - both the PDF page number and document page number is given (e.g., p35/49—numbered page 35, PDF page 49)
vt420
DEC VT420 Reference Manual
vt510
DEC VT510 Video Terminal Programmer Information
vt52x
DEC VT520/VT525 Reference Manual
xterm
XTerm Control Sequences

K95s implementation will not always match the associated standards or terminal documentation. This could due to bugs (in K95 or in the terminals being emulated), or simply due to K95s implementation being incomplete.

Additional reference documentation that may be useful includes:

Application Program-Command functions

Kermit 95 supports the execution of Kermit commands via APC. As this could be hazardous, APC sequences are disabled by default and must be turned on with the slightly risky set term apc on command or the far more risky set term apc unchecked.

With APC sequences on, the remote host can request the execution of any Kermit command except those considered dangerous, such as push, run, !, redirect, delete, rename, output, enable, disable, script and set terminal apc.

The unchecked option removes the above safety mechanism allowing the remote host to run any Kermit command at all on your PC including those which could cause damage such as deleting files and disabling other security features.

You should only enable APC support when connecting to hosts you trust, and you should think twice about enabling unchecked APCs. See page 278 of Using C-Kermit for more on this topic.

Device-Control functions

DCS Ps ; Ps | Pt ST DECUDK — User Defined Keys dec-std-070 (p976) vt52x (p317) vt510 vt420 (p202/224) vt220 xterm

The first parameter can be either 0 (clear all UDK definitions before starting, default), or 1 (erase below).

The second parameter can be either 0 (lock the keys, default), or 1 (do not lock the keys)

The third parameter is a ;-seperated list of key definitions. A key definition consists of the key code for one of the function keys, a / character and then the string to send in response to that function key being pressed.

Not Implemented

K95 does not currently support specifying the shift-state of function keys, or the direction the response to pressing the key is to be sent in.

Kermit 95 Hyperlink Extension. This pre-dates the now widely implemented OSC 8 hyperlink escape sequence, but it works much the same way—you specify a destination for the hyperlink and some text. Where it differs from OSC 8 is that you can specify the type of hyperlink with both URI and UNC path destinations supported.

The parameter Ps specifies the type of link - a value of 1 indicates a URI to be opened in a browser (e.g., https://www.kermitproject.com), while a value of 2 indicates a UNC path to be opened in the file manager or the application associated with the file specified. A value of 0 is used to terminate a hyperlink.

The second parameter, Pt, is the destination in wrapped in quotes.

To start a hyperlink to https://www.kermitproject.com, issue the following sequence which begins the hyperlink and sets the destination: 

DCS 1 + m " h t t p s : / / w w w . k e r m i t p r o j e c t . c o m " ST

Then send the text for the hyperlink: 

K e r m i t   P r o j e c t   W e b s i t e

Then terminate the hyperlink with: 

DCS 0 + m ST

Linking to a UNC path is much the same: 

DCS 2 + m " \ \ m y s e r v e r \ s h a r e d " ST

Then send the text for the hyperlink: 

S h a r e d   F i l e s

Then terminate the hyperlink with: 

DCS 0 + m ST

DCS $ q Pt ST DECRQSS — Request Selection or Setting dec-std-070 (p451) vt52x (p266) vt510 vt420 (p267/289) xterm

vt320 vt320pc wy370

D...D specifies the setting or selection being requested - this usually consts of the final characters from whatever control sequence makes the setting or selection.

For example, to request the current SGR selection: 

DCS $ q m ST

And the response, DECRPSS, would be in the form 

DCS Ps $ r D...D ST

The parameter Ps in the response indicates if the original request was valid (1) or invalid (0) as described in DEC-STD-070. Despite what the VT320, VT420, VT510 and VT525 manuals say, this behavior is indeed correct. The VT320 manual got it the wrong way round, and the mistake was never caught, instead being carried forward all the way to the very end.

If the request was valid, D...D will contain the response.

For the earlier example requesting the current SGR selection, Kermit 95s response might be the following if bold, italic, and underline were all on: 

DCS 1 $ r 0 ; 1 ; 3 ; 4 m ST

Pt = m ⇒ SGR — Set Graphic Rendition dec-std-070 (p451) vt52x (p266) vt510 xterm

Returns currently selected graphic rendition. Only the following are currently reported: 0, 1, 2 (dim), 3, 4, 5 (slow blink), 7 (reverse video), 8, 30-37, 38 (rgb), 38 (indexed color), 40-47, 48 (rgb), 48 (indexed color), 90-97, 100-107.

Pt = " q ⇒ DECSCA — Set Character Attribute dec-std-070 (p451) vt52x (p266) vt510 xterm

Responds with the current state of DECSCA. For example, if DECSCA is set to Designate Character Erasable (2), then the response will be: DCS 1 $ r 1 " q ST

Pt = " p ⇒ DECSCL — Set Conformance Level dec-std-070 (p451) vt52x (p266) vt510 xterm

Reports the conformance level set with DECSCL, the result of which may be non-obvious!

A real DEC VT520 has two conformance levels: VT100 mode, and VT520 mode. So setting the conformance level to 62, 63, 64 or 65 will result in the conformance level being set to 65 giving you a response of DCS 1 $ r 6 5 ; 1 " p ST if using 7-bit controls. And if you set the conformance level to 61 (VT100), a real VT520 will not respond to DECRQSS because a real VT100 wouldn't.

As a result you'll only get a response on a VT320 or higher, and the conformance level will reflect the chosen terminal type. The only part of this response you can actually change via DECRQSS is the 8-bit/7-bit controls setting.

Pt = SP q ⇒ DECSCUSR — Set Cursor Style vt52x (p266) vt510 xterm

Reports the current DECSCUSR setting - the cursor style. A response for a blinking block, for example, looks like DCS 1 $ r 1 SP q ST (where SP is the space character)

Pt = r ⇒ DECSTBM — Set Top and Bottom Margins dec-std-070 (p451) vt52x (p266) vt510 xterm

Reports the current DECSTBM setting. For example, if the top margin is 5 and the bottom margin is 20 the response would be: DCS 1 $ r 5 ; 2 0 r ST

Pt = s ⇒ DECSLRM — Set Left and Right Margins dec-std-070 (p451) vt52x (p266) vt510 xterm

Not Implemented: K95 responds with: 

DCS 1 $ r s ST

Pt = t ⇒ DECSLPP — Set Lines Per Page dec-std-070 (p451) vt52x (p266) vt510 xterm

Reports the current DECSLPP setting - the number of lines in the terminal screen. A response for a terminal with a height of 24 lines looks like: DCS 1 $ r 2 4 t ST

Unlike a real terminal, Kermit 95s terminal height is not constrained to the options 24, 25, 36, 41, 42, 48, 52, 53 and 72. If your K95 terminal happens to be 10, or 100 lines tall that is the number Kermit 95 will respond with.

Pt = } ⇒ DECPRO

Not Implemented: K95 responds with: 

DCS 0 $ r } ST

Pt = $ | ⇒ DECSCPP — Set Columns Per Page dec-std-070 (p451) vt52x (p266) vt510 xterm

Kermit 95 responds with the width of the terminal Window. If, for example, the terminal is 132 columns wide, the response would be: DCS 1 $ r 1 3 2 $ | ST

Unlike a real terminal, Kermit 95s terminal width is not limited to being only 80 or 132 columns wide. If the terminal window is some other width, such as 200 columns, it will be reported here also.

Pt = $ } ⇒ DECSASD — Select Active Status Display dec-std-070 (p451) vt52x (p266) vt510 xterm

Responds with the current DECSASD selection. If DECSASD is set to Terminal (the default), the response would be: DCS 1 $ r 0 $ } ST

Pt = $ ~ ⇒ DECSSDT — Select Status Line Type dec-std-070 (p451) vt52x (p266) vt510 xterm

Responds with the current DECSSDT selection. If DECSSD is set to Indicator (the default), the response would be: DCS 1 $ r 1 $ ~ ST

Pt = ) { ⇒ DECSTGLT — Select Color Lookup Table vt52x (p266) xterm vt320 vt320pc wy370 s97801 aaa

DCS 1 $ q , } ST
                    DCS $ q 1 , } ST

And the response might be something like: DCS 1 $ r 1 ; 1 4 ; 4 , } ST

Pt = , } ⇒ DECATC — Alternate Text Color vt52x (p266) xterm vt320 vt320pc wy370 s97801 aaa

The response is the default background and foreground colors numbers separated by a space. The value of Ps should be 0, 1 or 2. Ps = 1 for the reverse color attribute, 0 or 2 for the normal attribute (2 should probably be the graphic attribute, but K95 doesn't do that currently).

In versions of Kermit 95 supporting color palettes larger than 16 colors, the current palette index will be returned exactly, so if a color &gt; 15 is set, then a color &gt; 15 will be returned. It is assumed that any application that sets a color outside the 16-color range will handle receiving a color outside this range. Otherwise, for the best compatibility stick to 16-color or RGB values for SET TERMINAL COLOR TERMINAL when using ANSI emulation.

In versions of Kermit 95 supporting 24-bit RGB color, if the default foreground or background color is a 24-bit RGB value, then the nearest color from the 16-color palette is returned regardless of the current palette setting.

scoansi

Margins are numbered 0-3 top/bottom/left/right.

The form of this control sequence ending with a `}` ( CSI = Ps ; Ps }) is marked with the comment "why this?" in the K95 source code - it is at this time uncertain if some particular terminal also accepts this form (or some particular application expects it), or if it is just a mistake/bug. Probably best not to rely on this behavior and instead use the one ending with `m`.

Sets all attributes to normal (off/false): blinking, italic, bold, invisible, underlined, reversed, graphic, dim, wyse, hyperlink, sco8bit.

scoansi at386 ansi Also sets crm to off/false.

Ps = 1 ⇒ Turn on Bold ecma-48 (p61/75) vt52x (p355) vt510 vt420 (p143/165) vt220 vt132 (p83/95) vt100 wy370 (p78) xterm

Turns on the Bold attribute. ECMA-48 leaves presentation up to the implementation saying it can be a bold font or increased intensity. Usually it was implemented as increased intensity on hardware terminals, and when color appeared it was often used to gain access to brighter versions of the standard eight colors specified by ECMA-48. SGR-90 to 97 and SGR-100 to 107 which provide direct access to these eight brighter colors are a later non-standard extension from IBMs aixterm terminal

In the Console version of Kermit 95 (OS/2, Windows), bold is always shown as a more intense color. The Windows GUI version of Kermit 95 (K95G) by default uses a bold font in addition to the more intense color.

Ps = 2 ⇒ Set Foreground and Background Colour scoansi

If processing of SGR colors is enabled (set term sgr-colors on), the following two parameters are taken as the foreground (first parameter) and background (second parameter) colors. The current intensity setting is preserved (if the previous foreground color was intense blue, and the new one is green, then the result will be intense green). Valid color codes are:

Value Color
0 Black
1 Blue
2 Green
3 Cyan
4 Red
5 Magenta
6 Brown
7 Light Grey

Ps = 2 ⇒ Turn on Faint/Dim ecma-48 (p61/75) wy370 (p78) xterm

Sets the foreground color to the supplied 24-bit RGB value. Pi is the color space ID which is currently ignored, and Pr/Pg/Pb are the red, green and blue components (0–255).

If Kermit 95 has not been compiled with 24-bit RGB color support, the nearest color in the current palette (as set by SET TERM COLOR PALETTE) is used instead. In console builds of Kermit 95 (k95.exe, k2.exe), this will always be the 16-color aixterm palette.

Ps = 38 : 5 : Ps ⇒ Set foreground to indexed color xterm

Sets the foreground color to the specified color in the current color palette (as set by SET TERM COLOR PALETTE). Valid range is 0–15 for the aixterm-16 palette, 0–87 for the xterm-88 palette, and 0–255 for the xterm-256 palette.

Console builds of Kermit 95 (k95.exe, k2.exe) only support the aixterm 16-color palette. If the current color palette is not aixterm-16, the specified color will be looked up in that palette, and then the nearest match in the aixterm-16 palette will be used instead.

This lets you switch in and out of VT100 mode, and change between 7-bit controls and 8-bit controls.

A real VT520 at least, and the documentation suggests this is the case for older models too, can only switch between the VT100 conformance level and its own conformance level. On a VT520, trying to set a conformance level of 62, 63, 64 or 65 will all get you 65. You get to choose between the lowest level (61) and the highest level for your terminal—the in between options are all the same as the highest level.

So the conformance levels you're switching to here depend on which terminal type Kermit 95 is emulating.

If Kermit 95 is emulating a VT320 or higher, you can query the state of DECSCL with with DECRQSS

You can query the current state of DECSTGLT with DECRQSS

Warning: The behavior of the implementation described here has not been checked against a real VT525 and as such is subject to change should it turn out the real terminal behaves differently.

Pt = 0 ⇒ Mono

Disables display of SGR colors. All text on screen and in the scrollback buffer immediately appears in the default terminal colors as set by SET TERMINAL COLOR TERMINAL.

While in this mode you can still use SGR to set colors, they just won't appear until display of SGR colors is re-enabled.

Pt = 1 ⇒ Alternate Color

Pt = 2 ⇒ Alternate Color

Uses the Bold, Underline, Reverse and Blink attributes to specify text colors from a table of 16 foreground-background color pairs, rather than showing text as bold/underline/reverse/blinking. Other text attributes (e.g., italic) are shown as normal text.

When in this mode, DECATCUM and DECATCBM can be set to allow text to be blinking and/or underlined in addition to the color associated with those attribute combinations.

To set colors for attribute combinations, see DECATC.

Pt = 3 ⇒ ANSI SGR color

Enables display of SGR colors. Returns display of reverse, underline, bold and blink attributes to their normal status.

CSI Ps $ | DECSCPP — Set Columns Per Page dec-std-070 (p328) vt52x (p279) vt510 vt420 (p130/152) xterm

The parameter Ps is required and specifies the new width of the terminal. Supplying 0, which should set the width to 80 columns, actually results in the terminal being set to the maximum width (512 columns on modern Windows, 256 on vintage windows and OS/2) - this is a bug.

The first parameter specifies the item the color is being assigned to, while the second and third parameters are the foreground and background color indices respectively.

While a real VT525 is limited to 16 colors (0...15), Kermit 95 accepts any color index that is valid for the current palette as chosen by SET TERMINAL COLOR PALETTE.

You can query the current state of DECAC with DECRQSS

Warning: The behavior described here has not been checked against a real VT525 and is subject to change should it turn out that a VT525 behaves differently.

Pt = 1 ⇒ Normal Text

Assigns the colors for normal text. This is the default text color for any text that hasn't had some other color specified via SGR or some other mechanism.

Pt = 2 ⇒ Window Frame

CSI Ps ; Ps ; Ps , } DECATC — Alternate Text Color vt52x (p176) xterm

vt320 vt320pc wy370 s97801 aaa

Sets colors used for text attribute combinations when in DECSTGLT Alternate Color Mode. The first parameter specifies an attribute combination from the table below, the second parameter is the foreground color index, and the third parameter is the background color index.

While a real VT525 limits you to the 16-color palette for the foreground and background color values, in Kermit 95 you can use any color from the current palette chosen with SET TERMINAL COLOR PALETTE.

DECATC only affects a separate table of colors that Kermit 95 maintains for use by the DECSTGLT Alternate Color Mode. These colors are not used when attributes are turned off via SET TERMINAL ATTRIBUTE, and except for the first five entries in the table they cannot be set via the SET TERMINAL COLOR command. The remaining eleven table entries can only be changed via DECATC. The DECATC color table is reset on terminal reset.

You can query the current state of DECATC with DECRQSS

Warning: Initial color assignments for these attribute combinations are subject to change! The current default color assignments are arbitrary and will likely change in the future if the proper assignments can be obtained from someone with access to a real VT525 for testing.

Operating System Commands

OSC Ps ; Pt BEL
OSC Ps ; Pt ST Set Text Parameters xterm

Kermit 95 supports a selection of operating system commands for setting the window title and manipulating color handling. These can be terminated with either an ST (OSC Ps ; Pt ST) or, for compatibility with other terminal emulators, a BEL (OSC Ps ; Pt BEL)

Ps specifies the type of operation:

Ps = 0 ⇒ Set Icon Name and Window Title (xterm) xterm

Sets the window title to the value supplied, up to 63 characters.

Ps = 1 ⇒ Change icon name xterm

Not supported: Windows doesn't provide a way of setting a value for the task bar label that is different from the window title.

Ps = 2 ⇒ Window title (xterm) xterm

Sets the window title to the value supplied, up to 63 characters.

Ps = 2L ⇒ DECSIN — Set Icon Title vt52x (p288)

Set Icon Title (VT520)

Not supported: Windows doesn't provide a way of setting a value for the task bar label that is different from the window title.

Ps = 3 ⇒ Set X property on top-level window xterm

Ps = 4 ; c ; spec ⇒ Change color number xterm

Changes the RGB value for one or more colors in the color palette. Multiple c ; spec pairs can be supplied separated by ';' to change multiple entries in the color palette. Only supported in GUI versions of Kermit 95.

The c component is the color index to change. Valid values depend on which color palette is currently active: 0–15 for aixterm-16, 0–87 for xterm-88, and 0–255 for xterm-256. The first five values above the range of the current palette (e.g., for the xterm-256 palette: 256, 257, 258, 259, 260) set attribute colors. See OSC-5 for more details.

The spec component is a color specification in the form supported by XParseColor. Both the newer rgb:RRRR/GGGG/BBBB and older #RRRRGGGGBBBB formats are supported, where R/G/B are hex digits (case doesn't matter). X11 color names are also accepted and parsed case-insensitively. For more information on this color specification, see the XParseColor man page, while a list of X11 color names and values can be found on Wikipedia. Other XParseColor formats such as rgbi: and CIEuvY: are not currently supported.

If the spec component is a '?' character then instead of setting a color for the specified color index, the current color is returned in the form of an OSC sequence suitable for restoring the current value. The returned OSC sequence uses the same terminator (BEL or ST) as the original query OSC sequence.

For example, OSC 4 ; 1 ; ? ST will cause K95 to send back OSC 4 ; 1 ; r g b : 0 0 0 0 / 0 0 0 0 / 8 0 8 0 ST for the default RGB value of 0/0/128 for color index 1. If multiple query parameters are supplied (eg OSC 4 ; 1 ; ? ; 2 ; ? ; 3 ; ? ST then multiple responses will be sent back.

If a color was set by name rather than an RGB value, then when queried that colors RGB value will be returned; Kermit 95 does not remember the original color name used.

Ps = 5 ; c ; spec ⇒ Change special color number xterm

Changes the foreground color (background color for reverse) of an attribute (special color in xterm), equivalent to SET TERM COLOR. Has no visible effect until that attribute is turned off ( OSC-6 or SET TERM ATTRIBUTE). In the case of Bold and Blink, the attribute must be turned off with SET TERM ATTRIBUTE {BOLD,BLINK} OFF COLOR (OSC-6 does this). Changes are reverted on terminal reset or via OSC-104/OSC-105.

Multiple c;spec pairs can be supplied in the same fashion as OSC-4, and the supported formats for spec are the same. The attributes that can be set are:

  • 0 - bold
  • 1 - underline
  • 2 - blink
  • 3 - reverse
  • 4 - italic

These values can also be set via OSC-4 by adding the above numbers to the maximum number of colors in the current palette (as set by SET TERM COLOR PALETTE). For example, if the current palette is xterm-256, then OSC 4 ; 257 ; r g b : f f f f / 0 0 0 0 / 0 0 0 0 would set the underline attribute to red.

Ps = 6 ; c ; f ⇒ Enable/disable special color number xterm

This is a synonym for OSC-106 (OSC-6 and OSC-106 have identical implementations).

Ps = 10 ⇒ Change VT100 text foreground color xterm

Requires one parameter: a new default foreground color, which does not take effect until attributes are set (eg, with SGR-0) and is reset on terminal reset. Format of the color parameter is the same color spec format as OSC-4 (rgb:RRRR/BBBB/GGGG), and if the text parameter is a `?` then the response will be an OSC-10 sequence to set the current color.

Up to nine additional color parameters can be supplied which will be applied to OSC-11 through OSC-19 in order. For example, the sequence \033]10;rgb:ffff/0000/0000;rgb:0000/ffff/0000\07 would set the foreground to red and background to green. If any of these parameters are `?`, they will be included in the query color response.

Ps = 11 ⇒ Change VT100 text background color xterm

Requires one parameter: a new default background color, which does not take effect until attributes are set (e.g., with SGR-0) and is reset on terminal reset. Format of the color parameter is the same color spec format as OSC-4 (rgb:RRRR/BBBB/GGGG), and if the text parameter is a `?` then the response will be an OSC-11 sequence to set the current color.

Up to eight additional color parameters can be supplied which will be applied to OSC-12 through OSC-19 in order.

Ps = 12 ⇒ Change text cursor color xterm

Requires one parameter: a new text cursor background color, which takes effect immediately and is reset on terminal reset. Format of the color parameter is the same color spec format as OSC-4 (rgb:RRRR/BBBB/GGGG), and if the text parameter is a `?` then the response will be an OSC-12 sequence to set the current color.

Up to seven additional color parameters can be supplied which will be applied to OSC-13 through OSC-19 in order.

Ps = 13 ⇒ Change pointer foreground color xterm

Not supported. Consumes one color parameter in the same color spec format as OSC-4 (rgb:RRRR/BBBB/GGGG), but does not apply it to anything as K95 does not support changing the pointer color.

Up to six additional color parameters can be supplied which will be applied to OSC-14 through OSC-19 in order.

Ps = 14 ⇒ Change pointer background color xterm

Not supported. Consumes one color parameter in the same color spec format as OSC-4 (rgb:RRRR/BBBB/GGGG), but does not apply it to anything as K95 does not support changing the pointer color.

Up to five additional color parameters can be supplied which will be applied to OSC-15 through OSC-19 in order.

Ps = 15 ⇒ Change tektronix foreground color xterm

Not supported. Consumes one color parameter in the same color spec format as OSC-4 (rgb:RRRR/BBBB/GGGG), but does not apply it to anything as K95 does not support Tektronix emulation.

Up to four additional color parameters can be supplied which will be applied to OSC-16 through OSC-19 in order.

Ps = 16 ⇒ Change tektronix background color xterm

Not supported. Consumes one color parameter in the same color spec format as OSC-4 (rgb:RRRR/BBBB/GGGG), but does not apply it to anything as K95 does not support Tektronix emulation.

Up to three additional color parameters can be supplied which will be applied to OSC-17 through OSC-19 in order.

Ps = 17 ⇒ Change highlight background color xterm

Sets the window title to the value supplied, up to 63 characters.

Ps = 104 ; c ⇒ Reset color number xterm

Resets one or more colors in the color palette to defaults or values specified by the user via SET GUI RGBCOLOR. Multiple color numbers can be specified separated by ';' (e.g., OSC 1 0 4 ; 1 ; 2 ; 3 ST). Only supported in GUI versions of Kermit 95.

If no parameters are given (eg, OSC 104 ST), then the entire color palette is reset.

The first five color numbers above the range of the current palette allow resetting attribute colors in the same way OSC-4 allows setting attribute colors. OSC-104 will not reset all attribute colors in the absence of any parameters however; for that OSC-105 must be used.

Ps = 105 ; c ⇒ Reset special color number xterm

Resets one or more attribute colors (special colors in xterm) to their default/user set values. Any number of colors can be specified using the same numberas as for OSC-5. If none are specified, all attribute colors are reset.

Ps = 106 ; c ; f ⇒ Enable/disable special color number xterm

Enables rendering attributes as color (special color in xterm)—equivalent to SET TERM ATTRIBUTE x OFF or, in the case of blink and bold, SET TERM ATTRIBUTE {BLINK,BOLD} OFF COLOR.

The c parameter is the attribute to enable or disable, and the second parameter, f is if it should be disabled (0) or enabled and shown as color (any other value):

  • 0 - bold
  • 1 - underline
  • 2 - blink
  • 3 - reverse
  • 4 - italic
  • 5 - colorAttMode

The colorAttMode (off by default in xterm, on by default in Kermit 95) controls whether attribute colors (when enabled) take priority over SGR colors. When OFF, only text that has the same color as the default attribute (settable with DECAC, SNF, SNB, OSC-10/11, etc.) will show in its attribute color. When ON, it will show in its attribute color regardless of whether some other SGR color was assigned to that text.

Ps = 110 ⇒ Reset VT100 text foreground color xterm

Ps = 111 ⇒ Reset VT100 text background color xterm

Ps = 112 ⇒ Reset text cursor color xterm

Ps = 113 ⇒ Reset pointer foreground color xterm

Ps = 114 ⇒ Reset pointer background color xterm

Ps = 115 ⇒ Reset tektronix foreground color xterm

Ps = 116 ⇒ Reset Tektronix background color xterm

Ps = 117 ⇒ Reset highlight color xterm

Ps = 118 ⇒ Reset tektronix cursor color xterm

Ps = 119 ⇒ Reset highlight foreground xterm

Ps = I ; c ⇒ Set icon to file xterm

Not supported as the specified icon file specification is likely to reside on a remote host which K95 has no reasonable way of accessing.

Ps = l ; c ⇒ set Window title xterm

Sets the window title to the value supplied, up to 63 characters.

Ps = L ; c ⇒ set icon label xterm

Not supported: Windows doesn't provide a way of setting a value for the task bar label that is different from the window title.

Ps = R ⇒ Reset palette (linux) linux

This OSC is not terminated! At all! The OSC is, verbatim, OSC R. No ST or BEL to terminate! For this reason its limited to the linux terminal type.

In GUI versions of Kermit 95, this resets all color palettes to defaults or values specified by the user via SET GUI RGBCOLOR. In console versions, this OSC is not acted upon.

Ps = P nrrggbb ⇒ Set palette (linux) linux

This OSC is not terminated! At all! No ST or BEL to terminate! For this reason its limited to the linux terminal type.

In GUI versions of Kermit 95, this sets the RGB value for color index n (0–15 in hex) to the RGB value rrggbb (0–255 in hex). In console versions of Kermit 95, this OSC is not acted upon.

Color Support in Kermit 95

Prior to Kermit 95 v3.0 beta.8, Kermit 95 was limited to 16 colors (the 8 standard ANSI colors, plus the additional 8 "intense" colors from aixterm). Kermit 95 now supports being built with multiple distinct color palettes and 24-bit RGB support:

The first 16 colors are the same in each palette. You can change the currently active color palette via the SET TERM COLOR PALETTE command. This setting is primarily for the GUI version of K95 and affects:

As Kermit 95 does not store a palette ID alongside each color attribute (this would waste too much RAM), changing the active color palette has an immediate effect on the current contents of the terminal and the scroll-back buffer. Switching from a larger palette to a smaller one mid-session will result in incorrect colors being displayed. As this is just a rendering setting, switching back to the previous palette will imediately restore correct color for the terminal screen and scrollback buffer.

The color related build options primarily affect the size of the data structure used for storing color information for each cell in the terminal buffer:

24-bit RGB support

If Kermit 95 was not compiled with 24-bit RGB support, or the current color palette is not one with RGB support (something other than xterm-rgb), Kermit 95 uses color quantization to select the nearest color in the current color palette to 24bit RGB colors set via SGR-38 and SGR-48. That palette color is then stored, rather than the RGB value.

As Kermit 95 uses the same data structure for storing attributes-as-colors (special colors in xterm) as it does for storing color attributes in the terminal buffer, Kermit 95 only supports OSC-5 (Change special color number) when built with 24-bit RGB support as OSC-5 does not support setting color indexes, only RGB values.

To help applications on the remote host detect 24-bit color support, Kermit 95 will automatically set the COLORTERM environment variable to truecolor on the remote host when making a telnet or SSH connection. In the unlikely event this behavior causes problems, it can be disabled for telnet connections with SET TELNET SEND-COLORTERM OFF. For SSH connections there is no disable option as SSH servers will usually reject this environment variable by default unless its added to AcceptEnv in /etc/ssh/sshd_config

Customising the Color Palette

GUI versions of Kermit 95 keep two copies of each color palette in memory: the active copy, and the saved copy. When Kermit 95 is launched, both copies contain the same data. At any time, you can change the RGB value in both copies of the current color palette with the SET GUI RGBCOLOR command, and the active copy of the current color palette only with OSC-4 or (for the linux terminal type) OSC-P.

When the terminal is reset, the active copies of all color palettes are overwritten by their saved copies. This results in changes made via OSC-4 being undone without affecting changes made via SET GUI RGBCOLOR.

As SET GUI RGBCOLOR and OSC-4 only affect the current palette, if you make a change while the aixterm-16 palette is selected you only made a change to the definition of the aixterm-16 palette specifically. If you switch to the xterm-256 palette, your change will not be visible until you switch back to the aixterm-16 palette.

Color in Console versions of Kermit 95

Console builds of Kermit 95 (or custom 16-color builds of GUI Kermit 95) only support 16 colors max. This is a limitation in the OS/2 VIO Window, and the Windows NT/9x console host prior to Windows 10 v1809. This is stored as a pair of 4-bit values packed into an 8-bit integer.

Console versions of Kermit 95 have no control over the appearance of these 16 colors; that is up to the console environment K95 is running under. Because of this, console builds of K95 do not support customizing the color palette via OSC-4 or SET GUI RGBCOLOR.

To retain compatibility with software blindly expecting 256-color or 24-bit RGB color support, 16-color versions of Kermit 95 still support the SET TERM COLOR PALETTE command and implement SGR-38 and SGR-48. When the host tries to set a color via SGR-38 or SGR-48, that request is translated into something valid for the aixterm-16 color palette.

If a color index was specified for SGR-38 or SGR-48, then the RGB value for that color is looked up in the current color palette, then the aixterm-16 palette is searched for the nearest match to that RGB value. If a 24bit RGB value was specified for SGR-38 or SGR-48, then the aixterm-16 palette is searched for the nearest match to that RGB value.

Once the nearest match in the aixterm-16 palette is found, that color index is then stored rather than the supplied index or RGB value. To not waste memory storing color indexes the console environment can't actually display, 16-color builds of K95 only have 4 bits each for the foreground and background colors, making them incapable of actually storing color indexes above 16 or per-cell RGB values.

16-color builds do not support OSC-4 or the SET GUI RGBCOLOR command as the color palettes are only used to get an RGB value to use for color quantization. K95 has no control over how the console host/VIO window renders colors, so the RGB values in the color palettes are never used for display; only to map indexes from a larger palette on to the smaller 4-bit aixterm-16 palette.
