.Sh "Control Bytes, Characters, and Sequences"
.LP
2019-02-24 04:41:42 -07:00
ECMA-48 (aka \*(``ISO 6429\*('') documents C1 (8-bit) and C0 (7-bit) codes.
Those are respectively codes 128 to 159 and 0 to 31.
ECMA-48 avoids referring to these codes as characters,
because that term is associated with \fIgraphic characters\fP.
Instead, it uses \*(``bytes\*('' and \*(``codes\*('',
with occasional lapses to \*(``characters\*(''
where the meaning cannot be mistaken.
.LP
Controls (including the escape code 27) are processed once:
.bP
This means that a C1 control can be mistaken for badly-formed UTF-8
when the terminal runs
in UTF-8 mode because C1 controls are valid \fIcontinuation bytes\fP of
a UTF-8 encoded (multibyte) value.
.bP
It is not possible to use a C1 control obtained from decoding the UTF-8 text,
because that would require reprocessing the data.
Consequently there is no ambiguity in the way
this document uses the term \*(``character\*('' to refer to
bytes in a control sequence.
.LP
The order of processing is a necessary consequence of the way ECMA-48
is designed:
.bP
Each byte sent to the terminal can be unambiguously determined to
fall into one of a few categories (C0, C1 and graphic characters).
.bP
ECMA-48 is \fImodal\fP; once it starts processing a control sequence,
the terminal continues until the sequence is complete,
or some byte is found which is not allowed in the sequence.
.bP
Intermediate, parameter and final bytes may
use the same codes as graphic characters,
but they are processed as part of a control sequence and are not actually
graphic characters.
.bP
Eight-bit controls can have intermediate, etc., bytes in the range 160 to 255.
Those can be treated as their counterparts in the range 32 to 127.
.bP
Single-byte controls can be handled separately from multi-byte
control sequences because ECMA-48's rules are unambiguous.
.IP
As a special case, ECMA-48 (section 9) mentions that the control functions
shift-in and shift-out are allowed to occur within a 7-bit multibyte control
sequence because those cannot alter the meaning of the control sequence.
.bP
Some controls (such as \*(Os) introduce a string mode,
which is ended on a \*(ST (string terminator).
.IP
2019-02-24 04:41:42 -07:00
ECMA-48 describes only correct behavior,
telling what types of characters are expected
at each stage of the control sequences.
It says that the action taken in error recovery is implementation-dependent.
\fI\*(XT\fP decodes control sequences using a state machine.
It handles errors in decoding
i.e., unexpected characters,
by resetting to the initial (ground) state.
That is different from the treatment of unimplemented
(but correctly formatted) features.
.IP
If an application does not send the string terminator, that is also an error
from the standpoint of a user.
To accommodate users of those applications, \fI\*(xt\fP has resource
settings which allow workarounds:
.RS
.bP
The Linux console's palette sequences do not use a string terminator.
The \fBbrokenLinuxOSC\fP resource setting tells \fI\*(xt\fP to ignore
those particular sequences.
.bP
The terminal should accept single-byte controls within the string.
But some applications omit a string terminator,
like the Linux console.
The \fBbrokenStringTerm\fP resource setting tells \fI\*(xt\fP to exit
string mode if it decodes a common control character such as carriage return
before the string terminator.

2019-02-24 04:41:42 -07:00
The \fI\*(xt\fP program recognizes both 8-bit and 7-bit control characters.
2006-11-26 04:11:12 -07:00
It generates 7-bit controls (by default) or 8-bit if S8C1T is enabled.

In this document, \*(``VT100\*('' refers not only to VT100/VT102,
but also to the succession of upward-compatible terminals produced
by DEC (Digital Equipment Corporation)
from the mid-1970s for about twenty years.
For brevity, the document refers to the related models:
\*(``VT200\*('' as VT220/VT240,
\*(``VT300\*('' as VT320/VT340,
\*(``VT400\*('' as VT420, and
\*(``VT500\*('' as VT510/VT520/VT525.
.LP
2006-11-26 04:11:12 -07:00
Most of these control sequences are standard VT102 control sequences,
but there is support for later DEC VT terminals
(i.e., VT220, VT320, VT420, VT510),
2019-02-24 04:41:42 -07:00
as well as ECMA-48 and \fIaixterm\fP color controls.
The only VT102 feature not supported is auto-repeat,
2006-11-26 04:11:12 -07:00
since the only way X provides for this will affect all windows.
.LP
2006-11-26 04:11:12 -07:00
There are additional control sequences to provide
2019-02-24 04:41:42 -07:00
\fI\*(xt-\fPdependent functions, such as the scrollbar or window size.
Where the function is specified by DEC or ECMA-48, the code assigned
to it is given in parentheses.
.LP
The escape codes to designate and invoke
character sets are specified by ISO 2022 (see that document for a
discussion of character sets).
.LP
Many of the features are optional;
\fI\*(xt\fP can be configured and built without support for them.

The VT220 character sets,
together with a few others (such as Portuguese) are activated by
the National Replacement Character Set (NRCS) controls.
The term \*(``replacement\*('' says that the character set is formed
by replacing some of the characters in a set
(termed the \fIMultinational Character Set\fP)
with more useful ones for a given language.
The ASCII and DEC Supplemental character sets make up the two
halves of the Multinational Character set,
initially mapped to GL and GR.
.br
The valid final characters \*(Cc for this control are:
\*(Cc = \*A \(-> United Kingdom (UK), VT100.
\*(Cc = \*(cB \(-> United States (USASCII), VT100.
\*(Cc = \*4 \(-> Dutch, VT200.
\*(Cc = \*C or \*5 \(-> Finnish, VT200.
\*(Cc = \*R or \*f \(-> French, VT200.
\*(Cc = \*Q or \*9 \(-> French Canadian, VT200.
\*(Cc = \*K \(-> German, VT200.
\*(Cc = \*(Dq\*> \(-> Greek, VT500.
\*(Cc = \*%\*= \(-> Hebrew, VT500.
\*(Cc = \*Y \(-> Italian, VT200.
\*(Cc = \*`, \*E or \*6 \(-> Norwegian/Danish, VT200.
\*(Cc = \*%\*6 \(-> Portuguese, VT300.
\*(Cc = \*Z \(-> Spanish, VT200.
\*(Cc = \*H or \*7 \(-> Swedish, VT200.
\*(Cc = \*= \(-> Swiss, VT200.
\*(Cc = \*%\*2 \(-> Turkish, VT500.
.br
The final character \*A is a special case,
since the same final character is
used by the VT300-control for the 96-character British Latin-1.
.br
There are a few other 94-character sets:
\*(Cc = \*0 \(-> DEC Special Character and Line Drawing Set, VT100.
\*(Cc = \*< \(-> DEC Supplemental, VT200.
\*(Cc = \*> \(-> DEC Technical, VT300.
.br
These are documented as NRCS:
\*(Cc = \*%\*5 \(-> DEC Supplemental Graphics, VT300.
\*(Cc = \*&\*4 \(-> DEC Cyrillic, VT500.
\*(Cc = \*(Dq\*? \(-> DEC Greek, VT500.
\*(Cc = \*(Dq\*4 \(-> DEC Hebrew, VT500.
\*(Cc = \*%\*0 \(-> DEC Turkish, VT500.
.br
The VT520 reference manual lists a few more,
but no documentation has been found for the mappings:
\*(Cc = \*&\*5 \(-> DEC Russian, VT500.
\*(Cc = \*%\*3 \(-> SCS NRCS, VT500.

The current implementation allows reading the graphics sizes,
but disallows modifying those sizes because that is done once,
using resource-values.
.bP
2019-02-24 04:41:42 -07:00
Graphics geometry is not necessarily the same as \*(``window size\*(''
(see the dtterm window manipulation extensions).
For example, \fI\*(xt\fP limits the maximum graphics geometry at compile time
2017-07-15 13:20:51 -06:00
(1000x1000 as of version 328)
although the window size can be larger.
.bP
While resizing a window will always change the current
graphics geometry, the reverse is not true.
Setting graphics geometry does not affect the window size.

Some of the above note the edition of ECMA-48 which first describes
a feature.
In its successive editions from 1979 to 1991
(\fI2nd\fP 1979, \fI3rd\fP 1984, \fI4th\fP 1986, and \fI5th\fP 1991),
ECMA-48 listed codes through \*6\*5
(skipping several toward the end of the range).
Most of the ECMA-48 codes not implemented in \fI\*(xt\fP
were never implemented in a hardware terminal.
Several (such as \*3\*9 and \*4\*9) are either noted in ECMA-48
as implementation defined, or described in vague terms.
.sP
The successive editions of ECMA-48 give little attention to
changes from one edition to the next,
except to comment on features which have become obsolete.
ECMA-48 1st (1976) is unavailable;
there is no reliable source of information which states whether
\*(``ANSI\*('' color was defined in that edition,
or later (1979).
The VT100 (1978) implemented the most commonly used non-color video attributes
which are given in the 2nd edition.
.sP
2019-02-24 04:41:42 -07:00
While 8-color support is described in ECMA-48 2nd edition,
the VT500 series (introduced in 1993)
were the first DEC terminals implementing \*(``ANSI\*('' color.
The DEC terminal's use of color is known to differ from \fI\*(xt\fP;
useful documentation on this series
became available too late to influence \fI\*(xt\fP.

If 16-color support is compiled, the following \fIaixterm\fP controls apply.

are set so that the ISO color codes are the first 8 of a set of 16.
Then the \fIaixterm\fP colors are the bright versions of the ISO colors:

Many keyboards have keys labeled \*(``Alt\*(''.
Few have keys labeled \*(``Meta\*(''.
However, \fI\*(xt\fP's default translations use the \fIMeta\fP modifier.
Common keyboard configurations assign the \fIMeta\fP modifier
to an \*(``Alt\*('' key.
2007-06-15 13:29:55 -06:00
By using \fIxmodmap\fP one may have the modifier assigned to a different key,
2019-02-24 04:41:42 -07:00
and have \*(``real\*('' alt and meta keys.

The codes used for the \fIPC-style function keys\fP were inspired
by a feature of the VT510, referred to in its reference manual as DECFNK.
In the DECFNK scheme, codes 2-8 identify modifiers for function-keys
and cursor-, editing-keypad keys.
Unlike \fI\*(xt\fP, the VT510 limits the modifiers which can be used
with cursor- and editing-keypad keys.
Although the name \*(``DECFNK\*('' implies that it is a mode,
the VT510 manual mentions it only as a feature,
which (like \fI\*(xt\fP) interacts with the DECUDK feature.
Unlike \fI\*(xt\fP, VT510/VT520 provide an extension to DECUDK
(DECPFK and DECPAK)
which apparently was the reason for the feature in those terminals,
i.e., for identifying a programmable key
rather than making it simple for applications to obtain modifier information.
It is not described in the related VT520 manual.
Neither manual was readily available
at the time the feature was added to \fI\*(xt\fP.
.LP
On the other hand, the VT510 and VT520 reference manuals
do document a related feature.
That is its emulation of the SCO console,
which is similar to the \*(``xterm-sco\*('' terminal description.
The SCO console function-keys are less useful to
applications developers than the approach used by \fI\*(xt\fP because
.bP
the relationship between modifiers and the characters sent by function-keys
is not readily apparent, and
.bP
the scheme is not extensible, i.e., it is an \fIad hoc\fP
asssignment limited to two modifiers (\fIshift\fP and \fIcontrol\fP).

Most full-screen applications use terminfo or termcap to obtain
strings used to start/stop full-screen mode,
i.e., \fIsmcup\fP and \fIrmcup\fP for terminfo,
or the corresponding \fIti\fP and \fIte\fP for termcap.
The \fBtiteInhibit\fP resource removes the \fIti\fP and \fIte\fP strings
from the TERMCAP string which is set in the environment for some platforms.
2019-02-24 04:41:42 -07:00
That is not done when \fI\*(xt\fP is built with terminfo libraries because
2006-11-26 04:11:12 -07:00
terminfo does not provide the whole text of the termcap data in one piece.
It would not work for terminfo anyway, since terminfo data is not passed

As a VT220-emulator, \fI\*(xt\fP \*(``should\*('' limit
the character encoding for

Indeed, it used to be the case (and was documented) that
window titles had to be ISO-8859-1.
This is no longer the case.
However, there are many applications which still assume that titles are
set using ISO-8859-1.
So that is the default behavior.
2019-02-24 04:41:42 -07:00

If \fI\*(xt\fP is running with UTF-8 encoding,
it is possible to use window- and icon-labels encoded using UTF-8.

The \fButf8Title\fP X resource setting tells \fI\*(xt\fP to disable
a reconversion of the title string back to ISO-8859-1,

The same feature can be enabled using the title mode control sequence
described in this summary.

Separate from the ability to set the titles,

2019-02-24 04:41:42 -07:00
This choice is available only while \fI\*(xt\fP is using UTF-8 encoding.

Finally, the characters sent to, or returned by a title control

To make them more manageable (and constrained), for use in shell scripts,
2019-02-24 04:41:42 -07:00

Note however that the shift and control bits are normally unavailable
2019-02-24 04:41:42 -07:00

Wheel mice may return buttons 4 and 5.
Those buttons are represented by the same event codes

Release events for the wheel buttons are not reported.
By default,
the wheel mouse events are translated to \fIscroll-back\fP

Past button 11, the encoding is ambiguous because the same code

\fI\*(xt\fP also reports button-motion events.
Motion events
2006-11-26 04:11:12 -07:00
are reported only if the mouse pointer has moved to a different character
cell.
It is enabled by specifying parameter 1002 to DECSET.

2019-02-24 04:41:42 -07:00

The original X10 mouse protocol limits the \*(Cx and \*(Cy ordinates
to 223 (=255\ -\ 32).
2019-02-24 04:41:42 -07:00
\fI\*(XT\fP supports more than one scheme for extending this range,
by changing the protocol encoding:
.IP "UTF-8 (1005)"
This enables UTF-8 encoding for \*(Cx and \*(Cy under
all tracking modes, expanding the maximum encodable position from 223 to 2015.
For positions less than 95, the resulting output is identical under both modes.
Under extended mouse mode, positions greater than 95
2019-02-24 04:41:42 -07:00
generate \*(``extra\*('' bytes which will confuse
applications which do not treat their input as a UTF-8 stream.
Likewise, \*(Cb will be UTF-8 encoded,
to reduce confusion with wheel mouse events.
.IP
Under normal mouse mode, positions outside (160,94) result in
byte pairs which can be interpreted as a single UTF-8 character;
applications
which do treat their input as UTF-8 will almost certainly be confused
unless extended mouse mode is active.
.IP
This scheme has the drawback that the encoded coordinates will not
pass through \fIluit\fP unchanged, e.g., for locales using non-UTF-8 encoding.
.IP "SGR (1006)"
The normal mouse response is altered to use \*(Cs\*<
followed by semicolon-separated
encoded button value,
the \*(Cx and \*(Cy ordinates and a final character which
is \*M for button press
and \*m for button release.
2013-03-09 07:45:38 -07:00
.RS
.bP
The encoded button value in this case does not add 32 since
that was useful only in the X10 scheme for ensuring that the
byte containing the button value is a printable code.
2013-03-09 07:45:38 -07:00
.bP
The modifiers are encoded in the same way.
2013-03-09 07:45:38 -07:00
.bP
A different final character is used for button release
to resolve the X10 ambiguity regarding which button was released.
2013-03-09 07:45:38 -07:00
.RE
.IP
The highlight tracking responses are also modified to an SGR-like format,
using the same SGR-style scheme and button-encodings.
.IP "URXVT (1015)"
The normal mouse response is altered to use \*(Cs
followed by semicolon-separated
encoded button value,
the \*(Cx and \*(Cy ordinates and final character \*M.
.IP
This uses the same button encoding as X10, but printing it as
a decimal integer rather than as a single byte.
.IP
However, \*(Cs\*M can be mistaken for DL (delete lines),
while the highlight tracking \*(Cs\*T can be mistaken for SD (scroll down),
and the Window manipulation controls.
For these reasons, the 1015 control is not recommended;
it is not an improvement over 1005.

.Sh "Further reading"
.Ss "Technical manuals"
.LP
Manuals for \fIhardware\fP terminals are more readily available than
similarly-detailed documentation for terminal \fIemulators\fP
such as \fIaixterm\fP, \fIshelltool\fP, \fIdtterm\fP.
.LP
However long, the technical manuals have problems:
.bP
DEC's manuals did not provide a comprehensive comparison of the features
in different model.
.IP
Peter Sichel's \fIHost Interface Functions Checklist\fP
spreadsheet is useful for noting
which model introduced a given feature (although there are a few apparent
errors such as the \fBDECRQSS\fP feature cited for VT320
whereas the technical manual omits it).
.bP
Sometimes the manuals disagree.
For example, DEC's standard document (DEC STD 070) for terminals says
that \fBDECSCL\fP performs a \fIsoft\fP reset (DECSTR),
while the VT420 manual says it does a \fIhard\fP reset (RIS).
.bP
Sometimes the manuals are simply incorrect.
For example, testing a DEC VT420 in 1996 showed that the documented
code for a valid or invalid response to \fBDECRQSS\fP was reversed.
.IP
The VT420 test results were incorporated into \fIvttest\fP program.
At the time, DEC STD 070 was not available,
but it also agrees with \fIvttest\fP.
Later, documentation for the DEC VT525 was shown to have the same flaw.
.bP
Not all details are clear even in DEC STD 070
(which is more than twice the length of the
VT520 programmer's reference manual,
and almost three times longer than the VT420 reference manual).
However, as an internal standards document,
DEC STD 070 is more likely to describe the actual behavior of DEC's terminals
than the more polished user's guides.
.LP
That said, here are technical manuals
which have been used in developing \fI\*(xt\fP.
Not all were available initially.
In August 1996 for instance, the technical references were
limited to
EK-VT220-HR-002 and
EK-VT420-UG.002.
Shortly after,
Richard Shuford sent a copy of
EK-VT3XX-TP-001.
Still later (beginning in 2003), Paul Williams' vt100.net site
provided
EK-VT102-UG-003,
EK-VT220-RM-002,
EK-VT420-RM-002,
EK-VT520-RM A01,
EK-VT100-TM-003, and
EK-VT102-UG-003.
The remaining documents were found on the bitsavers site.

.Ss "Miscellaneous"
.LP
A few hardware terminals survived into the 1990s only as terminal emulators.
Documentation for these and other terminal emulators
which have influenced \fI\*(xt\fP
are generally available only in
less-accessible and less-detailed manual pages.
.bP
\fI\*(XT\fP supports control sequences for manipulating its \fIwindow\fP
which were implemented by Sun's \fIshelltool\fP program.
This was part of SunView (SunOS 3.0, 1986).
The change-notes for \fI\*(xt\fP's \fIresize\fP program in X10.4 (1986)
mention its use of these \*(``Sun tty emulation escape sequences\*(''
for resizing the window.
The X10.4 \fI\*(xt\fP program recognized these sequences for resizing
the terminal, except for the iconfig/deiconfy pair.
SunView also introduced the \fBSIGWINCH\fP signal,
used by the X10.4 \fI\*(xt\fP and mentioned in its \fICHANGES\fP file:
.iP
.RS
The window size is passed to the operating system via TIOCSWINSZ (4.3) or
TIOCSSIZE (sun).
A SIGWINCH signal is sent if the vtXXX window is resized.
.RE
.IP
While support for the Sun control-sequences remained in \fIresize\fP,
the next release of \fI\*(xt\fP (X11R1 in 1987)
omitted the code for interpreting them.
.IP
Later, the SunView program was adapted for
the \fIOPEN LOOK\fP environment introduced 1988-1990.
.IP
Still later, in 1995, \fIOPEN LOOK\fP was abandoned in favor of \fICDE\fP.
The \fICDE\fP terminal emulator \fIdtterm\fP implemented those controls,
with a couple of additions.
.IP
Starting in July 1996,
\fI\*(xt\fP re-implemented those control sequences
(based on the \fIdtterm\fP manual pages)
and further extended the group of window controls.
.IP
There were two sets of controls
(\*(Cs\*(Ps[\*s\*;\*(Pm\*s\*;\*(Pm]\*t,
and \*(Os\*(Ps\fItext\fP\*(ST) implemented
by \fIshelltool\fP, documented in appendix E of both
\fIPHIGS Programming Manual\fP (1992), and the unpublished
\fIX Window System User's Guide (OPEN LOOK Edition)\fP (1995).
The \fICDE\fP program kept those,
and added a few new ones.

.br
Besides the Sun-derived OSC controls for setting window title and icon label,
\fIdtterm\fP also supported the \fI\*(xt\fP controls for the same feature.
.IP
The \fICDE\fP source was unavailable for inspection until 2012,
so that clarification of the details of the window operations
relied upon \fIvttest\fP.
.bP
The control sequences for saving/restoring the cursor and
for saving/restoring \*(``DEC Private Mode Values\*('' may appear to be
related (since the \*(``save\*('' controls both end with \*(cs),
but that is coincidental.
The latter was introduced in X10.4:
.iP
.RS
.ft C
.na
.hy 0
Most Dec Private mode settings can be save away internally using \\E[?ns,
where n is the same number to set or reset the Dec Private mode. The
mode can be restored using \\E[?nr. This can be used in termcap for vi, for
example, to turn off saving of lines, but restore whatever the original
state was on exit.
.hy

.ft R
.RE
.IP
while the SCOSC/SCORC pair was added in 1995 by XFree86
(and documented long afterwards).
.bP
The \fIaixterm\fP manual page gives the format of the control sequence
for foreground and background colors 8-15,
but does not specify what those colors are.
That is implied by the description's mention of \fIHFT\fP:
.iP
.RS
.na
.hy 0
.ft C
The aixterm command provides a standard terminal type for programs that
do not interact directly with Enhanced X-Windows.
This command provides
an emulation for a VT102 terminal or a high function terminal (HFT).
The VT102 mode is activated by the -v flag.
.ft R
.ad
.RE
.hy
.IP
Unlike \fI\*(xt\fP, there are no resource names for the 16 colors,
leaving the reader to assume that the mapping is hard-coded.
The control sequences for colors 8-15 are not specified by ECMA-48,
but rather (as done in other instances by \fI\*(xt\fP) chosen to
not conflict with current or future standards.
