NAME
mxterm - terminal emulator for X
SYNOPSIS
mxterm
[-toolkitoption ...] [-option ...]
DESCRIPTION
The mxterm program is a terminal emulator for the X Window System.
It provides DEC VT102 and Tektronix 4014
compatible terminals for programs that can't
use the window system directly. If the underlying operating system supports
terminal resizing capabilities (for example, the SIGWINCH signal in systems
derived from 4.3bsd), mxterm will use the facilities to notify programs
running in the window whenever it is resized.
The VT102 and Tektronix 4014 terminals each have their own window so that you
can edit text in one and look at graphics in the other at the same time.
To maintain the correct aspect ratio (height/width), Tektronix graphics will
be restricted to the largest box with a 4014's aspect ratio that will fit in
the window. This box is located in the upper left area of the window.
Although both windows may be displayed at the same time, one of them is
considered the ``active'' window for receiving keyboard input and terminal
output. This is the window that contains the text cursor.
The active window can be chosen through escape sequences,
the ``VT Options'' menu in the VT102 window, and the ``Tek Options''
menu in the 4014 window.
EMULATIONS
The VT102 emulation is fairly complete, but does not support the blinking
character attribute nor the double-wide and double-size character sets.
Termcap(5)
entries that work with
mxterm
include ``mxterm,'' ``vt102,'' ``vt100'' and ``ansi,'' and
mxterm
automatically searches the termcap file in this order for these entries and then
sets the ``TERM'' and the ``TERMCAP'' environment variables.
Many of the special
mxterm
features (like logging) may be modified under program control
through a set of escape sequences different from the standard VT102 escape
sequences.
(See the
Xterm Control Sequences
document.)
The Tektronix 4014 emulation is also fairly good.
Four different font sizes and five different lines types are supported.
The Tektronix text and graphics commands are recorded internally by
mxterm
and may be written to a file by sending the COPY escape sequence (or through
the
Tektronix
menu; see below).
The name of the file will be
``COPYyy-MM-dd.hh:mm:ss'', where
yy,
MM,
dd,
hh,
mm
and
ss
are the year, month, day, hour, minute and second when the COPY was performed
(the file is created in the directory
mxterm
is started in, or the home directory for a login
mxterm).
OTHER FEATURES
Xterm
automatically highlights the text cursor when the
pointer enters the window (selected) and unhighlights it when the pointer
leaves the window (unselected).
If the window is the focus window, then the text cursor is
highlighted no matter where the pointer is.
In VT102 mode, there are escape sequences to activate and deactivate
an alternate screen buffer, which is the same size as the display area
of the window.
When activated, the current screen is saved and replaced with the alternate
screen.
Saving of lines scrolled off the top of the window is disabled until the
normal screen is restored.
The
termcap(5)
entry for
mxterm
allows the visual editor
vi(1)
to switch to the alternate screen for editing and to restore the screen
on exit.
In either VT102 or Tektronix mode, there are escape sequences to change the
name of the windows and to specify a new log file name.
See Xterm Control Sequences for details.
Enabling the escape sequence to change the
log file name is a compile-time option;
by default this escape sequence is ignored for security reasons.
OPTIONS
The mxterm terminal emulator
accepts all of the standard X Toolkit command line options as well as
the following (if the option begins with a
`+'
instead of a
`-',
the option is restored to its default value):
- -help
-
This causes mxterm to print out a verbose message describing its options.
- -132
-
Normally, the VT102 DECCOLM escape sequence that switches between 80 and
132 column mode is ignored.
This option causes the DECCOLM escape sequence to be recognized, and the
mxterm
window will resize appropriately.
- -ah
-
This option indicates that
mxterm
should always highlight the text cursor. By default,
mxterm
will display a hollow text cursor whenever the focus is lost or the
pointer leaves the window.
- +ah
-
This option indicates that
mxterm
should do text cursor highlighting based on focus.
- -b number
-
This option specifies the size of the inner border (the distance between
the outer edge of the characters and the window border) in pixels. The
default is 2.
- -cb
-
Set the vt100 resource cutToBeginningOfLine to FALSE.
- +cb
-
Set the vt100 resource cutToBeginningOfLine to TRUE.
- -cc characterclassrange:value[,...]
-
This sets classes indicated by the given ranges for using in selecting by
words. See the section specifying character classes.
- -cn
-
This option indicates that newlines should not be cut in line-mode
selections.
- +cn
-
This option indicates that newlines should be cut in line-mode selections.
- -cr color
-
This option specifies the color to use for text cursor. The default is to
use the same foreground color that is used for text.
- -cu
-
This option indicates that mxterm should work around a bug in the
curses(3x)
cursor motion package that causes the
more(1)
program to display lines that are exactly the width of the window and
are followed by a line beginning with a tab to be displayed incorrectly
(the leading tabs are not displayed).
- +cu
-
This option indicates that that mxterm should not work around the
curses(3x)
bug mentioned above.
- -e program [arguments ...]
-
This option specifies the program (and its command line arguments) to be
run in the mxterm window. It also sets the window title and icon
name to be the basename of the program being executed if neither -T
nor -n are given on the command line. This must be the last
option on the command line.
- -fb font
-
This option specifies a font to be used when displaying bold text.
This font must be the same height and width as the normal font.
If only one of the normal or bold fonts is specified, it will be used as the
normal font and the bold font will be produced by overstriking this font.
The default is to do overstriking of the normal font.
- -im
-
Turn on the useInsertMode resource.
- +im
-
Turn off the useInsertMode resource.
- -j
-
This option indicates that mxterm should do jump scrolling. Normally,
text is scrolled one line at a time; this option allows mxterm to move
multiple lines at a time so that it doesn't fall as far behind. Its use is
strongly recommended since it make mxterm much faster when scanning
through large amounts of text. The VT100 escape sequences for enabling and
disabling smooth scroll as well as the ``VT Options''
menu can be used to turn this
feature on or off.
- +j
-
This option indicates that mxterm should not do jump scrolling.
- -l
-
This option indicates that mxterm should send all terminal output to
a log file as well as to the screen. This option can be enabled or disabled
using the ``VT Options'' menu.
- +l
-
This option indicates that mxterm should not do logging.
- -lf filename
-
This option specifies the name of the file to which the output log described
above is written. If file begins with a pipe symbol (|), the rest of
the string is assumed to be a command to be used as the endpoint of a pipe.
The ability to log to a pipe is a compile-time option which is
disabled by default for security reasons.
The default filename is ``XtermLog.XXXXX'' (where XXXXX
is the process id of mxterm) and is created in the directory from which
mxterm was started (or the user's home directory in the case of a
login window).
- -ls
-
This option indicates that the shell that is started in the mxterm window
be a login shell (i.e. the first character of argv[0] will be a dash,
indicating to the shell that it should read the user's .login or .profile).
- +ls
-
This option indicates that the shell that is started should not be a login
shell (i.e. it will be a normal ``subshell'').
- -mb
-
This option indicates that mxterm should ring a margin bell when
the user types near the right end of a line. This option can be turned on
and off from the ``VT Options'' menu.
- +mb
-
This option indicates that margin bell should not be rung.
- -mc milliseconds
-
This option specifies the maximum time between multi-click selections.
- -ms color
-
This option specifies the color to be used for the pointer cursor. The default
is to use the foreground color.
- -nb number
-
This option specifies the number of characters from the right end of a line
at which the margin bell, if enabled, will ring. The default is 10.
- -rw
-
This option indicates that reverse-wraparound should be allowed. This allows
the cursor to back up from the leftmost column of one line to the rightmost
column of the previous line. This is very useful for editing long shell
command lines and is encouraged. This option can be turned on and off from
the ``VT Options'' menu.
- +rw
-
This option indicates that reverse-wraparound should not be allowed.
- -aw
-
This option indicates that auto-wraparound should be allowed. This
allows the cursor to automatically wrap to the beginning of the next
line when when it is at the rightmost position of a line and text is
output.
- +aw
-
This option indicates that auto-wraparound should not be allowed.
- -s
-
This option indicates that mxterm may scroll asynchronously, meaning that
the screen does not have to be kept completely up to date while scrolling.
This allows mxterm to run faster when network latencies are very high
and is typically useful when running across a very large internet or many
gateways.
- +s
-
This option indicates that mxterm should scroll synchronously.
- -sb
-
This option indicates that some number of lines that are scrolled off the top
of the window should be saved and that a scrollbar should be displayed so that
those lines can be viewed. This option may be turned on and off from the
``VT Options'' menu.
- +sb
-
This option indicates that a scrollbar should not be displayed.
- -sf
-
This option indicates that Sun Function Key escape codes should be generated
for function keys.
- +sf
-
This option indicates that the standard escape codes should be generated for
function keys.
- -si
-
This option indicates that output to a window should not automatically
reposition the screen to the bottom of the scrolling region.
This option can be turned on and off from the ``VT Options'' menu.
- +si
-
This option indicates that output to a window should cause it to
scroll to the bottom.
- -sk
-
This option indicates that pressing a key while
using the scrollbar to review previous lines of text should
cause the window to be repositioned automatically in the normal position at the
bottom of the scroll region.
- +sk
-
This option indicates that pressing a key while using the scrollbar
should not cause the window to be repositioned.
- -sl number
-
This option specifies the number of lines to save that have been scrolled
off the top of the screen. The default is 64.
- -t
-
This option indicates that mxterm should start in Tektronix mode, rather
than in VT102 mode. Switching between the two windows is done using the
``Options'' menus.
- +t
-
This option indicates that mxterm should start in VT102 mode.
- -tm string
-
This option specifies a series of terminal setting keywords followed by the
characters that should be bound to those functions, similar to the stty
program. Allowable keywords include: intr, quit, erase, kill, eof,
eol, swtch, start, stop, brk, susp, dsusp, rprnt, flush, weras, and lnext.
Control characters may be specified as ^char (e.g. ^c or ^u) and ^? may be
used to indicate delete.
- -tn name
-
This option specifies the name of the terminal type to be set in the TERM
environment variable. This terminal type must exist in the termcap(5)
database and should have li# and co# entries.
- -ut
-
This option indicates that mxterm shouldn't write a record into the
the system log file /etc/utmp.
- +ut
-
This option indicates that mxterm should write a record into the system
log file /etc/utmp.
- -vb
-
This option indicates that a visual bell is preferred over an audible one.
Instead of ringing the terminal bell whenever a Control-G is received, the
window will be flashed.
- +vb
-
This option indicates that a visual bell should not be used.
- -wf
-
This option indicates that mxterm should wait for the window to be mapped
the first time before starting the subprocess so that the initial terminal
size settings and environment variables are correct. It is the application's
responsibility to catch subsequent terminal size changes.
- +wf
-
This option indicates that mxterm show not wait before starting the
subprocess.
- -C
-
This option indicates that this window should receive console output. This
is not supported on all systems. To obtain console output, you must be the
owner of the console device, and you must have read and write permission
for it. If you are running X under xdm on the console screen you may
need to have the session startup and reset programs explicitly change the
ownership of the console device in order to get this option to work.
- -Sccn
-
This option specifies the last two letters of the name of a pseudoterminal
to use in slave mode, plus the number of the inherited file descriptor.
The option is parsed ``%c%c%d''.
This allows mxterm to be used as an input and
output channel for an existing program and is sometimes used in specialized
applications.
The following command line arguments are provided for compatibility with
older versions. They may not be supported in the next release as the X
Toolkit provides standard options that accomplish the same task.
- %geom
-
This option specifies the preferred size and position of the Tektronix window.
It is shorthand for specifying the ``*tekGeometry'' resource.
- #geom
-
This option specifies the preferred position of the icon window.
It is shorthand for specifying the ``*iconGeometry'' resource.
- -T string
-
This option specifies the title for mxterm's windows.
It is equivalent to -title.
- -n string
-
This option specifies the icon name for mxterm's windows.
It is shorthand for specifying the ``*iconName'' resource.
Note that this is not the same as the toolkit option -name (see below).
The default icon name is the application name.
- -r
-
This option indicates that reverse video should be simulated by swapping
the foreground and background colors. It is equivalent to
-rv.
- -w number
-
This option specifies the width in pixels of the border surrounding the window.
It is equivalent to -borderwidth or -bw.
The following standard X Toolkit command line arguments are commonly used
with mxterm:
- -bg color
-
This option specifies the color to use for the background of the window.
The default is ``white.''
- -bd color
-
This option specifies the color to use for the border of the window.
The default is ``black.''
- -bw number
-
This option specifies the width in pixels of the border surrounding the window.
- -fg color
-
This option specifies the color to use for displaying text. The default is
``black.''
- -fn font
-
This option specifies the font to be used for displaying normal text. The
default is fixed.
- -name name
-
This option specifies the application name under which resources are to be
obtained, rather than the default executable file name.
Name should not contain ``.'' or ``*'' characters.
- -title string
-
This option specifies the window title string, which may be displayed by
window managers if the user so chooses. The default title is the command
line specified after the -e option, if any, otherwise the application
name.
- -rv
-
This option indicates that reverse video should be simulated by swapping
the foreground and background colors.
- -geometry geometry
-
This option specifies the preferred size and position of the VT102 window;
see X(1).
- -display display
-
This option specifies the X server to contact; see X(1).
- -xrm resourcestring
-
This option specifies a resource string to be used. This is especially
useful for setting resources that do not have separate command line options.
- -iconic
-
This option indicates that mxterm should ask the window manager to
start it as an icon rather than as the normal window.
RESOURCES
The program understands all of the core X Toolkit resource names and
classes as well as:
- iconGeometry (class IconGeometry)
-
Specifies the preferred size and position of the application when iconified.
It is not necessarily obeyed by all window managers.

-
Specifies a string containing terminal setting keywords and the characters
to which they may be bound. Allowable keywords include: intr, quit,
erase, kill, eof, eol, swtch, start, stop, brk, susp, dsusp, rprnt, flush,
weras, and lnext. Control characters may be specified as ^char (e.g. ^c or ^u)
and ^? may be used to indicate Delete. This is very useful for overriding
the default terminal settings without having to do an stty every time
an mxterm is started.
- useInsertMode (class UseInsertMode)
-
Force use of insert mode by adding appropriate entries to the TERMCAP
environment variable. This is useful if the system termcap is broken.
The default is ``false.''
- utmpInhibit (class UtmpInhibit)
-
Specifies whether or not mxterm should try to record the user's terminal
in /etc/utmp.
- sunFunctionKeys (class SunFunctionKeys)
-
Specifies whether or not Sun Function Key escape codes should be generated for
function keys instead of standard escape sequences.
- waitForMap (class WaitForMap)
-
Specifies whether or not mxterm should wait for the initial window map
before starting the subprocess. The default is ``false.''
The following resources are specified as part of the vt100 widget (class
VT100):
- allowSendEvents (class AllowSendEvents)
-
Specifies whether or not synthetic key and button events (generated using
the X protocol SendEvent request) should be interpreted or discarded.
The default is ``false'' meaning they are discarded. Note that allowing
such events creates a very large security hole.
- alwaysHighlight (class AlwaysHighlight)
-
Specifies whether or not mxterm should always display a highlighted
text cursor. By default, a hollow text cursor is displayed whenever the
pointer moves out of the window or the window loses the input focus.

-
Specifies whether or not auto-wraparound should be enabled. The
default is ``true.''
- bellSuppressTime (class BellSuppressTime)
-
Number of milliseconds after a bell command is sent during which additional
bells will be suppressed. Default is 200. If set non-zero,
additional bells
will also be suppressed until the server reports that processing of
the first bell has been completed; this feature is most useful with
the visible bell.
- boldFont (class BoldFont)
-
Specifies the name of the bold font to use instead of overstriking.

-
If false, triple clicking to select a line selects only from the
current word forward.
If true, the entire line is selected.
The default is ``true.''

-
Specifies whether or not the last column bug in
curses(3x)
should be worked around.
The default is ``false.''
- background (class Background)
-
Specifies the color to use for the background of the window. The default is
``white.''
- foreground (class Foreground)
-
Specifies the color to use for displaying text in the window. Setting the
class name instead of the instance name is an easy way to have everything
that would normally appear in the text color change color. The default
is ``black.''
- cursorColor (class Foreground)
-
Specifies the color to use for the text cursor. The default is ``black.''
- eightBitInput (class EightBitInput)

Specifies the name of the file to which a terminal session is logged. The
default is ``XtermLog.XXXXX'' (where XXXXX
is the process id of mxterm).
- logging (class Logging)
-
Specifies whether or not a terminal session should be logged. The default is
``false.''
- logInhibit (class LogInhibit)
-
Specifies whether or not terminal session logging should be inhibited. The

- resizeGravity (class ResizeGravity)
-
Affects the behavior when the window is resized to be taller or
shorter. NorthWest
specifies that the top line of text on the screen stay fixed. If the window
is made shorter, lines are dropped from the bottom; if the window is
made taller, blank lines are added at the bottom. This is compatible
with the behavior in R4. SouthWest (the default) specifies that
the bottom line of text on the screen stay fixed. If the window is
made taller, additional saved lines will be scrolled down onto the
screen; if the window is made shorter, lines will be scrolled off the
top of the screen, and the top saved lines will be dropped.
- reverseVideo (class ReverseVideo)

-
Specifies whether or not mxterm should start up in Tektronix mode.
The default is ``false.''
- titeInhibit (class TiteInhibit)
-
Specifies whether or not mxterm should remove remove ti and te
termcap entries (used to switch between alternate screens on startup of many
screen-oriented programs) from the TERMCAP string. If set,
mxterm also ignores the escape sequence to switch to the
alternate screen.

POINTER USAGE
Once the VT102 window is created,
mxterm
allows you to select text and copy it within the same or other windows.
The selection functions are invoked when the pointer buttons are used with no
modifiers, and when they are used with the ``shift'' key.
The assignment of the functions described below to keys and buttons may
be changed through the resource database; see ACTIONS below.
Pointer button one (usually left) is used to save text into the cut buffer.
Move the cursor to beginning of the text,
and then hold the button down while moving the cursor to the end of the region
and releasing the button.
The selected text is highlighted and is saved in the global cut buffer
and made the PRIMARY selection when
the button is released. Double-clicking selects by words. Triple-clicking
selects by lines. Quadruple-clicking goes back to characters, etc.
Multiple-click is determined by the time from button up to
button down, so you can change the selection unit in the middle of a selection.
If the key/button bindings specify that an X selection is to be made,
mxterm will leave the selected text highlighted for as long as it
is the selection owner.
Pointer button two (usually middle) `types' (pastes) the text from
the PRIMARY selection, if any, otherwise from
the cut buffer,
inserting it as keyboard input.
Pointer button three (usually right) extends the current selection.
(Without loss of generality,
you can swap ``right'' and ``left'' everywhere in the rest of this
paragraph.) If pressed while closer to
the right edge of the selection than the left, it extends/contracts the
right edge of the selection. If you contract the selection past
the left edge of the selection,
mxterm
assumes you really meant the left edge, restores the original selection, then
extends/contracts the left edge of the selection. Extension starts in the
selection unit mode
that the last selection or extension was performed in; you can multiple-click
to cycle through them.
By cutting and pasting pieces of text without trailing new lines,
you can take text from several places in different windows and form a command
to the shell, for example, or take output from a program and insert it into
your favorite editor.
Since the cut buffer is globally shared among different applications,
you should regard it as a `file' whose contents you know.
The terminal emulator and other text programs should be treating it as if it
were a text file, i.e., the text is delimited by new lines.
The scroll region displays the position and amount of text currently showing
in the window (highlighted) relative to the amount of text actually saved.
As more text is saved (up to the maximum), the size of the highlighted area
decreases.
Clicking button one with the pointer in the scroll region moves the
adjacent line to the top of the display window.
Clicking button three moves the top line of the display window down to the
pointer position.
Clicking button two moves the display to a position in the saved text
that corresponds to the pointer's position in the scrollbar.
Unlike the VT102 window, the Tektronix window dows not allow the copying of
text.
It does allow Tektronix GIN mode, and in this mode
the cursor will change from an arrow to a cross.
Pressing any key will send that key and the current coordinate of the
cross cursor.
Pressing button one, two, or three will return the letters `l', `m', and
`r', respectively.
If the `shift' key is pressed when a pointer button is pressed, the corresponding
upper case letter is sent.
To distinguish a pointer button from a key, the high bit of the character is
set (but this is bit is normally stripped unless the terminal mode is RAW;
see
tty(4)
for details).
MENUS
Xterm
has four menus, named
mainMenu,
vtMenu,
fontMenu,
and
tekMenu.
Each menu pops up under the correct combinations of key and button presses.
Most menus are divided into two section, separated by a horizontal line.
The top portion contains various modes that can be altered.
A check mark appears next to a mode that is currently active.
Selecting one of these modes toggles its state.
The bottom portion of the menu are command entries; selecting one of these
performs the indicated function.
The
mxterm
menu pops up when the ``control'' key and pointer button one are
pressed in a window.
The mainMenu contains items that apply to both the VT102 and Tektronix
windows.
The
Secure Keyboard
mode is be used when typing in passwords or other sensitive data in an
unsecure environment;
see SECURITY below.
Notable entries in the command section of the menu are the
Continue,
Suspend,
Interrupt,
Hangup,
Terminate
and
Kill
which sends the SIGCONT, SIGTSTP, SIGINT, SIGHUP, SIGTERM and
SIGKILL signals, respectively, to the process group of the process running
under
mxterm
(usually the shell).
The
Continue
function is especially useful if the user has accidentally typed CTRL-Z,
suspending the process.
The
vtMenu
sets various modes in the VT102 emulation, and is popped up when the
``control'' key and pointer button two are pressed in the VT102 window.
In the command section of this menu, the soft reset entry will reset
scroll regions.
This can be convenient when some program has left the scroll regions
set incorrectly (often a problem when using VMS or TOPS-20).
The full reset entry will clear the screen, reset tabs to every
eight columns, and reset the terminal modes (such as wrap and smooth scroll)
to their initial states just after
mxterm
has finished processing the command line options.
The fontMenu sets the font used in the VT102 window.
In addition to the default font and a number of alternatives that are
set with resources, the menu offers the font last specified by the Set
Font escape sequence (see the document Xterm Control Sequences)
and the current selection as a font name (if the PRIMARY selection is owned).
The
tekMenu
sets various modes in the Tektronix emulation, and is popped up when the
``control'' key and pointer button two are pressed in the Tektronix window.
The current font size is checked in the modes section of the menu.
The
PAGE
entry in the command section clears the Tektronix window.
SECURITY
X environments differ in their security consciousness. MIT servers, run
under xdm, are capable of using a ``magic cookie'' authorization
scheme that can provide a reasonable level of security for many people.
If your server is only using a host-based mechanism to control access to
the server (see xhost(1)), then if you enable access for a host and
other users are also permitted to run clients on that same host, there is
every possibility that someone can run an application that will use the
basic services of the X protocol to snoop on your activities, potentially
capturing a transcript of everything you type at the keyboard.
This is of particular concern when you want to type in a password or other
sensitive data. The best solution to this problem is to use a better
authorization mechanism that host-based control, but a simple
mechanism exists for protecting keyboard input in mxterm.
The mxterm menu (see MENUS above) contains a Secure Keyboard
entry which, when enabled, ensures that all keyboard input is directed
only to mxterm (using the GrabKeyboard protocol request).
When an application prompts you for a password
(or other sensitive data), you can enable Secure Keyboard using the
menu, type in the data, and then disable Secure Keyboard using
the menu again. Only one X client at a time can secure the keyboard,
so when you attempt to enable Secure Keyboard it may fail. In
this case, the bell will sound. If the Secure Keyboard succeeds,
the foreground and background colors will be exchanged (as if you
selected the Reverse Video entry in the Modes menu);
they will be exchanged again when you exit secure mode. If the colors
do not switch, then
you should be very suspicious that you are being spoofed. If
the application you are running displays a prompt before asking for
the password, it is safest to enter secure mode before the
prompt gets displayed, and to make sure that the prompt gets displayed
correctly (in the new colors), to minimize the probability of
spoofing. You can also bring up the menu again and make sure that a check
mark appears next to the entry.
Secure Keyboard mode will be disabled automatically if your mxterm
window becomes iconified (or otherwise unmapped), or if you start up
a reparenting window manager (that places a title bar or other decoration
around the window) while in Secure Keyboard mode. (This is a
feature of the X protocol not easily overcome.) When this happens,
the foreground and background colors will be switched back and the bell
will sound in warning.
CHARACTER CLASSES
Clicking the middle mouse button twice in rapid succession will cause all
characters of the same class (e.g. letters, white space, punctuation) to be
selected. Since different people have different preferences for what should
be selected (for example, should filenames be selected as a whole or only
the separate subnames), the default mapping can be overridden through the use
of the charClass (class CharClass) resource.
This resource is simply a list of range:value pairs where the
range is either a single number or low-high in the range of 0
to 127, corresponding to the ASCII code for the character or characters to be
set. The value is arbitrary, although the default table uses the
character number of the first character occurring in the set.
The default table is
static int charClass[128] = {
/* NUL SOH STX ETX EOT ENQ ACK BEL */
32, 1, 1, 1, 1, 1, 1, 1,
/* BS HT NL VT NP CR SO SI */
1, 32, 1, 1, 1, 1, 1, 1,
/* DLE DC1 DC2 DC3 DC4 NAK SYN ETB */
1, 1, 1, 1, 1, 1, 1, 1,
/* CAN EM SUB ESC FS GS RS US */
1, 1, 1, 1, 1, 1, 1, 1,
/* SP ! " # $ % & ' */
32, 33, 34, 35, 36, 37, 38, 39,
/* ( ) * + , - . / */
40, 41, 42, 43, 44, 45, 46, 47,
/* 0 1 2 3 4 5 6 7 */
48, 48, 48, 48, 48, 48, 48, 48,
/* 8 9 : ; < = > ? */
48, 48, 58, 59, 60, 61, 62, 63,
/* @ A B C D E F G */
64, 48, 48, 48, 48, 48, 48, 48,
/* H I J K L M N O */
48, 48, 48, 48, 48, 48, 48, 48,
/* P Q R S T U V W */
48, 48, 48, 48, 48, 48, 48, 48,
/* X Y Z [ \ ] ^ _ */
48, 48, 48, 91, 92, 93, 94, 48,
/* ` a b c d e f g */
96, 48, 48, 48, 48, 48, 48, 48,
/* h i j k l m n o */
48, 48, 48, 48, 48, 48, 48, 48,
/* p q r s t u v w */
48, 48, 48, 48, 48, 48, 48, 48,
/* x y z { | } ~ DEL */
48, 48, 48, 123, 124, 125, 126, 1};
For example, the string ``33:48,37:48,45-47:48,64:48'' indicates that the
exclamation mark, percent sign, dash, period, slash, and ampersand characters
should be treated the same way as characters and numbers. This is very useful
for cutting and pasting electronic mailing addresses and filenames.
ACTIONS
It is possible to rebind keys (or sequences of keys) to arbitrary strings
for input, by changing the translations for the vt100 or tek4014 widgets.
Changing the translations for events other than key and button events
is not expected, and will cause unpredictable behavior. The following
actions are provided for using within the vt100 or tek4014
translations resources:
- bell([percent])
-
This action rings the keyboard bell at the specified percentage
above or below the base volume.
- ignore()
-
This action ignores the event but checks for special pointer position
escape sequences.
- insert()
-
This action inserts the character or string associated with
the key that was pressed.
- insert-seven-bit()
-
This action is a synonym for insert()
- insert-eight-bit()
-
This action inserts an eight-bit (Meta) version of the character or string
associated with the key that was pressed.
The exact action depends on the value of the eightBitInput resource.
- insert-selection(sourcename [, ...])
-
This action inserts the string found in the selection or cutbuffer indicated
by sourcename. Sources are checked in the order given (case is
significant) until one is found. Commonly-used selections include:
PRIMARY, SECONDARY, and CLIPBOARD. Cut buffers are
typically named CUT_BUFFER0 through CUT_BUFFER7.
- keymap(name)
-
This action dynamically defines a new translation table whose resource
name is name with the suffix Keymap (case is significant).
The name None restores the original translation table.

should only be bound to Motion events.
- select-end(destname [, ...])
-
This action puts the currently selected text into all of the selections or
cutbuffers specified by destname.
- select-cursor-start()
-
This action is similar to select-start except that it begins the
selection at the current text cursor position.

with select-cursor-start.
- set-vt-font(d/1/2/3/4/5/6/e/s [,normalfont [, boldfont]])
-
This action sets the font or fonts currently being used in the VT102 window.
The first argument is a single character that specifies the font to be
used: d or D indicate the default font (the font initially
used when
mxterm was started), 1 through 6 indicate the fonts
specified by the font1 through font6 resources, e or E
indicate the normal and bold fonts that have been set through escape codes
(or specified as the second and third action arguments, respectively), and
s or S indicate the font selection (as made by programs such as
xfontsel(1)) indicated by the second action argument.
- start-extend()
-
This action is similar to select-start except that the
selection is extended to the current pointer location.

-
This action is similar to select-extend except that the
selection is extended to the current text cursor position.
- string(string)
-
This action inserts the specified text string as if it had been typed.
Quotation is necessary if the string contains whitespace or
non-alphanumeric characters. If the string argument begins with the
characters ``0x'', it is interpreted
as a hex character constant.
- scroll-back(count [,units])

ENVIRONMENT
Xterm
sets the environment variables ``TERM'' and ``TERMCAP'' properly for the
size window you have created.
It also uses and sets the environment
variable ``DISPLAY'' to specify which bit map display terminal to use.
The environment variable ``WINDOWID'' is set to the X window id number
of the
mxterm
window.

BUGS
Large pastes do not work on some systems. This is not a bug in
mxterm; it is a bug in the pseudo terminal driver of those
systems. mxterm feeds large pastes to the pty only as fast as the pty
will accept data, but some pty drivers do not return enough information
to know if the write has succeeded.
Many of the options are not resettable after

The Tek widget does not support key/button re-binding.
Only fixed-width, character-cell fonts are supported.
This program still needs to be rewritten. It should be split into very

There needs to be a dialog box to allow entry of log file name
and the COPY file name.
