SYNOPSISdxterm [options]
OPTIONS
Specifies a value for a dxterm resource that overrides a default set‐
ting. The string has the form resource:value. You can specify this
option multiple times to change multiple resources. See the X DEFAULTS
section in this reference page for a list of resources that can be
changed. You can specify both dxterm and shell resources as *resource.
Specifies the display screen on which dxterm displays its window. If
the display option is not specified, dxterm uses the display screen
specified by your DISPLAY environment variable. The display option has
the format hostname:number. The default is :0. For more information,
see X(1X). Performs the same function as the -d option. Specifies
that the named command, and any of its specified options, be executed
in the dxterm window when the window is first created. This option must
appear last on the dxterm command line. Specifies the width, length,
and location of the dxterm window, in columns, rows and pixels respec‐
tively. This option has the format [width][xlength][+x][+y]. Specifies
that dxterm create a login shell rather than a subshell. If this option
is present, a login record is written to the utmp and wtmp databases.
Specifies the setup file that provides parameters which control the
terminal's initial settings. This file must contain valid dxterm
resources. See the X DEFAULTS section below for a list of available
resources. Specifies the size of the dxterm window in columns (C) and
rows (R). Performs the same function as the -customization option.
DESCRIPTION
The dxterm command displays a window that provides VT320 terminal emu‐
lation and a standard terminal type for programs not directly aware of
the X Window System. The terminal emulator also supports the ReGIS and
Sixel graphics protocols.
Note
The dxterm terminal emulator does not support the following locales:
Unicode (.UTF-8) locales Latin-9 (.ISO8859-15) locales
To work around these restrictions, use the dtterm terminal emulator.
The dtterm terminal emulator is the default terminal emulator for the
Common Desktop Environment (CDE).
MENUS
The menu bar contains the following items: File Edit Commands Options
Print Help
File Menu
The File menu contains the following item: Shuts down the terminal emu‐
lator application: removes all its windows, stops the process running
the emulator, and ends any applications.
Edit Menu
The Edit menu contains the following items: Copies the text selected
from the dxterm window onto the clipboard. Pastes text selected from
the clipboard into the dxterm window, as if it had been typed. Selects
all displayed text.
Commands Menu
The Commands menu contains the following items: Prevents processes
other than the owner process from accessing the keyboard. Selecting
this option reverses the foreground and background colors. Erases data
recorded by dxterm from the top of the scrolling area. Clears the dis‐
play and positions the cursor at the first column and first line of the
display. Changes the size of the window to match the display so that
all characters in the display are visible. Clears the communication
buffers. Resets the emulator to the original settings. For example,
sets the keyboard action mode to unlocked and the keypad mode to
numeric.
Options Menu
The dxterm setup features are grouped into a number of related cate‐
gories. The Options menu lets you access the dialog box for each of
these categories, which correspond to those for VT320 Set-Up screens.
The Options menu contains the following items: Displays the Window
Options dialog box, which contains controls that affect the window fea‐
tures. Displays the Display Options dialog box, which contains con‐
trols that affect the appearance of the user's current window. Dis‐
plays the General Options dialog box, which contains controls for com‐
monly changed Customize features. Displays the Keyboard Options dialog
box, which contains controls for keyboard operating features. Allows
you to specify a 7-bit National Replacement Character Set (NRCS). Dis‐
plays the Graphics Options dialog box, which contains controls for
ReGIS and Sixel graphics. Displays the Printer Options dialog box,
which contains controls that affect printer features. Saves the cur‐
rent settings to the file ~/DXterm or ~/DXterm_locale, where locale is
the current locale (for example, en_US or ja_JP). The locale string is
appended to the resource file name unless the locale is C, begins with
en_US, or contains 8859-1. See the RESTRICTIONS section below for cau‐
tions on using this option. Restores the setup configuration from the
most recently read or written saved setup file. (This item corresponds
to NVR [nonvolatile RAM] recall on a VT320 terminal.) Saves the cur‐
rent settings in the file you specify. Opens a different saved setup
configuration. The standard DECwindows file selection dialog box
appears, showing a list of saved setup files in the current directory.
Selecting one of these files and clicking on OK (or double-clicking on
the file) reinitializes the terminal emulator with the configuration
stored in that file. Reinitializes the terminal emulator with the sys‐
tem default characteristics defined by your system.
Print Menu
The Print menu contains the following items: Prints the text in the
current window. Prints the selected information. Prints the informa‐
tion in the display and transcript as text. Prints the contents of the
display in Sixel format. Completes a print job depending on the print
destination. If queued to a printer, the job is submitted. If submit‐
ted to a dedicated printer port, the job is canceled. If written to a
file, the file is closed. This option is used with Auto Print mode or
Printer Controller mode. Stops the print request.
Help Menu
The Help menu contains the following items: Provides information about
an object in a window or a dialog box. To display context-sensitive
help, choose Context-Sensitive Help from the Help menu. The pointer
changes to a question mark. Move the question mark to a menu, a but‐

Displays an overview of DECterm along with help on how to perform vari‐
ous functions using DECterm. Displays information about how to use the
help system. Displays copyright and version information about DECterm.
Options Dialog Boxes
The Options dialog boxes represent the state of the terminal. At
application startup, the previously saved states for most terminal fea‐
tures are read from a saved set-up file (which corresponds to VT320
NVR). These feature settings remain constant until you explicitly
change them. You can change terminal operating features directly by
means of the Options dialog boxes. You can also change some of these
features indirectly by means of control functions from the host.
There are a few terminal features whose states are not stored in a
saved setup file. These features are restored to their factory default
values at application startup or when you reset the terminal (with
Reset Terminal or DECSTR).
Window Options Dialog Box
The Window Options dialog box lets you change the following window
attributes: Changes the terminal size to match the window size automat‐
ically whenever the window size changes. Changes the window size to
match the terminal size automatically whenever the terminal size
changes. Changes the terminal size to match the size known to the ter‐
minal driver whenever the size changes in the terminal driver, and vice
versa. Sets the number of rows and columns that are displayed. You can
select 24, 48, or 72 rows and 80 or 132 columns, or enter a custom size
in the numeric entry fields. Uses a normal (non-condensed) font for
all column widths. Uses a condensed font for all column widths. Uses
a normal (non-condensed) font for column widths of 80 characters or
less, and a condensed font otherwise. By default, dxterm uses an
18-pixel font. This default can be changed by selecting the Other
radio button and entering a font name in the text field next to this
radio button. By default, dxterm uses a 14-pixel font. This default
can be changed by selecting the Other radio button and entering a font
name in the text field next to this radio button. Displays a font that
meets the German Technical Supervision Association (TUV) requirements.
Changes the title displayed in the title bar. Changes the title dis‐
played in the icon box.
Display Options Dialog Box
The Display Options dialog box lets you change the following display
attributes: Saves lines that are scrolled off the top of the display.
When this option is enabled, any text that scrolls off the top of the
display is saved in the scrollback buffer. The default number of lines
saved is 100. To see the lines in this area, scroll the display using
the mouse in the vertical scrollbar. Or scroll by holding down the Ctrl
key and pressing either the up/down arrow keys or the Next Page or Pre‐
vious Page keys (Page Up and Page Down keys on PC-style keyboards).
Displays a vertical scroll bar along the right side of the dxterm win‐
dow. Displays a horizontal scroll bar along the bottom of the dxterm
window. Specifies that the window scrolls vertically so the cursor is
visible. Specifies that the window scrolls horizontally so the cursor
is visible. Specifies that when the cursor reaches the right margin,
new characters are displayed on the next line. If you do not automati‐
cally wrap text, when the cursor reaches the right margin, each new
character deletes the previous character. Specifies whether the cursor
is displayed. The default is to display the cursor. Specifies whether
the cursor blinks. The default is to have the cursor blink. Specifies
how many lines scroll at the same time. Increasing the Batch Scroll
count improves performance but makes it harder to read text while it is
scrolling. Specifies how many lines to save when they scroll off the
top of the display (that is, when the Record Lines Off Top item is
enabled). Sets dark text on a light background display. Sets light
text on a dark background display. Suppresses the status line at the
bottom of the window. Specifies that a host-writable status line
appears at the bottom of the window. Specifies that the text cursor is
a block that covers the character cell. Specifies that the text cursor
is an underline at the bottom of the character cell.
General Options Dialog Box
The General Options dialog box lets you change the following general
attributes: Turns on newline mode (NLM), which causes the Return key to
send a line feed as well as a carriage return. With newline mode, the
line feed character moves the cursor to the start of the line as well
as advancing it to the next line. Locks the user-defined keys so that
the host system cannot change these definitions. Stops the host from
changing your customized settings for the Auto Repeat key and the Fore‐
ground and Background display. Causes every character to be echoed to
the screen and sent to the host. Specifies that the arrow keys are set
to the characters labeled on the keycaps. The keys are not mapped to
any other functions. Specifies that the arrow keys are mapped to
application-specific functions. Specifies that the numeric keypad is
set to the characters labeled on the keycaps. Specifies that the
application keypad is set to function as user-defined keys. Specifies
that dxterm use the DIGITAL Multinational Character Set (DMCS). To use
this character set, set the Character Set mode menu item to 8-bit Char‐
acters. The default is 8-bit character mode. Specifies that dxterm
use the International Standards Organization (ISO) Character Set. To
use this character set, set the Character Set mode menu item to 8-bit
Characters. Specifies the character set mode to be 8 bits for use with
the ISO Latin-1 Character Set. The default is 8-bit character mode.
Specifies the character set mode to be 7 bits for use with the National
Replacement Character Sets. The default is 8-bit character mode.
Specifies that the terminal operates in VT300 mode and transmits 8-bit
control characters. Specifies that the terminal operates in VT300 mode
and transmits 7-bit control characters. Specifies that the terminal
operates in VT100 mode, using 7-bit characters for both input and out‐
put. Specifies that the terminal operates in VT52 mode, using 7-bit
characters for both input and output. Specifies the device attributes
response (Terminal ID). The device attributes response lets the host
system know specific operating attributes of the terminal. The Terminal
ID can be one of the following:
VT100 VT101 VT102 VT125 VT220 VT240 VT320 VT330 VT340 DECterm ID
The default is DECterm ID. Specifies that any text entered into
this field will be sent to the host when dxterm is requested by
the host to send its answerback message or when the user presses
Ctrl-F5. To include non-printing characters in the answerback
string, specify the character in hexadecimal notation preceded
by a pound sign. For example, the string #0D sends a carriage
return character to the host. To include a pound sign in the
answerback message, use the string ##. Specifies that the
answerback message entered in the Answerback Message text field
will not be displayed in the dialog box. Once selected, this
button cannot be deselected. The only way to deselect it is to
select the Answerback Message text entry field. This action
erases the previous answerback message.
Keyboard Options Dialog Box
The Keyboard Options dialog box lets you change the following keyboard
attributes: Specifies whether the warning bell sounds when dxterm
receives a BEL character (ASCII 7). The default is that the bell
sounds. Specifies whether the warning bell sounds when the cursor
reaches the right margin. The default is that the bell does not sound.

the display. If this option is not specified, the Ctrl-S and Ctrl-Q
key sequences are transmitted to the host as data characters. Speci‐
fies whether you can make copies quickly by using the mouse button
rather than cutting and pasting into this window. To perform a Quick‐
copy, select an object with MB2 and then release MB2 to insert the
object at the current cursor position. Specifies that the F11 key will
send the F11 keycode to the host. Specifies that the F11 key will send
an escape to the host. Specifies that a left single quotation mark (`)
(grave accent) is displayed when you press the `~ key and that a tilde
(~) is displayed when you press the Shift key and `~ key on a keyboard
using the North American or Dutch keyboard dialect. This setting is
the default. Specifies that the `~ key functions as an escape charac‐
ter (ESC) on a keyboard using the North American or Dutch keyboard
dialect. The default is to display the characters as labeled on the
keyboard. Specifies that a left angle bracket (<) is displayed when
you press the angle brackets key, and that a right angle bracket (>) is
displayed when you press the Shift key and angle brackets key. This
setting is the default. Specifies that a left single quotation mark
(`) (grave accent) is displayed when you press the angle brackets key
and that a tilde (~) is displayed when you press the Shift key and
angle brackets key. The default is to display the characters as labeled
on the keyboard. Specifies that the back arrow key sends a delete
(ASCII 127) character. Depending on your terminal settings, pressing
this key usually deletes the previous character. The default back
arrow operation sends a delete character. Specifies that the back
arrow key sends a backspace (ASCII 8, Ctrl/H). The effect of this
character depends on your terminal settings. The default back arrow
operation sends a delete character. Specifies that a comma is dis‐
played when you press the Shift key and comma key on a keyboard using
the North American or Dutch keyboard dialect. It also specifies that a
period is displayed when you press the Shift key and the period key on
these keyboards. This setting is the default. Specifies that a left
angle bracket (<) is displayed when you press the Shift key and the
comma key, and that a comma is displayed when you press only the comma
key on a keyboard using the North American or Dutch keyboard dialect.
It also specifies that a right angle bracket (>) is displayed when you
press the Shift key and the period key, and that a period is displayed
when you press only the period key on these keyboards.
7-bit NRCS Selection Dialog Box
The 7-bit NRCS Selection dialog box lets you select a National Replace‐
ment Character Set (NRCS) for use when the terminal is in 7-bit mode.
This selection affects output to the terminal, but not keyboard input.
To select the keyboard dialect, which does affect input, use the Key‐
board dialog box from the Session Manager's Customize menu. For exam‐
ple, to use the Spanish NRCS, select the keyboard in the Session Man‐
ager and also select the Spanish NRCS in DECterm.
To select a character set, click MB1 on the desired entry. The choices
are:
North American Flemish Canadian (French) British Danish Finnish Aus‐
trian/German Dutch Italian Swiss (French) Swiss (German) Swedish Norwe‐
gian Belgian/French Spanish Portuguese

longer supported; selecting Dutch is equivalent to selecting North
American.
Graphics Dialog Box
The Graphics Options dialog box lets you change the following graphics
attributes: Controls whether dxterm uses shared, read-only colors for
graphics. The default is Off, but the option is forced to On if the
hardware color map is read-only. Specifies whether dxterm creates a
pixmap to allow graphics to be redrawn when the window is exposed. The
default is On. Enables the ReGIS macrograph report command. The
default is Off. Controls the number of bit planes used for graphics.
VT240 emulation requires 2 planes; VT340 emulation requires 4 planes.
On systems with fewer than 8 hardware planes, the default is 2 planes;
on systems with 8 or more hardware planes, the default is 4 planes.
Print Options Dialog Box
The Printer Options dialog box lets you change the following printer
attributes: Specifies that a queued printer selected in the Options...
dialog box should be used as the printing destination. By default, the
Printer Port option specifies the local printer port. To choose another
port, enter the device name in the text entry box. By default, infor‐
mation printed on the screen does not create a file. Choosing the File
option saves the printed output to a file. By default, the None option
discards the queued job. To print characters use the Print Screen key
or use escape sequences. By default, a line of information is printed
if the cursor leaves that line because of an LF, VT, FF, or autowrap.
By default, each character is printed as it is received. If this
attribute is not selected, the character is displayed. By default, the
information on the display is printed but does not include information
stored in the transcript or status line. By default, the information
in the transcript followed by the information on the display is
printed. By default, the information stored in the scrolling region of
the display is printed. By default, the information in the selected
region of the display and transcript is printed. By default, only
national characters are printed. Other characters are either converted
to the corresponding national characters or the characters are not
printed. By default, national characters and line drawing characters
are printed. By default, all characters are printed, including multi‐
national and technical characters. By default, a form feed (FF) is
added at the end of each page. Alternately, an escape sequence can be
used. By default, any character read on the printer port is sent back
to the host application. This option is available only when the print
destination is a printer port device rather than a print queue or a
file. By default, graphics (bitmap) and text are printed. By default,
the graphics background color is printed. Omitting background color
saves ink and toner and maximizes printing speed. By default, a Sixel
introducer that omits the macro parameter is selected. This option
does not use the Sixel Set Attributes command to set the aspect ratio
and the horizontal grid size. As a result, the Sixel aspect ratio is 2
to 1 and the horizontal grid size is approximately 188 x 0.025 mm (7.5
x 0.001 inches). By default, a Sixel aspect ratio of 1 to 1 with a
variable grid size is printed using the Sixel Set Attributes command
(available with Level 2 printers). By default, a Sixel introducer with
the 9-macro parameter is selected. This results in a Sixel aspect ratio
of 1.02 to 1. By default, a compressed graphics image is printed. In
Portrait mode, the output fits on an 8 x 5 inch page. By default, an
expanded image is printed. In Portrait mode, the image fits on a
13-inch page. By default, an expanded image, rotated 90-degrees, is
printed. The output fits on a 8 x 5 inch page. By default, the Mono‐
chrome Printing option prints in black. By default, the Color Printing
option prints color output. DECterm includes a color map in virtual
memory to allow color printing from a monochrome system. By default,
this option sends only 7-bit control sequences to the printer. By
default, this option sends 8-bit control sequences to the printer. By
default, the HLS Color Syntax option specifies hue, lightness, and sat‐
uration (HLS). By default, the RGB Color Syntax option selects a red,
green, and blue (RGB) format when printing.

RESTRICTIONS
When saving dxterm options with the Save Options menu item, the entire
resource database is saved to the default resource file (~/DXterm or
~/DXterm_locale). A DECterm will, incorrectly, use the value in this
file to override other resource specifications. This can cause unex‐
pected behavior in any of the following situations: A dxterm is dis‐
played on a screen with a different depth from the one used when the
resource file was created. Command line switches are used in an
attempt to override settings in the resource file. The -setup switch
is used to try to prevent the default resource file from being read.
(The default resource file is read regardless.)
To avoid such problems: Do not use an unedited resource file created
with Save Options. If you want to set resources saved in this file,
edit the file, removing all resource specifications except the specific
ones you want to set. If Save Options created a resource file with the
locale appended (for example, DXterm_ja_JP), delete ~/DXterm if it
exists. Alternatively, delete the default resource file and do either
of the following: Create a resource file containing only the resources
you want to set and use it as an argument to the -setup switch. Use
the -xrm switch to specify the resources.
Chinese DECterm software supports using the DEC Hanyu, Big5, or DEC
Hanzi codeset as terminal code. The software does not support using the
Taiwanese EUC codeset as terminal code. To process characters in this
codeset, Chinese DECterm users should do the following: Start the Chi‐
nese DECterm software by using the zh_TW.dechanyu locale. For example:
% /usr/bin/X11/dxterm -xnl zh_TW.dechanyu In the DECterm window just
started, enter the following commands: % setenv LANG zh_TW.eucTW % stty
adec acode eucTW tcode dechanyu
At this point, terminal applications can process files that contain
Taiwanese EUC characters.
