dxterm - DECwindows terminal emulator
dxterm [options]
Specifies a value for a dxterm resource that overrides a
default setting. 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 respectively. 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.
The dxterm command displays a window that provides VT320
terminal emulation 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).

Specifies the characters which delimit a word when using a
double-click to select a word. The default is \ \t\r\n
(that is, space, tab, carriage return, and newline all
delimit a word).
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 unexpected
behavior in any of the following situations: A dxterm is
displayed 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 Chinese
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.
