The New Desktop does not support entering control characters in the login Username text field. If entered, these characters are discarded. This differs from the DECwindows login Username text field which supports such key sequences as:
The New Desktop does support Ctrl/U, which when typed while entering
a password at login or when unpausing the screen, erases any characters
entered up to that point.
2.3.15.2 Use Return Key to Move Between Login Text Fields
Because the Username text field and Password text field are different
dialog boxes in the New Desktop, press the Return key to move the
cursor from the Username text field to the Password text field. The Tab
key does not move the cursor to the next text field; rather, this
action highlights the OK button.
2.3.15.3 First Character Discarded When Entering Pause Screen Password
If the workstation is paused and the Password dialog box is not displayed, the first character typed is ignored. This differs from the DECwindows pause screen, which always accepts any characters typed.
When using the New Desktop, use a nontyping key, such as Shift, or
move the mouse to redisplay the Pause dialog box before entering your
password. If you are unsure of what you have already typed, you can use
Ctrl/U to erase the Password text field.
2.3.15.4 Text on the Welcome Screen is Not Displayed
If the 100-dpi fonts are not included in the X server's font path, the
welcome text is not displayed on the blue welcome screen that appears
immediately after logging in. This may also occur if you are displaying
your session on a remote X server.
2.3.16 Font Selection Limitations
On the New Desktop, Style Manager contains a control that displays a
dialog box used to select font size. Selecting a new font size affects
only New Desktop applications and does not affect existing
DECwindows Motif applications.
2.3.17 Default Workspace Limitations
The New Desktop provides a default backdrop for the four default workspaces. You can change or even select Nobackdrop using the Backdrop control located in Style Manager.
When no backdrop is selected, you cannot drag icons and place them on the backdrop of the desktop. If you drag an icon and release it, it snaps back to File Manager or Application Manager.
Icons that were dropped on the background before Nobackdrop was selected remain and function correctly.
2.4 Applications
The following sections contain notes related to specific DECwindows Motif
applications.
2.4.1 Bookreader
This section contains release notes pertaining to the Bookreader
application.
2.4.1.1 Bookreader Hangs When Switching Libraries
V1.2--6
When running DECwindows Motif Version 1.2--6 or greater on an OpenVMS Alpha Version 7.3--1 system, entering a library file specification that ends with a semicolon or a version number in the Selection field from the Switch Libraries dialog box causes Bookreader to hang.
To prevent this problem from occurring, do not specify a semicolon or
version number at the end of the file specification.
2.4.1.2 Support for Display PostScript Removed
V1.2--6
With the removal of the support for Display PostScript from the current version of DECwindows Motif, Bookreader no longer supports the display of PostScript artwork in online manuals. When Bookreader detects PostScript artwork, it displays a full-size figure window with a large "X" overlayed with an error message box containing the following message:
Unable to display PostScript(R) graphic. This feature is no longer available. |
There is no workaround.
2.4.1.3 Including Comment Characters in the DECW$BOOKSHELF File
If you include a comment character (! or #) in the last line of the
DECW$BOOKSHELF file, Bookreader fails with a reserved operand fault. As
a workaround, ensure that you do not add comment characters to the last
line of the file.
2.4.2 CDA
This section contains release notes that pertain to the Compound
Document Architecture (CDA) Run-Time Services and CDA Viewer components
of DECwindows Motif.
2.4.2.1 Viewing Large, Color DDIF Files using eXcursion Version 7.1
V1.3
If you are unable to display large, color DDIF files while running the CDA Viewer from an eXcursion X Server session, HP recommends that you do one of the following:
V1.2--6
With the removal of the support for Display PostScript from the current version of DECwindows Motif, CDA no longer supports the display of PostScript source. The PostScript option has been removed from the CDA Viewer. If you attempt to view a PostScript file from the character cell interface CDA viewer, the viewer displays the following message:
%CDA-E-UNSUPFMT, unsupported document format. |
There is no workaround.
2.4.3 DECterm
This section contains release notes pertaining to the DECterm
application.
2.4.3.1 Invoking DECterm May Fail while Kerberos is Enabled
V1.3
When using Kerberos authentication, the DECterm controller may fail to
start. The workaround for this problem is to change SYLOGIN.COM so that
Kerberos is initialized (@SYS$MANAGER:KRB$SYMBOLS.COM) within the
MODE_OTHER section of SYLOGIN.COM.
2.4.3.2 Euro Currency Symbol May Not Display Correctly When Using eXcursion
V1.3
Due to differences in how the euro symbol is supported between eXcursion and DECwindows Motif, the symbol may not display correctly on DECterm windows invoked via eXcursion. DECterm substitutes Latin-9 fonts with equivalent Latin-1 fonts, causing problems with the display of the symbol.
To prevent font substitution from occurring, modify the eXcursion font
alias files, as described in the eXcursion release notes. The release
notes describe how to edit the alias files, and describe additional
restrictions related to support of the euro currency symbol.
2.4.3.3 Window Text is Not Displayed Properly on Multihead Systems
V1.3
In a multihead configuration that uses the XINERAMA extension and Powerstorm 4d20 graphics cards, DECterm windows may not display text properly. However, keyboard input is still processed.
Refreshing any affected DECterm displays by running the XREFRESH utility from within each window will normally correct the situation. XREFRESH can be executed as follows:
$ RUN DECW$UTILS:XREFRESH |
V1.3
When you attempt to specify an Agfa Monotype TrueType font (such as the
DECterm font) using a wildcard in the font specification, DECterm
crashes. The workaround is to enter the full X Logical Font Description
(XLFD) name for the font (as listed in the hp DECwindows Motif for hp OpenVMS Alpha New Features manual) rather
than specifying the wildcarded font name.
2.4.3.5 DECterm Window Shrinking Problem
V1.2--5
If the XUI window manager is in use, "Auto Resize Terminal" is on, and you used the mouse to resize the DECterm window, the DECterm window shrinks. To workaround this problem, add the following line to the DECterm resource file DECW$TERMINAL_DEFAULT.DAT:
DECW$TERMINAL.main.terminal.useWMHints: false |
If you make this change, be aware that the window manager will report
the size of the DECterm window in pixels rather than character cells.
Also, if you maximize a DECterm window, it might not properly restore
to its previous size. However, it will no longer shrink.
2.4.3.6 DECterm Resource File Name
The locale of the display is now used to create the file name of the DECterm resource file. For example, if the locale is set to "ja_JP", then the default resource file name becomes DECW$TERMINAL_DEFAULT_JA_JP.DAT.
However, DECterm continues to use the old resource file name until the user selects Save Options at least once in the particular locale. The default resource file name for DECterm continues to be DECW$TERMINAL_DEFAULT.DAT if the locale meets any of the following conditions:
V1.2--4
A DECterm controller can create a maximum of 23 DECterm windows. This occurs because DECterm needs an event flag for each terminal window to use. There are 23 event flags that DECterm can use. (Event flag 0 and event flags 24--32 are not available for DECterm to use.)
If you need more than 23 DECterm windows, then you must create a new controller. To create a new controller, enter the following command:
$ MCR DECW$TERMINAL |
Note that the window from which this command is executed cannot be used
for anything else because this command does not return until the last
DECterm window is closed. After starting the controller with this
method, the user can create another 23 DECterm windows with the DCL
command CREATE/TERMINAL.
2.4.3.8 Resizing the Terminal
If you maximize the DECterm window when you enable the Auto Resize
Terminal window option, the window is expanded to its nearest cell
boundary; the window does not necessarily occupy the entire screen. The
Restore options continue to function appropriately.
2.4.3.9 Reporting the DECterm Window Size
When you enable the Show Feedback option in the Workspace Options
dialog box of the Window Manager and you resize a DECterm window, the
size of the window is reported in characters instead of pixels.
2.4.3.10 Changing the Auto Repeat Setting
You cannot change the Auto Repeat setting in the DECterm Keyboard
Options dialog box. Instead, change the setting in the Keyboard dialog
box in the Session Manager (Traditional DECwindows Desktop) or Style Manager
(New Desktop).
2.4.3.11 Positioning DECterm Windows
DECterm windows may not be displayed where the DECW$TERMINAL.x and DECW$TERMINAL.y resources are specified. On the Traditional DECwindows Desktop, DECterm windows are positioned incorrectly if the resource Mwm*clientAutoPlace is set to TRUE. As a workaround, set this resource to FALSE and restart MWM.
If using the New Desktop workspace manager, DTWM, then the relevant
resource is Dtwm*clientAutoPlace. Set this resource to FALSE
and restart the workspace manager.
2.4.3.12 Timeout for Displaying the Copyright Notice
If keyboard or mouse activity does not take place for 10 seconds after
the copyright notice is displayed on the terminal, the notice
disappears from the DECterm screen.
2.4.3.13 Selecting Fonts
Not all fonts work properly with DECterm. DECterm emulates a character-cell terminal, and, therefore, expects the fonts to be monospaced (each glyph occupies the same number of pixels). Proportional fonts can be chosen, but they produce unpredictable results.
Furthermore, DECterm fonts are supplied in families of 26 related fonts, including variations for bold, double-width, double-width/double-height, normal, and condensed characters. Also, DECterm fonts include special characters, such as the Line Drawing and the DIGITAL Technical character sets. A DECterm font family is identified by the font naming convention.
Use of fonts that do not have all the related font family variations,
fonts that do not have the needed special characters, or font families
that do not adhere to the DECterm font family naming conventions, may
not result in an optimal display or otherwise perform as expected.
2.4.3.14 Supported DECterm Logical Names
Table 2-1 describes the logical names that are supported by DECterm. If you do not define these logical names in your LOGIN.COM file, the controller uses the default values.
| Logical Name | Description |
|---|---|
| DECTERM_DIAG | Enables diagnostic messages. |
| DECTERM_SHOW_PARSING | Shows characters as they are parsed. |
| DECW$DECTERM_OUTPUT | Name of diagnostic output file; default is SYS$OUTPUT. |
| DECW$DECTERM_REGIS_CURSOR | Specifies which cursor to use for ReGIS. |
| DECW$TERMINAL_NODENAME | Node name used by controller if it cannot find another name. |
| DECW$DECTERM_CTRL_SSRWAIT | Sets the SSRWAIT flag for the controller to 1. |
| DECW$DECTERM_CTRL_PSWAPM | Sets the PSWAPM flag for the controller to 1. |
| DECW$DECTERM_CTRL_WSEXTENT | Sets the WSEXTENT quota for the controller. |
| DECW$DECTERM_CTRL_WSQUOTA | Sets the WSQUOTA quota for the controller. |
| DECW$DECTERM_DISABLE_QUOTA_CHECKING | Turns off quota checking. |
| DECW$DECTERM_MEM_DIAG | Shows controller quota calculations. |
Printing to a port device requires you to have read and write privileges on that port. You cannot print by allocating the device, since the controller requires access to the device. Instead, set the device to WORLD:RW.
For example, to use the printer port on a VAX 3100 system, enter the following command from a privileged account or include the command in the system startup file:
$ SET PROTECTION=WORLD:RW TTA3:/DEVICE |
If the hold screen key response time is too slow, add the following lines to your DECW$TERMINAL_DEFAULT.DAT file:
DECW$TERMINAL.main.terminal.syncFrequency: 1 DECW$TERMINAL.main.terminal.batchScrollCount: 1 |
Using these resources can affect the performance of the DECterm window.
The actual impact on performance varies from site to site. You can
trade off scrolling speed to hold-screen response time. A faster
hold-screen response results in a slower scrolling speed. The default
values for these resources are 10 and 0, respectively.
2.4.3.17 DECterm Graphics
The following information is specific to DECterm graphics:
You cannot create more terminal windows than your system resources and quotas allow. If you have insufficient resources, a dialog box is displayed with a message indicating that no additional DECterm windows can be created.
To reduce the memory requirement of each DECterm window and create additional terminal windows, decrease the number of Record Lines Off Top in the Display dialog box and decrease the number of columns for each DECterm window.
Once the resource limit is reached, log out of all DECterm windows that
are running on the host system before you increase the number of
terminal windows.
2.4.3.19 Diagnostic Crash File and Messages
DECterm produces a diagnostic file when a status code of fatal is returned. The DECTERM_ERROR.LOG file is produced in the login directory when the DECterm application exits abnormally. If you have a problem with the DECterm application, submit a copy of this log file to your HP service representative. However, under certain circumstances, a log file is generated even when no problem is encountered. Therefore, the appearance of a log file as an isolated event should not be cause for a problem report.
You can enable additional levels of diagnostic messages by defining either a logical name or a symbol named DECTERM_DIAG. When defined, enhanced diagnostics are displayed by the DECterm images. Use this mode only for diagnosing problems; it causes Session Manager message windows to be generated for each new DECterm created from the Session Manager.
DECterm diagnostics can be captured in a file by defining the logical
name DECW$DECTERM_OUTPUT to point to a file.
2.4.3.20 Using the Debugger
To redirect the output from the debugger to a DECterm window, enter the following command:
$ CREATE/TERMINAL/NOPROCESS/DEFINE=xxx |
This command creates a DECterm without an associated process but with a logical name of xxx that points to the terminal. This procedure enables you to direct output to a DECterm window other than the window where the application is currently running. To redirect the output, enter the following commands:
$ DEFINE /USER DBG$INPUT xxx: $ DEFINE /USER DBG$OUTPUT xxx: $ RUN /DEBUG application.EXE |
To create a process that uses a virtual terminal, enter the following command:
$ CREATE/TERMINAL/NOPROCESS |
Then establish focus to the newly created DECterm, press Return, and
log in. Note that the /DEFINE qualifier is not required.
2.4.3.22 VT330 and VT340 Terminal Emulation Restrictions
Although DECterm incorporates some of the features of the VT330- and VT340-series video terminals, such as ReGIS and Sixel graphics; it does not provide complete VT330 and VT340 terminal emulation.
The following restrictions apply to DECterm:
The /PROCESS=procnam qualifier does not work when used in conjunction with the /DETACHED qualifier, unless there is already a process running on the system where its process name is equal to the user name.
To work around this problem, use the following command procedure:
$! CREATE_TERM_PROC.COM
$!
$! Invoke as SPAWN/NOWAIT @CREATE_TERM_PROC procname
$!
$ SET NOON
$!
$! Set Process name to username
$!
$ X = F$CONTEXT("PROCESS", PID, "PRCNAM", "''F$PROCESS()'","EQL")
$ NAME = F$EDIT(F$GETJPI(X,"USERNAME"),"COLLAPSE")
$ SET PROCESS/NAME="''NAME'"
$ CREATE/TERMINAL/DETACHED/PROCESS="''P1'"
$!
$! Allow new process to RUN LOGINOUT before exiting subprocess
$ WAIT 00:00:10
|
If the /PROCESS=procnam qualifier specifies a process name that is already in use, the DECterm is created but creation of the process inside the DECterm fails. In this case, the DCL command CREATE/TERMINAL returns the following error message:
%SYSTEM-F-DUPLNAM, duplicate name |
