Inventu Viewer+ Setups 2026F1

by

Inventu Viewer+ Base Product and Components

(Version: 6.0.128 June 11, 2026)

Inventu Viewer Emulation Service

  • Hebrew and Right-to-Left text support has been added in VT and 5250 protocols.
  • The HE language code has been added to all selectable language lists and Hebrew has now been added to the translation list and is now an option for client help mouse-over tipText and messages.
  • In VT environments the host Report Printer Status command is now supported
  • In VT environments an option supporting sending a null after each Enter key
  • A VT320+ setting was added to enable discarding a CRLF sequence when inside a form-write indicated by a cursor lock at beginning of a buffer and cursor unlock at the end. A prospect’s host had a bug sending CRLF sequences in random locations while writing a new screen.
  • Added key mnemonics for control of Unicode Right-to-Left in user keystroking
  • When Device Printing, automatic detection of line length was implemented for a new print job to avoid the need to set active line length (80 or 132 columns) with an API.

FVTerm Web Terminal Emulator

  • Hebrew Support has been added for the end-user language setting for prompts and single-page help, as well as a number of changes throughout the product to support Right-to-Left text presentation and entry. At this time ASCII/VT support has the best implementation, with 5250 support working well when HTML Input fields are selected.
  • Added new Font “Cousine” which has excellent Hebrew support as the characters are well formed and contemporary in appearance.
  • Added new key mappings “heb” to switch to Hebrew (RTL) data entry and “eng” to switch to English/other Left to right. Heb will send 0xFE character (Start RTL) and Eng will send 0xFD (End RTL).
  • Norwegian (code “no”) added as a selectable client locale for messages and high-level help.
  • Active Directory/Windows Security was improved to better support user group membership in large organizations with a large number of groups.
  • A new Server Macro type named ClientEvents is now supported for handling events like MouseClick
  • Server Macro framework enhanced to enable more interaction with client as part of supporting conversion of PowerTerm PSL scripts as well as VBA scripts from other terminal emulators.
    • ClientJSCall – supports running a javascript function call at the client from the running server-side macro
    • ClientNewWindow – supports opening a new browser window from the client page using a URL and optional window name and other specifications for the window.open javascript call.
  • Added ability to have a mouse click on a VT/ASCII screen move the cursor to the click position—this was by adding new options to the Advanced setting Click Terminal Command which was at one point only supported for a narrow group of protocols. For general use, setting to “position” or “yes” will now enable mouse moving by single click.  This uses [left], [right], [up] and [down] cursor movement requests.
  • Improved support for numeric-only HTML-mode input fields as the existing support used out-dated HTML. This did not impact the default input fields that use the built-in Emulator mode keystroking and data entry.

Profiles Configurator

  • Hebrew (HE) added to all language selection options including CodePage CP424.dat for TN5250 and TN3270 host connections and CP1255.dat for TNVT connections.
  • Added new Access Block Group List option for Active Directory/Windows Security – can block a particular group (or allow access to only a specific group) when the URL used matches a pattern or the IP address indicates accessing the server from a public network.
  • Added Host Tuning option for TNVT protocol Ignore Carriage-Return Line-Feeds – when checked: when the host has “forms” which can be identified with a “hide cursor” order at the start of a large write building a screen and a “show cursor” order at the end (this is essentially locking the keyboard) all CRLF sequences are ignored.  Individual LF and CR characters are still interpreted.  This is to accommodate some host applications that have some kind of bug that emits CRLF sequence in the middle of screen content.
  • Added Host Tuning option for TNVT Send Null after Each Enter to mimic the behavior of some older terminal emulators.

ViewerLib API

  • findText(text, row, column, length, timeOut) added to enable searching for text on the screen with a timeOut, so that it can act both as a find method as well as a wait method in the situation where you want to wait for a particular string to arrive from the host (valuable in a VT/ASCII Protocol environment).
  • Internal updates to enable proper translation and access for Hebrew sessions (Windows Codepage 1255)
  • Added HostScreen Property VTIgnoreCRLF

Diagnostic Dashboard

  • When importing a configuration, added detection of Windows Security active in web.config so that IIS is configured to support Windows Security
  • Added new Version AI Chat: Open Chat Browser Tab Button accessing the experimental Inventu AI Version Chat – contact support@inventu.com for more information.
  • Improved messages displayed if user attempts to use the Diagnostic Dashboard without an active Maintenance agreement or subscription (which isn’t allowed).
  • Import/Export enhanced to include almost all settings and configuration files (adding those in the definitions folder for example) so that it is far more comprehensive when duplicating a configuration from one server to another.
  • Fixed bug with import that was placing all the profile and view settings in a temporary folder instead of the active one.
  • When viewing high-level explanations of found issues, can now copy an issue to the clipboard as well as open the Inventu HelpDesk Web ticket system at https://support.inventu.com/helpdesk
  • Added ability to extract user counts (Button Get User Counts) from the websocket log file, exporting statistics to a CSV file ready for import to Excel

Documentation

  • Added a few missing settings that had been implemented but not documented in the help.
  • Local help for the Profiles Configurator was updated to include new properties

Simulated Host

  • Ericom Trace files can now be used as a source for a Simulated Host script, the same as the Viewer Tracing FlyServ.log files can be (also Screensurfer log files). This enables testing exact sessions run using Ericom PowerTerm.

Inventu Viewer+ Setups 2025H1

by

Inventu Viewer+ Base Product and Components

This version provides significant improvements in Accessibility, important for our Federal, State and Local Government Customers who wish to address requirements in the United States by April of 2026/2027, and European organizations  that need to adhere to the European Accessibility Act (EAA).

(Version: 6.0.117 August 8, 2025)

FVTerm Web Terminal Emulator

  • Major Accessibility Enhancements – Multiple tweaks were made to HTML throughout the runtime client interface to address accessibility guidelines and requirements in both Europe and the U.S.

    • Welcome screen with connection tiles—is now fully navigable with the keyboard with necessary ARIA and role tags to fully support tools like NVDA and Jaws to deliver help and guidance for sight impaired.  When screen-to-speech tools like ARIA are in-use, additional title text (translated to the user’s language) provides spoken help on how to start a host connection.
    • The initial Help Page for operating the terminal emulator has been made fully accessible with all elements accessible with the keyboard. This includes being able to tab through each of the tool bar icons and receiving spoken descriptions of each icon.  Combined with FVTerm’s support for many non-English languages which are all translated on this top-level help, this is unmatched accessibility (don’t forget non-English speakers along with vision and physically impaired!).
    • Once connected, the terminal emulation page has been restructured to better support screen readers—5250 and 3270 entry fields were not integrated with the read-only text (labels). They are now and work very well and tested with NVDA which has no trouble with the FVTerm page structure.  In our tests with other HTML-based terminal emulators we found that NVDA only speaks one character at a time, due to each character cell being its own SPAN tag (!)
    • The tool bar icons are now keyboard accessible (default=Alt-M) and navigable with tab and arrow keys. This enables a user to fully access all functionality with the keyboard as well as when sight impaired.
    • The Settings Dialog is now fully keyboard accessible with all necessary roles and ARIA elements to enable accessibility to the configurable options.
    • If there are Macros defined, a user can now open the Macros Access page and navigate and activate available macros with the keyboard.
    • The Configuration can now set the HTML lang attribute to match the host screen’s language to better support screen-to-speech functionality (see below).
    • A previously implemented feature is also important for accessibility—the setting the enables a user to set a minimum font height and width…this ensures that the text can be very large and will be readable with vision-impaired users. This avoids the need to constantly zoom as the setting persists across all screens.
    • Also important is the ability to configure toolbar icons as “large” when this used to only be implemented for touch devices. Large toolbar icons can generally be more desirable with today’s large monitors whether needed for accessibility or not.
  • The Keyboard Configurator at the server for administration has had a bug since 2024 for saving changes to the SCKeyDefs.js file. It would ask the same questions as asked a user at a client web browser and then not display the javascript text to update the file with.

Profiles Configurator

  • The new configuration option Profile / Common / Screens HTML Language Code has been added. This provides the ability to set the HTML “lang” attribute for the emulator iFrame if the target host has a different language than English.  For example, if a host displays labels and data in Spanish, it enables screen readers and other assistive technologies to better interpret the host terminal emulation text when the correct language is in the HTML lang attribute.
  • Some fixes were made to logic that would hide or would show a property based on other property values.
  • Prompts were improved during the “add a new host” recognition text step to make it easier to understand how to draw a box around identification text for the first host screen.

Configuration Documentation

  • Added documentation for the new configuration option Profile / Common / Screens HTML Language Code.
  • Added a few missing settings that had been implemented but not documented in the help.

Inventu Viewer+ Setups 2025E1

by

Inventu Viewer+ Base Product and Components

(Version: 6.0.116 May 23, 2025)

Inventu Viewer Emulation Service

  • ASCII protocols backspace could result in invalid cursor location under rare circumstances. Will now wrap to top of screen if protocol supports it.
  • DBCS blank characters escaped with matching start/stop (0x0E/0x0F) characters instead of just stop, to ensure compatibility with some DBCS environments.

FVTerm Web Terminal Emulator

  • DBCS data entry fixed for certain situations discovered in Korean character set where the blank characters was not be properly escaped. (2025A2 6.0.116B)
  • Improved Session management to reduce incidence of session closing not always freeing the user’s session immediately.
  • With “Stretch to Fit” not active, certain fonts, such as Courier New, were not scaling with very high-definition / high resolution screens, resulting in a tiny screen font that looks like a stamp on the screen! The fonts affected are standard fonts with Windows (instead of optional embedded fonts supported by FVTerm). The reason was that the largest font defined internally was still too small to fill the screen which found a bug in the scaling logic. This is now fixed so that no matter how large the monitor screen resolution, fonts like Courier New will display correctly using the largest defined font. Note that having the “Stretch to Fit” active avoids this bug, but screen fonts will be “choppy” for fonts like Courier New on very large resolution monitors.

Diagnostic Dashboard

  • A new “Get User Counts” button on main dialog enables analysis of unique user accesses that is exported to a .csv file that can be loaded in Excel. This provides reading one or more WebSocket log files to extract user access statistics. If a server has IAM implemented, the user statistics will be based on the user’s identifier, most commonly the user’s email address.

Installer

  • For new installations, the checkbox to control displaying the /config/admin.html web page to continue the configuration no longer is displayed. Many users automatically uncheck these out of habit and this disrupts the completion of a new server configuration.
  • New host wizard has improved prompting to ensure user’s properly draw a box around static text on first displayed screen in order to ensure fast connections.

ViewerLib API

  • HostScreen.CopyToScreen fixed DBCS issue with blank escapes not always matching, which led to errant characters during data entry, discovered in Korean screens.
  • HostScreen LogDeltaError provides better information if an update results in a screen display error
