The Inventu Viewer+ Pure and Secure Web Terminal Emulator Server

Provides fast, direct terminal emulation using Zero-Footprint browser technology, with no plug-ins required.

Provides an excellent replacement option for organizations with existing solutions based on Java or ActiveX such as Host-on-Demand, Reflections for the Web and BlueZone.

The Right Answer for Today's Technology Questions

As more and more users work in and out of the office on a variety of devices, old approaches to delivering terminal emulation have become obsolete. "Bring Your Own Device" (BYOD) is here today and users need mainframe application access from multiple devices.

Many Web-delivered Terminal Emulators designed in the 90's utilized Java or ActiveX Plug-Ins to provide easy porting of code previously run in "fat client" desktop terminal emulators. These solutions will not run on any Smart Phone or popular tablets like the iPad and today only run in Internet Explorer 11. ActiveX-based solutions are particularly problematic as they only run on the Intel Windows Platform.

Java Browser Plug-ins are particularly problematic as Oracle has deprecated support as they have been linked to numerous exploits and security attacks. Most security experts recommend disabling Java in the web browser.

A Flynet Session Starts with a Click - In Any Browser, On Any Device

Meanwhile, the Inventu Viewer+ FVTerm application is pure HTML and Javascript with no plug-ins. It has also been finely tuned to run on all popular browsers and devices, with particular attention paid to support of touch-based environments.

With the Inventu Viewer+ Terminal Emulator, customers can get rid of their long setup and diagnostic pages devoted to helping web users connect with their problem-riddled Java and ActiveX solutions.

Responsive Design with Extensive Touch Support

The FVTerm Web Terminal Emulator will adapt to users devices and orientation. Desktop mode works just like a desktop terminal emulator while tablet and phone modes introduce tighter alignments and touch-based widgets.

Provided popular fonts scale to fit the available window size and additional fonts can be configured at the server.

Native Virtual Keyboards are used for most keying, as users are accustomed to using their device and the Flynet designers chose not try to replace this vital function. For those keys, such as the Function Keys and other unique terminal-style keys, a special keys virtual keypad is available and can be pinned to appropriate locations with a visual configurator.

Customer-Driven Popular Featues

As we have converted many customers from a variety of terminal emulators, users have requested support for features they really liked in their old emulator--here are a few examples:

  • Print Screen Grouping: The ability to queue multiple screen prints into one print job so that each page has two screens and so that all the screen prints are together in a shared printer environment
  • Clipboard Copy Column Detection: When copying a block of text from a screen that covers more than one row, detect where columns are and replace the blanks with a TAB so when pasting into Excel the data is in separate cells instead of grouped in one
  • Repeatable Block Clipboard Copies: When copying rows from multiple screens, a double-click on the Clipboard Copy icon will repeat the previous screens selection and automatically copy the same block to the clipboard
  • Cross-Hair Cursor Support: Vertical and Horizontal thin lines to mark where the cursor is (looks weird to some, loved by others!)
  • Support for Local Language: Many users do not speak English as their primary language and are better able to understand prompts, tips and messages when in their locale language.

Highly Functional and Easy-to-Use Configuration

Introduced in 2019, the Profiles-based configuration Administrator's framework enables high ease-of-use for finding and modifying settings

With Wizards to define new Host connections and user Profiles for accessing hosts, the Profiles Configurator supports the most simple single-host environment right up to an extensive IBM Host-on-Demand conversion involving multiple Views and custom access profiles

Multiple Security Options

Administrators can select between Integrated Windows Security, Microsoft Azure Active Directory, Google Sign-In, SAML 2.0 (Okta, SalesForce SSO), Custom Web Security or open access

When one of the security options is configured for the FVTerm application, when a user connects, the user's User Name/Email Address will be displayed in the Flynet Management Console session list. Other benefits of utilizing a Security option include grouping WebFlow Macros by Active Directory Groups so that users can have Flynet Macros specific to their work group.

While Security makes User Identity easily integrated, users can also be identified as they logon to the host system for use with the Flynet Session Logging Facility.

Minimal Network Impact with AJAX and WebSockets

Unlike first generation HTML-based emulators, Inventu Viewer+ utilizes keyboard buffering, Javascript web service calls and the exclusive Flynet Emulation DataStream - a fully HTTP-compatible, compressed emulation data stream. As a result, the network traffic is significantly less than with other HTML-based emulators - in fact only marginally larger than when using traditional emulators, and in some cases smaller.

Not a Fake Web Terminal Emulator

Inventu builds real web applications, not fake virtual sessions: FVTerm does NOT Require the HTML5 Canvas and HTML5 Websockets. But, we use Websockets if they are available.

Many newer offerings in the web terminal emulator market have taken existing solutions and run them on the server and turn the web browser into a virtual device--keystrokes and mouse movements are then sent flying around your network, ruining performance for both emulator users and other applications!

Strong support for VT / ANSI / ADDS-VP Character Mode Protocols

When a user is keying into UNIX/VMS/Pick systems, each keystroke must travel to the host with updates immediately traveling back to the user's display. Most of the time the user is simply keying text requiring only an "echo" of each character as it is keyed. The FVTerm application will only update the smallest portion of the browser display necessary which provides the best responsiveness and performance, even on slow connections.

Powerful and Extensible WebFlow Macros

Inventu Viewer+ includes a 100% Javascript client-side Macro recording, playback and scripting solution: Inventu WebFlow Macros. Webflow Macros are unique in the industry, as they can be instantly shareable across all users, as they are stored at the server. WebFlow Macros are superior to desktop solutions as they include extensions for Microsoft Office applications and can be extended with plug-ins for Cloud services such as Google Apps for Business and Government, SharePoint, Microsoft Office 365 and others.

Supports Incremental Modernization

The FVTerm Application is designed and integrated with the Flynet Screen Definitions facility. The Screen Definitions facility runs as the terminal emulator is connected to identify screens based on recognition criteria. When a screen is displayed that is identified as "enhanced", the Client Javascript Library runs an event so that a replacement web page can be displayed for the new screen instead of the standard emulation view.

This facility is enabled by the Responsive UX Upgrade Application Generator to enable support for both enhanced and un-enhanced screens in one web application.

Flynet Custom Session Logging and Single-Signon Support

Provided for customer use is a sample application written in c# (the popular .NET language) which is easily customized to provide extensive logging of user sessions. When combined with screen recognition and field mapping, user data entry fields can be identified in-context for custom logging to a database. For example, all screens where a user's social security number or credit card number may be visible can be logged with the userid accessing the information.

Inventu can also help customers implement administration-free Single-Signon, as the Custom Logging application has the ability to save a user's encrypted credentials for re-use on future logons (only available with Windows Security and Active Directory configured).

Client-Side Javascript Library

Also provided for customer use is a Flynet FVTerm integration library that plugs-in to existing customer web applications to provide easy integration of one or more Flynet FVTerm emulation sessions. New sessions can be launched and then events can be registered to capture new screen entries, displays and field contents both displayed and as they are entered by the user.
