Jubilant Web Based Terminal Emulator for Mainframe iSeries UNIX VMS and MultiValue

Jubilant Terminal Emulator provides a browser based, terminal emulator to access key business systems.

Access Mainframe, iSeries, Unix, VMS or MultiValue systems, on any device with zero client software.

The terminal emulator is installed in a server environment, either on-premise or in the cloud, and centrally managed via the Jubilant administration centre. Jubilant works on all browsers and devices with no Java or ActiveX plugins.

Jubilant has all the features you would expect in an enterprise terminal emulator, including client and server-side macro creation, file transfer, single sign-on, MFA and keyboard remapping.

Jubilant Terminal Emulation installs in minutes and connects automatically to systems like Mainframe, iSeries / AS400, Unix / Linux, VMS, VAX and MultiValue or most similar systems that use typical green screen connection protocols like 3270, 5250, VT220 etc.

These systems are then instantly and securely available via any web browser on any platform. In addition, the Jubilant server will dynamically recreate a responsive interface that reflects the typical use on the devise being used, for example on an iPad (any tablet) or iPhone (any smartphone) it will deliver a fully scaled touch screen interface with full pinch and touch support. On a PC or thin-client the Jubilant server will provide you with an interface that is more similar to a desktop Terminal Emulation client, again all delivered through the browser with no client-side software or plug-ins.

Jubilant Terminal Emulation provides the same level of functionality that is associated with a full fat desktop Terminal Emulation client but is delivered over the web and served up via a browser. Jubilant Terminal Emulation will run on any device regardless of operating system or indigenous browser, 100% pure HTML and therefore browser and platform agnostic, a true proponent of the BYOD generation.

Jubilant Connects to Many Popular Systems and Protocols

Our customers run large IBM Mainframes, some of the largest AS400's/iSeries in the world and a number of different UNIX/Linux variants as well as Pick / MultiValue Database systems. The Jubilant Emulation service connects to these protocols on one side and provides a uniform API on the other.

Supported Systems and Protocols:


  • IBM Mainframes - TN3270
  • AS400 / iSeries / IBM i - TN5250
  • UNIX / Linux / AIX - VT100, VT220, VT320, SCO ANSI, ADDS ViewPoint, Wyse 50, Wyse 60
  • DEC-VMS / OpenVMS - VT100, VT220, VT320
  • Tandem Nonstop - TN3270
  • Dell UNIKIX - TN3270
  • Pick / MultiValue - ADDS ViewPoint, VT220, SCO ANSI, Wyse 50, Wyse 60, AccuTerm

Supported Browsers:
  • Microsoft Internet Explorer 6 and above versions
  • Microsoft Edge
  • Apple Safari
  • Mozilla Firefox
  • Google Chrome
  • Opera



Supported Devices:

Jubilant Terminal Emulator will run on any device regardless of operating system, all that is required is one of the aforementioned web browsers to be present. Depending on the size and the interface being used Jubilant will automatically resize and rescale the interface to suit. If a capacitive (touch screen) interface is being used Jubilant will provide full touch support automatically converting appropriate objects for touch use, similarly pinch to zoom and other device native expectations are accommodated and delivered out of the box.



Multi-threaded Robust Server that runs as a standard Windows Service

A single Jubilant Server installation can support over 500 simultaneous clients (250 is recommended for high usage scenarios) at speeds which surpass the desktop equivalent solution. In addition, the multi-threaded core at the heart of the Jubilant Terminal Emulator server platform ensures a minimum network footprint, unburdening heavily trafficked networks. The Jubilant server runs on Windows Server (2008, 2008 R2, 2012, 2012 R2 and on Azure).

The Jubilant Server code was never part of a desktop terminal emulator; from its origins it was designed to be a highly efficient multi-threaded server side core service. This means that Jubilant Terminal Emulator can support more concurrent sessions on any given server configuration than any other browser delivered emulation solution.




All Jubilant Terminal Emulator  communications made between the server and host are made over a telnet connection secured by a SSL/TLS wrapper. All Jubilant communications made between the application server and the client are primarily conducted using WebSockets and where this is not supported HTTPs is used.

  • Supports Secure Sockets Layer (SSL v3.0 and TLS v1.0 SSL) encryption.
  • Provides SSL authentication using digital client certificates, user generated as well as third party. Standard authentication technology is built into Jubilant Terminal Emulator.
  • FIPS 140-2 Validated Cryptographic Module .
  • Supports NT domain authentication / Active Directory / Azure Directory authentication.
  • Supports most off the shelf and proprietary IAM and SSO solutions with templates available for integration.



Terminal Emulation API

You have the option of extending your terminal emulation experience using JavaScript. An API gives you access to screen read/writes. You can also access the emulation server-side using various Jubilant Terminal Emulator APIs for .NET, COM​​/​Win32 and EHLLAPI.


Comprehensive .NET API Library

Applications that utilize the Jubilant Emulation Service, such as the FVTerm Pure Web Terminal Emulator Web Application, do so with the Jubilant Terminal Emulator Lib .NET Application Programming Interface.
By the use of shared memory and native Windows Synchronization objects, the performance of the API through all ranges of application challenges is unsurpassed.
The functionality and proven performance of the API has been strengthened through a decade of directly developing customer applications with the API by Jubilant, as well as creating application generators that leverage its power.



Microsoft Management Console Snap-In

This standard Windows Administration Application can be run stand-alone or added to an Administrator's MMC environment to provide integrated runtime management of the Jubilant Emulation service. It is an excellent tool for both Administrators and HelpDesk personnel as users can be assisted directly through the use of the built-in terminal emulator.
It provides the ability to configure one or more Jubilant servers so that from one view, multiple Jubilant Servers can be monitored and managed.

Jubilant MMC Snap-In Features

  • Text-based configuration files allowing administrators to easily find and edit entries in the configuration files either manually or programmatically.
  • Multiple User Configurations
  • Provides dynamic device name/logical unit (LU) assignments based on log-in, ensuring users always get the correct display and printer sessions. Jubilant Terminal Emulator supports completely custom configurations assigned on a group or user basis, the number and types of sessions, and specific device or LU assignments.

Taskbar Notification Icon and Actions

Included with the Emulation Service is a handly applet that runs in the Taskbar Notification area. It provides status information on service starts, stops and restarts. In addition, it provides convenient menu items for launching various utilities as well as starting, stopping and restarting the service.
