Many companies have implemented user productivity applications that work as Web applications, yet still have a terminal emulator running on the user's desktop. With Flynet Viewer or Screensurfer, the TN3270 applications can be integrated at the browser so that the users see a single menu, and can easily switch between Intranet applications and the TN3270 emulation session.
Do you Suffer from Emulator-in-a-Box Syndrome?
We call traditional TN3270 emulators ported to execute in the Web environment the "Emulator-in-a-Box" solution. That is because while users initiate emulation from a "real" HTML web page, the result is typically a separate window that pops-up and becomes the TN3270 emulator. This window is typically a Java Applet or an ActiveX control, and offers little integration with other HTML page objects, meaning little integration with your pages!
Another problem with TN3270 emulation delivered using an emulator-in-a-box is that enhancing the user interface is problematic compared to the ease of implementing an HTML-based enhancement with a product like Flynet Viewer. Large, clumsy graphical user interface code modules must be downloaded for every enhanced TN3270 screen which makes for stuttering and annoying delays. This doesn't even cover the low-level programming skills required to make a GUI user interface really work for a TN3270 screen compared to an HTML user interface.

Inventu provides our Customers with software and services to implement new applications that support business initiatives. Inventu concentrates on using, replacing and renewing existing (legacy) applications using our own product, Screensurfer and our Partner's product, Flynet Viewer.
Flynet Viewer has the best web-delivered terminal emulation on the market today. It provides the highest level of security, by keeping the mainframe connections behind the firewall and by connecting on the web with the highest level of SSL available today. It provides the highest network efficiency by utilizing HTTP compression and "send changes only" while supporting the new HTML5 web sockets when available. It provides the highest network compatibility by supporting traditional AJAX communications when the relatively new web sockets protocol isn't available.
For upgrading user experiences as well as building web service integration, Flynet Viewer provides "everything you need" and "nothing you don't want" for screen interfacing by development teams utilizing Microsoft IDE environments such as Visual Studio and ASP.NET on IIS

ScreensurferScreensurfer is an All-in-one host screen-to-Web application server that runs on Windows servers such as Windows 2000 and Windows Server 2003. Screensurfer is self-contained; no other products or development tools are needed to implement a new web-to-host application.
With an HTML-based tag language (Surferscript) which is very similar to Coldfusion CFML, Screensurfer provides very high productivity when converting existing 3270, 5250 and VT100 screens into HTML pages.
Screensurfer's IDE, the Express Editor and Debugger, provides an integrated editing and step-trace debugger for a solid editing and development environment that any developer can appreciate.
