Release Notes

Reflection ZFE version 2.1.2 released June 2017. These release notes list the features and known issues in this release and information on how to obtain the product. Reflection ZFE provides terminal emulation for 3270, 5250, VT, and UTS host types, while requiring only an HTML 5-capable browser.

What’s New

  • Keyboard mapping enhancements. You can now map keyboard keys to actions, such as Execute Macro. You configure these actions in Key Mappings on the Settings panel.

  • There is now support for custom model screen sizes on 3270 terminal emulation. You can configure this option while setting your terminal model settings on the Connection page.

Known Issues

Technical Support is always available to help you with any issues you may encounter in Reflection ZFE.

NOTE:Reflection ZFE terminal emulation uses WebSocket technology for communication between a web browser and the Reflection ZFE session server. WebSocket is a feature of the HTML5 specification, and is supported by current releases of all widely available web browser software. If your organization has modified router or network configurations to disable WebSocket communications on your network, you cannot use Reflection ZFE terminal sessions.

  • Recommended browsers

    It is highly recommended that Reflection ZFE users use Google Chrome or Mozilla Firefox. While Reflection ZFE supports Microsoft Internet Explorer (IE) 10+, there are known performance issues with IE's JavaScript engine that may negatively affect the end user experience with Reflection ZFE.

    If you are using an older version of Internet Explorer, you may see these issues:

    There are remedies to both these issues, however the easiest solution is to use a different browser.

  • Key mapping

    Certain keys on a numeric keypad and some browser-specific keys cannot be mapped. For example, in Chrome, Ctrl+n and Ctrl+w cannot be mapped.

  • Some anti-virus software blocks WebSockets

    Reflection ZFE requires a WebSocket connection between the web browser and the server. Antivirus software might prevent WebSocket connections, especially when ports 80 or 8080 are used. If you think your antivirus software may be preventing WebSockets, first try a different port. For troubleshooting, see http://websocketstest.com.

  • Field outline in a 3270 session

    The 3270 attributes for field outlines are not fully supported. Reflection ZFE currently supports underline and overline; however, left vertical line, right vertical line, and combinations of the four line types are not yet supported.

  • SSL 3.0 is disabled by default

    For security reasons, enabling SSL 3.0 is not recommended. However, for hosts that absolutely require SSL 3.0, follow these steps to enable the protocol:

    1. Stop the applications or services that will be using SSL 3.0.

    2. Open <install-dir>/jre/lib/security/java.security in a text editor.

    3. Remove or comment out the line jdk.tls.disabledAlgorithms=SSLv3.
