Inventu Viewer+ Software Updates

• New Features:  FVTerm Crosshair Cursor Option and Mouse Wheel Screen Paging
• Further Continuous Updates, Enhancements and Fixes

Inventu Flynet Viewer Base Product and Components
(Version: 5.0.382 October 21, 2019)

FVTerm Web Terminal Emulation Feature

• The cursor can now be set by the user and Profile default as “Crosshair” which displays a vertical line to the left of the cursor location and horizontal line below it. The color and width of the line can be set with the Profile configuration by an administrator.
• The user’s Mouse Wheel can now be programmed to control paging of screens—can be set by an Administrator using the Profiles Configuration Page.
• 5250 Auto-Entry Input field support added – on filling an AutoEntry field, the emulator will send an ENTER key for the user.
• Keyboard mapping tool can now remap a key or key combination to enter any of the standard characters A-Z as a keystroke.
• Added support for Menu Item detection for non-5250 protocols. Prior versions automatically added menu detection and made menu items clickable if the protocol was 5250. Profile new property “Detect Menu Items and Make Clickable” will default TRUE for 5250 and FALSE for other protocols but can be changed to enable/disable this feature.
• 5250 Right-Justify Numeric fields with Field Exit keys inconsistent with large fields (more than 20 characters). Fixed in this release.
• When FVTerm is in an independent browser window (not in an iFrame controlled by the FVTermParent.js API), when moving focus between the emulator tab and other browsers/desktop applications, if focus is returned to the FVTerm browser window through any means, the keyboard will now process keystrokes. Prior versions required clicking-into the FVTerm browser page to re-activate the keyboard.

Setup, Profiles Configuration and Runtime

• The Profile setting Cursor Style now include Crosshair as a default option.
• Added new Profile settings for Crosshair Cursor Mode: Color for Crosshair Cursor Mode and Width for Crosshair Cursor Mode.
• Added new Profile settings for the new Mouse Wheel feature: Mouse Wheel Sends PageUp or PageDown Keys, Mouse Wheel Page Up Key and Mouse Wheel Page Down Key – the tool will provide a list of standard Enter, PageUp, PageDown and Function keys to be sent as part of the new Mouse Wheel option.
• Updated Configuration online help to include new settings that had been added over the last few months.
• New option “Detect Menu Items and Make Clickable” provides control for detection of on-screen menus (see FVTerm Client description of this feature).
• When adding a new Host definition, prior releases were not automatically bridging to creating a new Profile based on the new Host, as well as not refreshing the treeview list of active host definitions.
• New Host definitions settings for “DeviceID / LUName / Answerback” and “Custom Device ID / LUName Template” were being stored incorrectly in the registry, leading to Editor errors while changing the settings. Fixed in this release.
• New setting for ASCII Host definitions – “Treat Line Feeds as Carriage Return / Line Feed” which defaults new sessions to starting a new line at the leftmost column instead of simply indexing down one row. Some hosts will display initial messages oddly formatted without this option. Prior versions have this setting in the registry and required using the registry editor to activate this mode.
• For ASCII hosts, the “Scroll History Maximum Lines” was only working if set in the web.config file, not in the Configuration Profile

• Further Continuous Updates, Enhancements and Fixes

FVTerm Web Terminal Emulation Feature

• Added “Unlock and Refresh” as a keyboard assignment function, which works the same as “Reset Screen (host)” but is easier to recognize. Made Ctrl-R by default a Refresh to match common mappings in desktop terminal emulators.
• Made Ctrl-D by default a StartCopy function so that users can initiate a Clipboard copy without needing to click on the icon.
• When a key was mapped with Ctrl, like Ctrl-D for StartCopy, depending on how fast the user clicked the mapped key, the action could be defaulted to the browser function for that combination (fixed).
• Internet Explorer had an issue with clicking-in to portions of the emulator causing loss of focus for subsequent screens (fixed).
• Printer Device ID was displaying in settings when it was not needed—saving the printer device ID to local or server storage from the settings dialog was also inconsistent (fixed).
• Fixed some z-index issues with the new IntroHelp.html popup where some existing elements were displaying in front of the help.
• With 3270 clients, if a large password input field spanned multiple rows, the input by the user would be padded with blanks (fixed).
• Clipboard drawing mode for Copy was inaccurate when the Icon Tray was configured at the top of the page (fixed).
• Websocket server handler was vulnerable to a buffer overflow resulting in a loop in the handler Task. Indication that this is happening is CPU pegged at 1 / vCPU’s in the W3WP process for the FVTerm v4.0 IIS Application pool.  May have been related to poor network connections…fixed in this release.
• If a null character was included in a TN3270 datastream input/unprotected field, it resulted in truncated data for the field—fixed in this release.
• The FVSessions Session class SetFocus now defaults to not also placing focus into the emulation document’s body. An additional Boolean parameter was added to control that functionality (defaulted off).
• Added the session.SetFocus(focusOn, activate) function to the FVSessions API, to provide solid deactivation and activation of an FVTerm instance. This helps avoid unwanted focus events in multi-framed environments.  When focusOn is true, the activate parameter controls if focus is explicitly set into the FVTerm body—if not present or false, no explicit focus will occur.
• FVSessions Session.Transactions function now treats a command with no “^” character as a “I” command. In other words, straight text is simply treated as a hllapi keys command.  So “abcd@T” works the same as “I^abcd@T”.
• FVSession Transactions composite hllapi call was not calling its completion function if a composite hllapi string ended with an empty command or other unrecognized action code (fixed).
• FVSession Transactions composite hllapi call tweaked so that a plain hllapi string like “@C” will be treated same as the I^@C “enter keys” sequence. Prior to this tweak, the @C would not be sent and the completion function not called.
• FVSessions.js Transaction function updated so that the ^I command is now run in the client up until a host action key (like Enter or Clear) is needed. This enables the use of some fragments that only do tabbing and data entry but may not involve an enter.  This update also adds a new function in-support of the ^I command—FVSessions.Session.TypeKeys(text, screenWaiter).
• Enhancements and additional classes added to Server Macros to accommodate enhancements to the framework supporting conversion from desktop terminal emulator VBA macros

Setup, Profiles Configuration and Runtime

• Added automatic editing of stock HTML files that need the document.domain set. These files currently include SCTerm.html, welcome.htm, TopMenu.html, IntroHelp.html, ShowKeys.htm, Sessions.html and macros\MacrosMgr.htm.  If the PRESERVE comments have not been altered, the script block with a single line of document.domain=’yourdomain’ will be replaced into the preserved area.  This is in the Advanced section of the Web Server tab and makes setting the document.domain for all affected files easier and less error-prone.
• For a Profile, added the Recognition Application ID setting, which allows connecting a profile with a specific recognition definition file. This still requires editing of web.config to add the application key, but in many cases this is performed as part of code generation by Viewer Studio.
• For a Profile, added the Field Upgrades Active setting. When this Boolean is true the host or profile definition is expected to have a Field upgrades definition file active.  This requires custom support services interim to availability of a screen upgrade editor.

IND$FILE 3270 File Transfers

• A problem was discovered when rare network conditions caused buffers to be separated at the start of an IND$FILE execution on the host. This caused the transfer to fail with the message “ERROR: IND$FILE command failed, no transfer initiated–check host file name for validity”.  Fixed in this release.
