FlexTerm Terminal Emulator for IBM Z (Mainframe) via TN3270, IBM i (Power Series or AS/400) via TN5250 and Open Systems (Unix/Linux) via VT, SCOANSI or WYSE

Ribbon Interface

FlexTerm is written entirely in C# .NET, providing a new user interface that is long overdue for the terminal emulation community. The user interface utilizes the modern ribbon command bar to organize the program's features into a series of tabs at the top of the window. This increases discover-ability of features and functions, enables quicker learning of the program, and makes users feel more in control of their experience with the program. The ribbon replaces both the traditional menu bar and toolbars and is now fully customizable, allowing users to create their own custom tabs and tab groups.

FlexTerm Multi-Session

Multiple Sessions

A FlexTerm workspace can consist of a single session, or any number of sessions, which may be docked and displayed as tabs and/or floating.  Sessions within each workspace can be easily arranged using drag-and-drop functionality.
Any combination of TN3270, TN5250, VT400, VT100, VT52, SCOANSI, WYSE sessions can be configured in a workspace.

Window Management

Enhanced Session and Workspace window management provides the ability to navigate active sessions, dock/float session windows to/from the Workspace, cascade and tile either horizontally or vertically. Also, a Restore button is available to easily revert to a saved Workspace environment. This powerful function allows the user to undock session windows, resize and move them around and with a single click, restore to the saved size and location.
