xtermcontrol enables dynamic control of XFree86 xterm properties. It makes it easy to change colors, titles, fonts, and the geometry of a running xterm, as well as to report the current settings of the properties. Window manipulations such as (de)iconify, raise and lower, maximize and restore, and reset are also supported. It also lets advanced users issue any xterm control sequence.
The xterm program is the standard terminal emulator for the X Window System. It provides DEC VT102/VT220 and Tektronix 4014 compatible terminals for programs that can't use the window system directly. If the underlying operating system supports terminal resizing capabilities (for example, the SIGWINCH signal in systems derived from 4.3bsd), xterm will use the facilities to notify programs running in the window whenever it is resized.
Mintty is a terminal emulator for Cygwin and MSYS with a native Windows user interface and minimalist design. It is based on parts of PuTTY by Simon Tatham and provides xterm-compatible terminal emulation, but does not require an X server. Its features include a simple options dialog, Unicode support, fullscreen mode, drag & drop, and window transparency.
dvtm brings the concept of tiling window management, popularized by X11-window managers like dwm, to the console. As a console window manager, it tries to make it easy to work with multiple console based programs like vim, mutt, cmus, or irssi. dvtm is intended to be used where X11 isn't available or over SSH. In conjunction with dtach, it can be seen as a lightweight alternative to GNU screen.
AKFAvatar is a fancy graphical user interface for text oriented applications where an avatar appears on the screen and provides information in a balloon. It also supports recorded audio files. Applications for AKFAvatar can be written in Lua, and there are interfaces for C, Objective C, C++, Free Pascal, and GNU Pascal. A number of ready-to-use applications and modules are provided, including a text viewer and a module that makes question-answer exercises. For POSIX-compatible operating systems there is a man page viewer and a terminal emulator, which makes it possible to run many existing terminal-based programs in this fancy environment.
GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
Cancan is a text-based, interactive utility similar to telnet, but with a number of extensions useful for MUD playing. Another use might be to provide line editing, aliases, etc., for those services that have a simple telnet interface. Cancan features aliases, actions, key bindings, text highlighting, substitutions, and line editing with history and completion.
