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.
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 and Free 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.
Conserver provides remote access to serial port consoles and logs all data to a central host. Local and network serial connections are supported. Server console history can be replayed from the console app even if the server is down, and multiple users can connect to a single serial connection.
NOTE is a small console program that allows you to manage notes similar to programs like "knotes" from the command line. It supports different database backends for storage, and includes a DBI-based MySQL module and another module that uses a binary file for storage and a DBM module.
