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.
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.
WinConnect is a software solution that enables Linux-based PCs and Thin Client devices (such as terminals, Internet/information appliances, and PDAs) to connect to a Windows server to run Windows applications over a network or via the Internet. The low-data transmission bandwidth required by WinConnect will even allow a remote connection over a dial-up or wireless connection to access data and run Windows applications wherever the user may need it.
