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.
DataReel is a free, cross-platform database and communications toolkit. It can be used to rapidly develop and deploy multi-threaded database and communications applications. The DataReel toolkit is composed of a modular C++ library designed to build cross-platform infrastructures for end-user applications, embedded systems, and reusable libraries. DataReel's unique modular design simplifies adaptation, allowing you to determine the level of complexity. DataReel makes Internet connectivity and database programming easy.
The Poor Woman's Telnet Server was quickly hacked together to provide a simple cross-platform telnet server. For non-Windows or non-Unix operating systems, you must adapt the call for the system shell. It is not advisable to run such an program on a production server, but for software development and testing purposes this program can satisfy some needs. It doesn't require a password and starts a system shell as the user who started the server.
