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.
Exscript is a scripting language for automating network connections over protocols such as Telnet or SSH. It is in some ways comparable to Expect, but has some unique features that make it a lot easier to use and understand for non-developers. It supports parallelization, logging, authentication mechanisms, and a lot more.
Libtermui is a terminal driver library. It is fully standalone and lightweight. It does not rely on termcap or curses libraries. It can drive terminals on a TTY or through a telnet connection directly on a TCP socket. It is fully re-entrant, and can be used to drive multiple terminals from different threads. It includes a getline feature (similar to the one in readline) and some console user interface facilities.
