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.
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.
ZOC is a popular terminal emulator and telnet client that supports telnet, modem, SSH 1 and 2, ISDN, serial, TAPI, Rlogin and other means of communication. Its terminal emulator supports Xterm emulation with full colors, meta-keys, mouse support, and local printing; VT102, VT220, and several types of ANSI; and Wyse, TVI, TN3270, and Sun's CDE. Unique features include full keyboard remapping, REXX scripting, and support for connecting to named pipes.
psyced is a distributed chat and messaging system based on the Protocol for SYnchronous Conferencing. PSYC is multicast and routed between servers and clients in a scalable and efficient way, but users can also comfortably use IRC clients, telnet, Web chat, WAP, or Jabber to enter the network. psyced also communicates with the network of Jabber/XMPP servers and hosts programmable chat rooms for all of these technologies at once. It also provides gateways to several IRC networks, but unlike IRC, everyone can run a server and be an equal member of the PSYC network. It supports PSYC, XMPP, IRC, TELNET, HTTP, Applet, SMTP, WAP, XML, RSS, and TLS.
ConMan is a serial console management program designed to support a large number of console devices and simultaneous users. It supports local serial devices, remote terminal servers (via the telnet protocol), IPMI Serial-Over-LAN (via FreeIPMI), Unix domain sockets, and external processes (e.g., using Expect to control connections over telnet, ssh, or IPMI Serial-Over-LAN). Its features include logging (and optionally timestamping) console device output to file, connecting to consoles in monitor (R/O) or interactive (R/W) mode, allowing clients to share or steal console write privileges, and broadcasting client output to multiple consoles.
