Windows X-server based on the xorg git sources (like xming or cygwin's xwin), but compiled with Visual C++ 2012 Express Edition. Source code can also be compiled with VS2008, VS2008 Express Edition and VS2010 Express Edition, although current project and makefile are not fully compatible anymore. Versions starting from 1.14.3.0 are not compatible with Windows XP anymore.

Serial terminal program for engineering. Ideal for development, reverse engineering, debugging, datalogging and capture, and automatic test. The website is a comprehensive manual for Realterm. It has an comprehensive ActiveX/COM automation support so it can be used a serial component by other programs. An extensive commandline interface supports batch files and simple automatic test programming. Commands can be sent to running instances, and commands can be stored and run in files. [ActiveX](http://realterm.sourceforge.net/index.html#ActiveX_Interface) and [Command Line](http://realterm.sourceforge.net/index.html#Command_Line_Parameters) commands are well documented. Sourceforge major releases are only made occasionally. To follow development versions see News and subscribe.

You can also easily share your recordings on the web, embed an asciicast player in your blog post, project documentation page or in your conference talk slides. See plenty of example sessions recorded with asciinema here: https://asciinema.org/

Terminus is a highly configurable terminal emulator for Windows, macOS and Linux. Features an integrated SSH client and connection manager. Provides theming and color schemes, fully configurable shortcuts, and split panes. Remembers your tabs. With PowerShell (and PS Core), WSL, Git-Bash, Cygwin, Cmder and CMD support. Enables direct file transfer from/to SSH sessions via Zmodem. Full Unicode support including double-width characters. Terminus doesn't choke on fast-flowing outputs. Allows proper shell experience on Windows including tab completion (via Clink). Terminus is an alternative to Windows' standard terminal (conhost), PowerShell ISE, PuTTY or iTerm. Terminus is not a new shell or a MinGW or Cygwin replacement. Neither is it lightweight - if RAM usage is of importance, consider Conemu or Alacritty.

Alacritty is the fastest open source terminal emulator there is. How is it the fastest? With such a strong focus on simplicity and performance, Alacritty’s included features are very carefully considered, ensuring that it remains blazingly fast. It’s got a GPU for rendering that makes a whole lot of optimizations possible. In various benchmarked terminals, Alacritty has shown to be either faster, or way faster than others. Alacritty requires no additional setup, but still allows configuration of many aspects of the terminal. It supports Windows, macOS, Linux and BSD.

Engineering, testing and debugging of serial communication. Supports RS-232/422/423/485 as well as TCP/IP Client/Server/AutoSocket, UDP/IP Client/Server/PairSocket and USB Ser/HID. Optimized for simple command sets of e.g. embedded systems.

This project provides a proxy that allows telnet/tcp connections to be made to serial ports on a machine.

Cmder is a lovely portable console emulator package for Windows. It was built out of sheer frustration due to the lack of nice console emulators on Windows. It is based on the amazing ConEmu, with major config overhaul, enhancements from Clink, Monokai color scheme and a custom prompt layout. Overall, it's got a very pleasant user interface that's much improved from ConEmu. The biggest advantage with cmder is that it is portable. It was designed to be totally self-contained, totally free of external dependencies. This makes it perfect for USB Sticks or cloud storage, so you can have your settings, aliases, binaries and history wherever you go.

tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached. This release runs on OpenBSD, FreeBSD, NetBSD, Linux, OS X and Solaris. tmux depends on libevent 2.x, and on ncurses. To build tmux, a C compiler (for example gcc or clang), make, pkg-config and a suitable yacc (yacc or bison) are needed. Some platforms provide binary packages for tmux.

SSVNC adds encryption security to VNC. It provides a GUI for Windows, MacOSX, and Unix that automatically starts up an SSL or SSH tunnel for connections to any VNC server. It also supports VeNCrypt encryption. The Unix viewer has many new features.

Console is a Windows console window enhancement. Console features include: multiple tabs, text editor-like text selection, different background types, alpha and color-key transparency, configurable font, different window styles

setserial is a program designed to set and/or report the configuration information associated with a serial port.

ConEmu-Maximus5 aims to be handy, comprehensive, fast and reliable terminal window where you may host any console application developed either for WinAPI (cmd, powershell, far) or Unix PTY (cygwin, msys, wsl bash). As Windows console window enhancement (local terminal emulator), it presents multiple consoles and simple GUI applications as one customizable tabbed GUI window with various features. Also, due to deep integration, ConEmu is the best companion for Far Manager, my favorite shell replacement. Disclaimer. ConEmu is not a shell, so it does not provide "shell features" like tab-completion, command history and others. But you can run any shell or remote access client of your choice in ConEmu! Try Clink for bash-style completion in cmd.exe and PSReadLine or PowerTab in powershell.exe. Or just run Bash from your favourite distro. Also, ConEmu does not provide remote access (SSH/Telnet/...) too, just use your remote client (ssh.exe, telnet.exe) instead.

Kitty is a fast GPU based terminal editor that allows you to offload rendering to the GPU for lower system load. Kitty works on Linux and macOS and uses OpenGL for rendering which makes it portable to other platforms similar to Unix.

mlterm is a multi-lingual terminal emulator , which supports various character sets and encodings in the world.

Linux is an excellent environment for deploying diskless thin clients. Whether you are installing a 2nd workstation at home, 50 workstations in a CyberCafe or 500 workstations in a major university or corporation, the LTSP can help you be successful.

This project now hosts the third-generation of Java SSH API, Maverick Synergy. This API builds on the Maverick Legacy commercial APIs and delivers a new API in a unified client/server framework. This API is available to the community under the LGPL open source license. This update includes ed25519 support, support for the new OpenSSH private key file format and stronger key exchange algorithms. The project continues to host both the original API and legacy applications created around it, however, these are now considered deprecated and we do not recommend their use in anyway.

TinTin++ is a console mud client for any type of text mud or bbs.

ConEmu is not a shell, so it does not provide "shell features" like remote access, tab-completion, command history and others. ConEmu is an advanced console window where you can run any shell of your choice. However, some of these features have been placed in the RoadMap. You may also try Clink for bash-style completion in cmd.exe and PSReadLine or PowerTab in powershell.exe. You can easily run old DOS applications (games) in Windows 7 or 64-bit OS.
