Null-modem emulator
The virtual serial port driver for Windows.
The Null-modem emulator (com0com) is a kernel-mode virtual serial port driver for Windows. You can create an unlimited number of virtual COM port pairs and use any pair to connect one COM port based application to another. The HUB for communications (hub4com) allows to receive data and signals from one COM or TCP port, modify and send it to a number of other COM or TCP ports and vice versa. -

RealTerm: Serial/TCP Terminal
Serial and TCP terminal for engineering and debugging
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. -

ScriptCommunicator / serial terminal
Scriptable data terminal which supports several interfaces.
ScriptCommunicator is a scriptable cross-platform data terminal that supports serial port (RS232, USB to serial), UDP, TCP client/server, SPI, I2C, and CAN. All sent and received data can be shown in a console and can be logged in an html and a text log. In addition to the simple sending and receiving of data, ScriptCommunicator has a JavaScript interface. This script interface has the following features: - Scripts can send and receive data with the main interface. - In addition to the main interface scripts can create and use their own interfaces (serial port (RS232, USB to serial), UDP, TCP client, TCP server, PCAN, and SPI/I2C). - Scripts can use their own GUI (GUI files which have been created with QtDesigner (is included) or QtCreator). - Multiple plot windows can be created by scripts (QCustomPlot developed by Emanuel Eichhammer is used) -

Ada Terminal Emulator
A VTxx compatible terminal emulation package implemented in Ada
The Ada Terminal Emulator provides a rich set of terminal emulation capabilities, implemented in Ada 2012 (with some C) to run under Windows. All source code for the terminal emulator is provided under the GNU General Public License. The package was developed using GNAT and GWindows. In addition to providing simple "dumb" terminal emulation, the package provides full emulation of DEC VT52/VT100/VT102 compatible terminals, including double height and double width characters, smooth scrolling, special graphics, display controls and national replacement character sets. The emulator also implements a substantial subset of VT220/VT320/VT420, ANSI.SYS and ISO 6429 capabilities. The demo programs provided include a fully functional serial communications client, a telnet client, a program that allows stdin/stdout/stderr of any program to be redirected to a terminal window, and various other demos and games implemented using the package
