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. -

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 -
