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

This is one of my first .NET projects I did back in 2001. I wrote v2, supporting TCP/IP and Windows which was an upgrade from the v1 that was COM-port oriented and written by my father in QuickBasic eXtended (QBX) 7.1 around 1988. Not all ESC-codes have been implemented, only basics, which is all we needed. The only thing that was changed since 2002 is that I've upgraded the project to .NET Framework 4.8.1, fixed the creating of registry keys to store the settings and used Control.Invoke in 3 places where async methods are used, while apparently back in .NET 2 (I guess) that wasn't necessary. Other than that, all original code.
