VT220 VT320 terminal emulation software

The Video Terminal 220 (VT220) is a terminal that was produced by Digital Equipment Corporation (DEC). It was first released in 1983 as a successor to DEC’s previous VT100 series terminals.
The VT320 was released released a few years later in 1987.

Both HyperTerminal and HyperACCESS include support for VT220 and VT320 terminal emulation, which allows the software to be used to connect your computer to devices and systems that would normally require a one of these terminals.

The terminal emulator translates escape sequences from the system you are connecting to and uses them to control the terminal screen. Additionally the emulator maps the keyboard to send VT220 or VT320 escape sequences when certain keys are pressed.

The default arrow and function key mappings for the VT220 and VT320 emulators are listed below. If needed these can be overridden using the Key Macro functionality.
