The Video Terminal 52 (VT52) is a terminal that was produced by Digital Equipment Corporation (DEC). It was first released in 1975 as a successor to DEC’s previous VT50 terminal.
Both HyperTerminal and HyperACCESS include support for VT52 terminal emulation, which allows the software to be used to connect your computer to devices and systems that would normally require a DEC VT100 series terminal.
The 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 VT52 escape sequences when certain keys are pressed.
The default arrow and function key mappings for the VT52 emulator are listed below. If needed these can be overridden using the Key Macro functionality.
