The Video Terminal 100 (VT100) is a terminal that was produced by Digital Equipment Corporation (DEC). It was first released in 1978 as a successor to DEC’s previous VT50 and VT52 terminals.
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 VT52 terminal.
The VT100 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 VT100 escape sequences when certain keys are pressed.
The default arrow and function key mappings for the VT100 emulator are listed below. If needed these can be overridden using the Key Macro functionality.
| Key | Sequence |
|---|---|
| up | <esc>[A |
| down | <esc>[B |
| right | <esc>[C |
| left | <esc>[D |
| F1 | <esc>OP |
| F2 | <esc>OQ |
| F3 | <esc>OR |
| F4 | <esc>OS |
