VT-AC EXAMPLES

This directory contains NodeJS example scripts that generate binary files for use with the VT-AC terminal.

Loading a file

Three ways, all equivalent — the bytes go through the parser exactly as if they had arrived over the serial port:

1. Control bar — the leftmost button, "Load data file".
2. Command line — vtac -l ./examples/characters.bin.
3. Settings panel — FILES → Load, which also remembers the file so Reload can run it again.

Generate a .bin first:

cd examples
node characters.js

Available Examples

1. bell.js: Generates a binary file that causes the terminal to emit all bell sounds when loaded.
   • Generated File: bell.bin
   • Build: node bell.js
   • VT-AC Command: vtac -l /path/to/bell.bin
2. characters.js: Displays all 255 characters in a 16 x 16 grid in the center of the terminal.
   • Generated File: characters.bin
   • Build: node characters.js
   • VT-AC Command: vtac -l /path/to/characters.bin
3. palette.js: Displays all 255 colors in a 16 x 16 grid in the center of the terminal.
   • Generated File: palette.bin
   • Build: node palette.js
   • VT-AC Command: vtac -l /path/to/palette.bin
4. ansi.js: Switches the terminal into 80-column VT-100 mode and draws a box with DEC line drawing, the four VT100 attributes, ANSI and xterm-256 colour, and a scroll region. Returns to the native personality at the end.
   • Generated File: ansi.bin
   • Build: node ansi.js
   • VT-AC Command: vtac -l /path/to/ansi.bin

The first three are native-personality files and work exactly as they did in v1.3.0. ansi.js is the one that needs v2: it opens with ESC 0x02 and ESC 0x03, the escape extensions that select 80 columns and the VT-100 personality, so it configures the terminal itself rather than assuming anything about how you launched it.

It leaves the screen in 80-column mode on purpose — switching back to 40 clears the screen, which would wipe the thing you loaded it to look at. Click the control bar's 80 readout when you have finished.
