Windows 10 supports ANSI Escape Sequences on the VT100 and derived terminal emulator technologies with 256 color extension. The a2h utility reads from standard input, or one or more files, and converts ANSI/VT100 escape sequences to inline HTML. You have three options: (a) Activate support globally by default, persistently, via the registry, as detailed in this SU answer. The trick is that a certain registry key must be set. Many computer terminals and terminal emulators support colour and cursor control through a system of escape sequences. Star 1. Leading zeroes are ignored. <ESC> represents the ASCII "escape" character, 0x1B. You can also use the equivalent 7-bit sequence, ESC (1/11) [ (5/11). The VT100 was introduced in August 1978, following its predecessor, the VT52, and communicated with its host system over serial lines using the ASCII character set and control sequences (a. Modified 7 years, 10 months ago. Linux terminal programs are usually full of colour, and it’s all thanks to VT100 escape sequences that date back to the early dumb-terminals. 9 any X11 color code can be written directly into a special escape QPlainTextEdit VT100 espace sequence support; QtWS: Super Early Bird Tickets Available!
