Hey paulie,

you asked how I did the web terminal on bbs.g00r00.com, so here's the
short version. It's actually not telnet at all.

1. ttyd (github.com/tsl0922/ttyd, I use 1.7.7) gives you a terminal in
   the browser via xterm.js and websockets.
2. ttyd doesn't connect to telnet. It starts a small Python wrapper,
   and that wrapper launches a local Mystic node in a PTY, pinned to
   80x25.
3. The wrapper translates CP437 to UTF-8 (otherwise the block graphics
   break in the browser). It also answers Mystic's cursor position
   request itself, because otherwise you get junk like "82R" in front
   of your username at the login prompt.
4. ttyd only listens on a local unix socket. nginx sits in front with
   HTTPS and proxies /term/ to it, websocket upgrade on, long timeouts.
5. A plain HTML start page wraps it in an iframe and scales the font
   so 80x25 fills the window.

And of course plain telnet on port 23 still works as usual, the web
terminal is just an extra door.

ttyd runs with -T ansi and a custom color theme. Honestly, the CP437
part was the only real headache, the rest is pretty straightforward.

Cheers
Goose
