Debugging

Escape Sequences are explained at http://www.xfree86.org/current/ctlseqs.html

A reference implementation of terminal.js can be found at https://github.com/c3ks/node-webterminal

I'm using a patched version of ttyrec, which enables stepping throught the output by pressing [space] or [enter]. See https://gist.github.com/Gottox/5432821 for the patch

For debugging it makes sense to set a breakpoint to the write() function at terminal.js. At least in Chrome, you can use this.toString(1) (or term.toString(1) in other classes) while debugging to get the current content of the buffer.
