I created an ssh terminal over browser back in the day (kind of like ajaxterm, but proprietary). I tried at least 4 different libraries over the years, but there would always be that one special device that refused to play ball. In the end I used an OpenSSH process, connected to it and drove it through input/output. Made those customer support calls really short: "Did you try connecting from the command line?"
