Not sure if anyone answered your question on this.  In order to see the bfgminer screen, you need to SSH (I use Putty) to your titan as user "pi" with the password you specified for "root" when you first entered the web interface.  Then type "screen -r" to bring up bfgminer screen.  To exit from the bfgminer screen use  "Ctrl-A" followed by "Ctrl-D".  That will disconnect you from screen without stopping anything.

I still have a die not working.  No further contact from Liam.  Maybe I hurt his fee-fees with my post.
