You don't need the CTRL.

$ ~?
Supported escape sequences:
~.  - terminate connection
~B  - send a BREAK to the remote system

Use less fingers :-)

If that doesn't work, please post a debug trace, eg:

ssh -vvv terminalserver

Note that it's a capital B, so use shift not ctrl, and you must start 
the sequence with a carraige return.  You should see something like this 
in the output:
debug2: channel 0: request break
debug2: channel 0: written 4 to efd 6

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
