If you enter ~B and actually see a ~B printed to the screen, then ssh
didn't process it because you didn't hit <cr> first.  So <cr>~B will
tell ssh to send a break.

... and if you're sshing to your terminal server, remember that ssh
will eat that tilde (because you sent <cr>~ ), so you need to send
<cr>~~^B to pass the right characters to FreeBSD.  Or change ssh's
escape character with the -e flag.
