Sending BREAK to a Open Gear console server

I am having some trouble configuring conserver to send a BREAK to an 
Open Gear console server.

The break sequence for this console server is ~b
When I am connected through conserver I can use ~b directly from my 
keyboard and get the right results (the host halts - ok)

In my conserver.cf file I have:
break 4 { string "~b"; }

On the conserver console connection when I use ^Ecl4 it sends a '~b' but 
this is not seen as a break signal by the console server, it is sent to 
the port as text, (and I get a response from the host - not ok)

What am I doing wrong?
