I didn't understand this part.

"you want to send a BREAK over the serial line. from cu, you do
this by typing ~# at the start of a line (i.e. press enter first).
If you're connecting over SSH, you need to escape the first tilde
since it's also used by SSH: ~~#"

I issue the "cu" command, it says Connected and after that I can't
really type anything. I get no cursor after I see "Connected" Is that
normal? Do I send BREAK only if I see POST messages from the Blade? Or
should I go ahead and type "~#" even if I see no cursor. Also, this
won't be over ssh.

Please Clarify.

Thanks a bunch
