[GreenKeys] Asr33: How are BREAK encoded ?

[Charles Morris]

The Break key simply interrupts the line (Space condition) as long as you have your finger on it. There is no start or stop bit, or coding, so you will get random garbage...

Hi guys, 

I taped several BREAK sequences with the tty puncher, pressing my finger more or less time on the key.
The punched codes differ a lot (see pic).
When I read the tape, toward my terminal via the usb current loop adapter, all BREAK are correctly converted.
Are they coded with several bits patterns ? If not, how are they interpreted correctly by the adapter ?

Thank you in advance,
Julien
