Not as old as RTTY, but it worked for a whopping 400 baud!............

Onoz. I used one of those.

My AF days in Telecom were at much lower speeds. 300 baud was called DSTE in my days. New fangled superspeeds called Digital Subscriber Terminal Equipment. My experience then was at 60 and 100 WPM.....baud rates were different when they were encrypted. (Removed the stop space).
