Fast, even on a Hal ST-6000.  I think that most of these old agages were for 
Teletype (r) machine operation which is somewhat different than modern uses of 
RTTY.

There were/are all sorts of fine things like LTRS, and stuff that were 
necessary and special EOL sequences that are less useful anymore.
