[Elecraft] K3 UOS?

[Bill Frantz]

On the Teletype model 33 and 35, one character delay was enough 
for the carriage to return to the left margin. That made the CR 
LF sequence the favored new line. (The LF could be executed in 
one character time.) These machines used ASCII code as compared 
with the model 28 and earlier models which used the Baudot code 
we use for RTTY. I understand that these earlier machines had 
the same timing, but I never had any direct experience with them.

Indeed, if you used the LF CR sequence, you needed to insert a 
one character time delay for timing. A Rubout character was 
often used for this delay.
