[GreenKeys] 1 or 1.5 stop bits?

[Ralph Mowery]

You should use 1.5 stop bits if possible.

 

Some machines have used only one stop bit and you get a slightly higher
number of characters per minute.     I would have to look but not going to
but I think that is where the 66 wpm comes from instead of 60 wpm.

 

You may be able to get away with 1 stop bit, but 1.5 is needed and if more
than 1.5 such as 2 stop bits all you lose is a few wpm through put.

Sorry for rudimentary question. If I am configuring a serial port for use
with 45.45 baud ITA-2 mechanical teletype operation, should I use 1 stop bit
or 1.5? I can't recall the proper set up. And when RTTY users on the HF
bands what do they use?
