Many people are affected by this double echo

I imagine that this is occurring because readline also echos the input:
https://github.com/apache/nuttx-apps/blob/master/system/readline/readline_common.c#L644
The low-level serial driver should not echo just because /isconsole
/is true. Console echo is always handled by the application. I would
say that that is a bug.

Hi,
I am connecting to my board using
python3 -m serial --raw --eol cr /dev/ttyUSB0 115200
This has ALWAYS worked.
Today it does not work anymore.
Every character I send to NSH is echoed TWICE, see below just typing
help:
----------------------------------
seb@lap:~$ python3 -m serial --raw /dev/ttyUSB0 115200

Only the echo is double, normal output is OK and characters are only
inputed once
Miniterm is not doing any echo. This worked fine before.
I have found that this commit is the problem
https://github.com/apache/nuttx/commit/68384e9db42e254b2cf6720bc3380aebdd2b298c
Reverting this fixes the dual echo.
I dont know what dev->isconsole does but
Just HOW can such a general breakage be missed by the super duper
cool testing that takes hours to complete?
Please STOP breaking NuttX, AGAIN
This is a lot of issues for a single day work.
Thank you
Sebatien
