Unexpected reading of console output #875
Description
Reported by tspivey on 2010-09-02 22:28
There are two instances I've found so far where characters are read unexpectedly in console windows:
- When echo characters is on and read dynamic content is off, the following at a Cygwin bash prompt will echo characters until ^c is pressed:
while :;do seq 1 100;done
This doesn't happen when character echo is off. - When read dynamic content is on and regardless of the character echo setting, the first character typed on a line will speak if there's nothing else on that line. E.g. starting to type an ed command.

Replying to tspivey:
I'm not sure there is really much we can do about this. They look like typed characters to our code because they're near the caret and they're single characters. It might be possible to work around this in Windows 7, where i believe we get real notification of typed characters via WM_CHAR. Mick, how is this currently being blocked for consoles?
Fixed in 6b0fdbe.

Actually, neither issue is fixed.
Another related issue is reading of spurious characters when cursoring through characters in a console editor with speak typed characters enabled.

When echo characters is on in Windows 10, the last line is spelled out in the console. So for example, when I am on my user dir it says:
c : \ u s e r s \ b r a n d o n >
C:\users\brandon>
one right after another. I do not remember this happening in windows 7.
It should just read the second line.

@tspivey can you still reproduce this in NVDA 2019.2 RC2? @codeofdusk does your highly appreciated work on console improvements with UIA solve this issue?

Is this a duplicate of #513?
Adriani90 commentedon Apr 25, 2020
@codeofdusk that issue was partly a duplicate.
@tspivey how is the behavior now in NVDA 2020.1 Beta?
Adriani90 commentedon Aug 12, 2021
Does anyone have an update wether this issue still occurs in last NVDA alpha?
codeofdusk commentedon Aug 12, 2021
This is a duplicate of #513 (fixed in 2019.3).

Closing as works for me. Thanks for the update.
