1.7.16: problem with CTRL+C and CTRL+Z

1.7.16: problem with CTRL+C and CTRL+Z

[Rob Siklos]

Hi Cygwin List,

I've read some messages on this topic, but haven't been able to find a  
resolution to my problem.

Here's what I'm doing at the bash prompt:

$ /c/Windows/system32/ping.exe -t cygwin.com

The result is an endless ping trace - as expected.

The problem is that I have no way of stopping this command.  Here is  
what I've tried:
   1) CTRL+C: does nothing
   2) CTRL+Z: does nothing
   3) CTRL+Break: Prints the text "Control-Break" in the output, but  
doesn't exit the ping process (expected, since it behaves the same way  
when running under cmd.exe).

I would expect CTRL+C to stop the process (the way it does when  
running under cmd.exe).

I would also expect CTRL+Z to suspend the process, so that I could  
then manage it with "bg" and "fg".

I first noticed something was weird because when I upgraded cygwin  
CTRL+C stopped working (i.e. had no effect) when pressed in the middle  
of an "msbuild.exe" run.  Previously, this caused msbuild to stop.

Any help would be much appreciated.

Rob.

Did you read the part that said to try cygwin.com/snapshots for a fix?

Ok - my bad - snapshot works well for CTRL+C.

Seems like CTRL+Z only works for selected cygwin native processes.  If  
this is wrong, please let me know.

Thanks Earnie

Rob.

I believe that non-native Cygwin processes interpret Ctrl-Z to mean end 
of data.
