Control A appears to be fixed. Sorry for the FUD.

Roger that. It took ten (10) plus years to get one word added to the Unix
installation document, and that didn’t even require a code change. To wit, the
addition of the word “minimum” to the phrase
“system settings,” which was perhaps one of the most annoyingly boring and
frustrating conversations had with about half of the 40-11 systems
administrators who balked at raising settings over the values listed in the
document, didn’t want to understand Oracle at all, and would not accept
responsibility for any deviation in the installation document.
Good luck with a ctrl-c on Windows SR. No telling whether that is ignored as
accepted behavior, hard to solve, or political. But I second Jared’s notion an
SR might help.
Try typing a control-A in on a non-important session some time. I wonder if
that has changed. I won’t spoil the surprise in case what used to happen still
happens…

CTL-C is handled differently on Windows than it is on any other OS that Oracle
runs on.
Linux for instance supports out of band breaks in the TCP stack, while Windows
does not.
When a database on a Linux service is supporting a connection from a Windows
machine, every 4th packet Oracle polls the client; kind of asking "are you
still there?"
The out of band breaks are how CTL-C is detected on linux clients, while on
Windows it is a polling operation.
It appears that there is a bug in the CTL-C handling for Windows clients.
It is kind of funny you referred to my 10 year old post on the topic.
1) the poster responded that sometimes Oracle is installed on Windows. yeah, I
knew that, as I had spend 8 years at that time adminstering Windows based
databases, but I did it mostly from Linux.
2) if thus is a bug, it is a very old bug. but sometimes you have to file an
SR to get a bug fixed. Two weeks ago I got fed up and filed and SR for a sqlnet
bug that has been around since at least 11gR2, but was still present in 19c.
you may want to create an SR. :)

Is there a solution for Ctrl C only to interrupt and not to exit SQL Plus in
windows.
