logging not possible if exit command is part of the ini file

Hello,

I am testing an automated test run.
I am logging the output of the serial debug printf viewer.
This is the content of the ini file that will work after closing the uvision GUI:
g, main
slog > test.log

After executing the application, I can see that the log file gets created but it is empty.
The only time that the log file will have its content written is when I close the uvison GUI.

However, what I need is a fully automated test that should not require the manual closing of the uvision GUI before the log file gets its content written.

What I did is to edit the ini file and append the EXIT command as shown below:
g, main
slog > test.log
exit

However, this does not work.
I can see that the log file gets created but its empty and the contents were not written into it.
What seems to be the problem?
Adding a sleep or delay before exit does not solve the problem.
What can I do, please suggest some possible solution.

Thanks.
