Question about the method of a saved frames log

I am a user on the XBee PRO S2B and XCTU ver.6. I have a question about the method of a saved frames log.

When Application sends frames continually by infinite loop, I want to automatically save log of frames every cycle.

If it is possible, please let me know about detailed method?

There is no way to save the frames automatically in XCTU, only manually.

You will need some other sort of tool to save the serial data automatically.
