W7500 change baud-rate at runtime

i need help with a problem.
I have a program that wants to change the baud rate during runtime. The program runs on a Windows PC, where WIZ VSP Ver2.0.2 is also running. The computer is connected to a WIZ750SR via Ethernet. The WIZ VSP program also shows the change, but the WIZ750SR block does not implement the change. Is there a special procedure for this case?
We cannot reprogram the program that wants to make the change.
Thank you

As far as I know, WIZ750SR can’t change the setting value during runtime.
Just you can change the setting value the using Serial command.
In that state, the TCP/UDP operation is closed.
