Override configuration value in sequence

In reply to chr_sue:

Hello chr_Sue,

I am trying to change the configuration of the agent during run time.
My DUT is a UART controller and it has a provision to work in multiple modes with regards to its “sample rate” and “parity_type”. IN QVIP these values are configured at test. I want to override this configuration to see whether DUT is able to switch to the new settings for sample rates and parity.

could you let me know how this is possible?

Thanks.
