CYBT-343026-01 is preprogrammed with EZ-serial FW (http://www.cypress.com/documentation/software-and-drivers/ez-serial-ez-ble-module-firmware-platform) before coming to market. So in any case the PUART port settings will be the same.
However in production time the initial state or settings depends on the application firmware you are going to program into the chip and platform file settings. (Platform Files for CYBT-343026-EVAL – KBA221025 ).
