Do UART require data structure/format for serial communication?

Actually I am trying to data communication between these 2 chips, but facing
troubles in deciding a protocol to do the same.
Do UART have any default protocols? For the moment I am trying to do it with
Strings but not sure if that's the right solution.

Regards,
Vivek
