There seems to be a language barrier here. Perhaps it would be easier to explain your requirement with a diagram...?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

By ''STM32-P103'' I assume you mean this:

Note that it has one RS232 port already - so you only need to add one other.

Study the documentation to see where the other UART port pins can be accessed on the various connectors on the board...

I see you have also posted the same question in a different thread:
