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

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

https://www.olimex.com/Products/ARM/ST/STM32-P103/

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...
