Was there any other detail in your message? The forum doesn't support portable devices (tablet/phone)

How you do this will depend on your tool chain, and how that retargets/semi-hosts the stdio output.

In the general sense you'd set up USART2 via PA2/PA3 and then receive the data via the VCP (Virtual Serial Port) implemented through the ST-LINK, and create a putchar() type function to get data to USART2.
