C Code for communications between PCB and computer?

I need to setup a communications between a microcontroller and a PC. They are connected via RS232 UARTs.

The drivers are written and I can use stdio like printf, scanf etc.

If I want the message to require a preamble '%' and end with a '\r\n' , how would I code this?

Are there any examples out there?
