Receiving data on UART with STM8L

Question

i wanna to know that, is there any thing to do for sending data on UART to STM8L? i wrote a code that was similar to others and i think my hardware is okay. i send some data to STM8L with PC by terminal software. here i think i should first send some data that it detects the start as it was described in datasheet. now what should i do? excuse me for my syntax error. thanks for your help :)

I also meet the same problem. I just re-configure system clock is done. My way:

/High speed internal clock prescaler: 1/

CLK_SYSCLKDivConfig(CLK_SYSCLKDiv_1);
