An issue with uart and pic 18f452

Question

i have a problem with pic18f452 and uart i use simplest code like that:

 UART1_Init(9600);              // Initialize UART module at 9600 bps
 Delay_ms(100);                 // Wait for UART module to stabilize

and between forever while loop i have this code

  UART1_Write_Text("HELLO2");
  Delay_ms(1000);

also i have in my hardware lcd module it works very fine but my received data on pc is a scrap like that

???m

i have checked all connection sothand time nothing wrong also i have changed MAX232 ic but with no luck ?! my hardware is like that

finall all my connections are ok (polarity and every thing else ?) EDIT : i use mikroc as a compiler

Looks like a baud rate error. Have you checked that your oscillator settings are resulting in the expected frequency? Does the serial library you are using expect a certain clock frequency and you are sure that you are running at that frequency, or does it work over a set of frequencies and you have correctly informed the serial library what frequency you are using? Also it would be useful to see the byte received as a decimal or hex number rather than just ASCII.
