My friendo! u know what, U ARE RIGHT!!!
I need a 15 millisecond delay before I read the Serial Input buffer. How could I forgot that.
Anyway, William, thank you very much for helping me out! For all you guys taking time to read this, thank you for your time!

First of all, thank you very much for reply. Really appreciated.
OK, the difference.
For example, I've set the electrical unit ON, so, I suppose to see the "ON" status when I run the program. When I debug the code step by step, then I can see I got the right response from the controller and the status of the electrical unit is "ON", which is right. But if I just compile the code or run the *.exe file, the result is different, it show "OFF". I suspect there might be some problem with communication part, but I can't find it.

Sorry for the misunderstanding, I mean when I compile it, the result is different from when I debugging it.
