I've change and F_CPU,F_OSC from 16E6 to 8000000, also add CLKPR = 0x80 ;CLKPR = 0x00 ; to the first line of main().
So it works correct :)
May be problem solved.
But I want to ask you about setting Clock Frequency.
When I learnt to use ADC converter, My program only works with F_CPU is 16E6...
I connect Atmega168 to "FT232RL USB to Serial Adapter".
TxD -> RxD; RxD -> TxD;
This "FT232RL USB to Serial Adapter" connect to Computer via USB Port.
That is all my devices (Nothing else).
Is it not enough ?
Ok, I see. Thank for your help.
CLKPR = 0x80 ;
CLKPR = 0x00 ;
I've added two line about to the first line of main().
In Realterm screen, Received character is also special character (strange) in ascii mode.
So the problem isn't solved. Can you give me another solution?

(I also tried to use Hyper Terminal, but sometime text is...
