Cisco WAN :: 1841 / Unknown Format In Console

I have got a problematic 1841 router. I connected it with console cable and use HyperTerminal application with

BPS: 9600
Data Bits: 8
Parity None
Stop Bits: 1
Flow Control: None
 
but the displays shows as follows. What may be the problem ? I can't see the English language, what to do now ?
