Fingerprint scanner module problem...

Hi,

I am developing finger print access system. I am using P89v51rd2 microcontroller with WM 102 scanner module.... Both worked fine. but suddenly scanner module stopped response. it gives same output pattern irrespective of input command...
the pattern is...

17 02 12 10 02 09 00 09 08 00 00 00 00 00 00 00 00 00 14 05 08 04



So, what is problem here??

solved....
It was problem of terminal software....
