A series of above exception block runs.

My program works fine .
This exception is thrown when I suddenly remove the modem attached to my 
running application.  
I want a graceful termination of the program without the exception block, 
whenever a modem is removed and causing the service thread to stop 
automatically.
Any clue to achieve this . 

Thanks in advance.
