Thank you for your response Mr.Kevin Actually I also thought the samebthing due to the running shell only it gives the problem .but unfortunately the shell i'm unable to see instead of that only I got that import serial error . so that i have used GTKTERM (serial terminal sortware) in that i'm able to see the running shell and can give the ps help commends also but i can't able to stop that running shell in the openmote-B.i just want to know that how to stop or how to reset the board.
