How to kill the socket connection

[Wang-Ruohan]

Hi, I met a problem with killing the connection to the robot.
I use the following statement to connect to the robot,
rob = urx.Robot("192.168.0.100")
However, when this program runs out and i end this program with ctrl+c, but not close the terminal. When i try to run the same program on the terminal i used before. It said:
urx.ursecmon.TimeoutException: Did not receive a valid data packet from robot in 0.5
it seems that i did not fully kill the connection, the previous connection occupied the socket i want to connect.
So, how can i fully kill it?

have you tried executing rob.close() ?
