Stopping OpenBSC

Bit of a random one, After I start Osmo-NITB is there any way for me to stop the process. I have had a look around the VTY interface, with not much luck. The only way I have found so far is by pressing CTRL+Z in the terminal window, but I then have to restart the computer to be able to start Osmo-NITB again. Many thanks, Ash
