How to delete MSTPSimpleApplication and free all resources?

[EddieTheHead]

Hi, I would like to create and delete object derived from MSTPSimpleApplication to free serial port for another part of my application. I figured I can use bacpypes.core.stop() to delete it, but when I create a new instance it times out trying to read property. What's the correct way to kill MSTPSimpleApplication and then recreate it?
