Could you maybe set a scan timeout for a shorter period of time, set that running on a thread, and have that thread check for some type of stop "signal" before scanning again? I think a Singleton pattern or something could work for this:
instantiate a "ScanMonitor" object that has a "Cancel" boolean property. (This can go to your scan() method)
Then, you could have another thread change ScanMonitor's Cancel property to "true" when you need to stop scanning.
set a while(true) loop to keep looping on that scan method with a short scan time, but before you scan, check if ScanMonitor.Cancel == true.
Does that make sense?

i think i could use some multithreading functionality like abort or interrupt thread, but anyway simpler is better.
thanks.
