You can program a negative delay in your close call settings, or try sending "KEY,S,P\r" after your own delay to resume scanning.Okay I was able to get a screen shot of a close call.
Part of the info passed back from the scanner says close call, so it would be easy to log just the close call hits.
Problem is when the scanner gets a close call it stays on it, until you interact with it. This is no good.
Is there a way to tell it to hit on a close call wait for x seconds and look for another one if not logging them would be pointless.
