Yes, a few. You might want to read my reviews on Strong Signals; you can find them as links off the software page. To start, check that com port slider on the main screen ; you will need to fool around a bit with it until you find a setting that is fast enough to run the scanner correctly *without* seeing errors, either during control or when you exit. It's almost impossible to state how fast your machine will go, due to com port differences and processor speeds; but somewhere in between 10 and 14 will get you started. It is a matter of experimentation to find the right results.
If you have other specific questions, fire away; and there's a Scan Control Yahoo group where Ken D. (the author) answers lots of tech questions. If I can't help - I've been working with SC since version 3.x - he certainly can. Again, that link exists on the Strong Signals software page.
Here's the link for the Strong Signals software page....
