I have an app the is used to weigh in trucks on a truck scale. The app has a serial connection to a scale indicator. The app is constantly querying the data feed from the scale indicator so the weight displayed on the monitor looks live just like watching the weight on the indicator. This app has been working well for years but I have a new install running windows 8 using a USB to RS232 cable for communications. This install has been running there since June with no problems until recently and now I am getting errors that MScomm has lost connection. Two weeks ago I seemed to solve the problem by switching USB ports but today the problem came back. I am thinking that either the com port has gone away or MScomm control has crashed. This is very intermittent problem and I am having a tough time trouble shooting it. I was wondering if there is a way to trap the error and unload/reload MScomm?

Thanks.
