So I am using cmdMessenger on a USB serial connection using the watchdog. Every time I sleep my computer and pull my desktop off the docking station. Once when the laptop wakes up I will get the following error and the app crashes.
System.ObjectDisposedException was unhandled Message: An unhandled exception of type 'System.ObjectDisposedException' occurred in mscorlib.dll Additional information: Safe handle has been closed

looking at a similar problem I found this. https://stackoverflow.com/questions/3230311/problem-with-serialport/7471010#7471010
I will do some more research and see if I can find a solution.
EDIT: BTW using .NET 4.5.2 on x64 Windows 10. It crashes with debugging on and off.
EDIT 2: Also found this. https://stackoverflow.com/questions/8927410/objectdisposedexception-when-closing-serialport-in-net-2-0 http://zachsaw.blogspot.com/2010/07/net-serialport-woes.html
EDIT 3: Couldn't find a trace within the code but enabling traces for native windows code I get this. Stack trace for SampleWatchdog
