I've been able to get an event wired up for the actual device/serial port. Something like this:

NmeaInterpreter GpsInterpreter;

public static event EventHandler Disconnected;
GpsInterpreter.Device.Disconnected += DeviceDisconnected;

I was testing with a USB device, so it made sense and looked like it worked. Whenever I unplugged the device, it reported the disconnected event. However, testing on my desktop I didn't realize that unplugging the usb device removes the comport altogether.

What I was looking for was an event to tell me when the GPS puck was unplugged from the serial port, not when the serial port disappears. For now, I've found that I can use the ExceptionOccurred event, and that will be raised when the serial device is unplugged.

Is there a better way to tell if my device gets unplugged? I feel like the exception event could get me into trouble down the road, but it's the best I found so far.
