Hi,
Sorry, I do not think there is a way. I've put in a request for this and a
couple of other enhancements.
I agree that it is important that the handle be exposed.
If this is critical (such as for configuring Transmit timeout), you can
consider using DesktopSerialIO from my homepage -- while its object model is
simpler than that of SerialPort, it does expose the handle, etc. (though I
provide a method to change timeouts, so...).
