Connect state RS232

Hello
I have a problem with the Gadgeteer RS232 module. Is it possible to see when the cable from the PC is connected and disconnected
to the controller ? I want to write the Connected State to the Display. I can’t find an event so is it possible to get the status with a workaround ?
I’m using the hydra module.

There is no way but applications usually rely on a small message, a heart beat, to detect that the proper device has been connected.
