If a device is connected to the serial port and it becomes disconnected, does this close the port (after it has been successfully opened)? If it does, is it possible to detect that the port is trying to communicate to a non existant device?

TIA

I don't know the answer to your question. You might try checking the port status with $Port->status. I just ran into a similar problem with talking to a device's serial port that has been reset. For some reason, the '$Port->get(TimeOut => 1)' hangs when the device's serial port has been reset. Normally it times out after 1 second.
