There's nothing wrong with trying to send those commands if the device really is disconnected. The attempts will fail quickly. The problem arises when the device is still connected but the driver has been unbound. That is illegal; a driver is never supposed to access a device once its unbind method has returned. Do other serial drivers suffer from a similar problem?
