As far as I'm aware, there isn't any type of terminal which will allow you to display an iDevice on your computer. However, you can just plug it into your computer and iTunes should still recognise it and show you most of the details.
Also, there is a piece of software called DiskAid which will allow you to see much more information than iTunes displays without having to jailbreak the device.
You'll be able to find all the information you'd need by using these programs. However, if the device has a pascode on it there's not really much you can do as it will prevent the computer from accessing the device.
