not realy, not without special apps running under the app. _One of those would be Screen. IF you had started screen, and then started the app, you now could get back to it from anywhere. But since it wasnt started inside Screen, theres little you can do.
It is possible to interact with the VC devices directly, but its very limited, and I havnt figured out how to actually interact with it. One can echo text into a VC, but it doesnt get fed to the app in it, but just displayed.
If its possible for you, just kill the app, start screen, and then start the application. Then you can continue it from anywhere, anytime.
is worth a read, and googling will probably yield more userfriendly instructions. if youre not already familiar with screen.
