The way you are running this, rterm has no connection to a keyboard, so
the answer is no. What you can do is wait until a quit dialog box is
clicked on.  Here's an example

winDialog("ok", "click to quit")

If you can arrange to pipe input to rterm, lots of other possibilities
exist, in particular those used for ESS (which uses switch --ess).
