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

windows()
plot(1:10)
winDialog("ok", "click to quit")
q()

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