Thank you for that information.

The reason for choosing DDE is that GNU emacs doesn't speak COM.
Every year or so I ask on the emacs-for-windows list, and every year
I get the answer no.

DDE is the technology that I have been using in ESS for sending
information to the S-Plus Commands window in the S-Plus GUI on
Windows.  I want to send information to the Rgui window on
Windows in the same way.

The Rterm window runs on Windows emacs in an *R* buffer exactly
the way R runs on Unix.  But it doesn't interact smoothly with
other Windows programs.

The specific difficulty that I want to solve now is the
interaction with RExcel.  RExcel and RGui work together smoothly.
RExcel and Rterm in an emacs *R* buffer do not work
smoothly (emacs buffers freeze requiring ^G to get control back).
