----------------------------------

       RESTART

   Restart the current connection; this is a kind of warm reset.  It
deletes the context used by this connection but does not actually reset
the card.

   This is used by gpg-agent to reuse a primary pipe connection and may
be used by clients to backup from a conflict in the serial command; i.e.
to select another application.
