title: Setting "Negotiate multi-link for single-link connections" through DotRas
body: <p>I'm creating a dialup entry in the ras phonebook, using DotRas.</p>
  
  <p>Everything works fine, only i can't figure out how to set that option.</p>
  
  <p>When i create the connection manually in windows and check that option in the PPP Settings everything works.</p>
  
  <p>If it's not checked, no internet access.</p>
  
  <p>Using RasEntry to define the entry.
  Opening RasPhoneBook (user) so there are no problem with user rights.</p>
