title: Building a Modem Control Software: the connection part
body: <p>I have a 3G modem, and the accompanied "Mobile Partner" software really s*cks, and I want to make my own. Currently, I've found out the following:</p>
  
  <ul>
  <li>Sending/Interpreting AT commands</li>
  <li>Setting the APN/PIN/Network Registration/...</li>
  </ul>
  
  <p>These things were well-documented on many sites. But now I want to connect, and here the problems start:</p>
  
  <p>If I try to do a <code>ATDT *99#</code>, which should dial the *99# number, I get the message <code>CONNECT</code>. But what do I need to do now? How do I tell windows to use the dial in network? </p>
  
  <p>Is the '*99#' even the number I should dial? (I think so, because it's the default dialing number in the Mobile Partner application, and on OS X on my 3G modem)</p>
  
  <p>I'm writing this program in C#.</p>
  
  <p>Thank you!</p>
