title: gprs modem AT vz. data mode
body: <p>I'm using <a href="http://www.seapraha.cz/download/pls8-e_atc_v01000_tcm216-155309.pdf%20%22%22" rel="nofollow">Cinterion, PLS8-E</a>.</p>
  
  <p>I have opened socket connection through gprs, sending, receiving data. And I have information screen filled with:</p>
  
  <ul>
  <li>Network &amp; signal</li>
  <li>LAC/TAC</li>
  <li>CID</li>
  <li>2G/3G/4G connection</li>
  </ul>
  
  <p>All this information I'm getting from modem after powering up modem and before I bring up ppp0 interface and create socket connection through it.</p>
  
  <p>what I need is to periodicly update information screen and every 30 sec ask modem:</p>
  
  <ul>
  <li>"AT+CSQ"</li>
  <li>"AT^SMONI"</li>
  </ul>
  
  <p>How can I do this while opened socket connection throuh it?</p>
  
  <p>Or if you can point me to any web page where I can learn about this, it would be highly appreciated.</p>
