title: What does ^BOOT coomand means on Huawei E220?
body: <p>I have connected Huawei USB UMTS modem (E220) to my Linux box, i.e. RaspberryPi.
  Now I get 2 ttyUSB port available to communicate to it, where I use ttyUSB0 to establish mobile Internet connection and ttyUSB1 for other tasks, like sending and receiving SMSes, checking status and error codes, make modem configurations, etc.
  At regular intervals (2secs) I get this AT command on port ttyUSB1:</p>
  
  <pre><code>^DSFLOWRPT:n,n,n,n,n,n,n
  </code></pre>
  
  <p>which I fully understand (link: <a href="http://mybroadband.co.za/vb/showthread.php/21726-Linux-HOWTO-%28With-Stats%29/page37?p=715513#post715513" rel="noreferrer">thanks to the user user <strong>ginggs</strong> from http://mybroadband.co.za</a>). Less frequently I also get <strong>^BOOT</strong> command, looking like this:</p>
  
  <pre><code>^BOOT:12659389,0,0,0,58
  </code></pre>
  
  <p>Can someone explain what those numbers in ^BOOT mean? Can I make notifications/warnings in ^DSFLOWRPT and ^BOOT be less/more verbose (something like "errors on/off")?</p>
  
  <p>[edit]</p>
  
  <p>Added link for understanding the ^DSFLOWRPT command.</p>
