<DIV><BR> </DIV>
<DIV>I would to know a which level Wireshark/Winpcap samples the IP packets.<BR>I use a mobile phone as a modem (DUN). A flow control permits to adjust the data flow from the PC to the modem.</DIV>
<DIV><BR>We have a downlink and a uplink data flow.</DIV>
<DIV>Because of this flow control, we can see that the downlink TCP data are not acknowledge immediately.<BR></DIV>
<DIV>I would like to know where wireshark samples the data?</DIV>
<DIV>When the data leave the ipstack or when the data leave the PC?</DIV>
<DIV>Can I configure wireshark/winpcap to sample the packet a layer 3?</DIV>
<DIV>(I am affraid it could have some important delay between layer3 -> layer 2 -> layer 1)</DIV>
<DIV><BR>(stack ip -> PPP -> USB -> modem) <BR></DIV>
<DIV><BR>Thanks a lot. <BR>Michel</DIV></td></tr></table><br>
