<DIV>So do you have any idea how at this low level I could determine the packet count so I could display it on my application screen? There is a byte count but that is not the same...</DIV>

<DIV>The code I see in the packetNtx download is not the same as the code supplied as a compiled .dll. This code section does not repond the the Sync flag and it also runs VERY, very slow... like one packet per second so the loop at "<FONT size=2><FONT color=#0000ff>do</FONT>{" must be broken.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Any help on pointing me to a fully functional packet dll will be appreciated.</FONT></DIV>
