<DIV>Hmmm... the "find" function cannot detect that embedded within () I
guess. Thanks GV...</DIV>
<DIV> </DIV>
<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>
