<DIV>Anyone have current Packet32 source?</DIV>
<DIV><FONT face="Courier New" size=2></FONT> </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>
