Anyone have current Packet32 source?
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 "do{"
must be broken.
Any help on pointing me to a fully functional packet dll will be appreciated.
Thnaks,
