As shown in the figure: WPE is a software that can receive and send data packets of network card. Can ce7.0 also be implemented.
There are two standard functions in C++：
send(byval s as SOCKET, byval buf as const zstring ptr, byval len as long, byval flags as long) as long
recv(byval s as SOCKET, byval buf as zstring ptr, byval len as long, byval flags as long) as long

There's an old plugin for CE for doing basic packet stuff:

Would require being updated and such to latest. But should give you a start on what you want.
