Fine-grained socket connect

[Haden]

I need quite specific function for tcp/ip sockets: control of sending SYN, receiving ACK-SYN, and sending ACK as three, separate functions.
This could be done with RAW sockets, but I don't want to implement whole tcp infrastructure, send/recv are sufficient.

Maybe someone tried this? Some sort of RAW socket "transform" to SOCK_STREAM after doing handshake manually?
