Ethernet Initalizing a TCP connection - SYN, SYN-ACK

Can anyone show me where the TCP connection is initialized, e.g. where the SYN, ACK packets are exchanged in the source code and the very start of the TCP connection is initialized, I can't seem to find it.

Thanks

I am no expert on Arduino TCP, but judging by reading the code and the data sheet, it is handled on the W5100 chip itself.

would it be possible to manually re-create this with raw sockets?

Wiznet has a 70 page data sheet on the W5100 chip with a lot of info.
