TCP Protocol Implemementation Questions.

[Mondo]

I'm giving EO a try and I'd like to modify the code to suit some specific needs I want covered.

Could somebody explain to me how the TCP/IP communications of EO work. High level explanation is fine. Pointers to whitepapers describing how it works are cool too.

I'm trying to add some new methods, like to send a package from the server indicating the version number upon connection initialization, so that f the client version is older than te version number provided the automated upgrade process begins.

I've debugged the code all day, but I can't make or heads of it, besides its hard to debug for discrete TCP packages when so much is going around on the communications at once.

All help is greatly appreciated.
