Where can I find SQL*Net TCP/IP protocol documentaion

Hi,

I would like to know if there is a publicly available document that describes the SQL*Net TCP/IP protocol. Is this something that I can get from Oracle? What I'm looking for is a way to communicate with the Oracle listener (orasrv or the Oracle 7 equivalent) without having to use the SQL*Net software at the client workstation.

Information for both Oracle 6 and 7 listeners would be great.

Any help would be much appreciated.

Thanks...
Tom
