I've searched the IETF Internet-Drafts and IETF Working Groups but still
could not find any information about it.
It was described in RFC 1644 (by Bob Braden IIRC) and in W. Richard
Stevens' book, _TCP/IP Illustrated, Volume 3_. It is implemented (but
turned off by default for security reasons) in FreeBSD; I am not aware
of any other operating system which currently ships with it.
The API introduced by Bob Braden's patches to SunOS and carried
forward into FreeBSD has proved useful even where T/TCP is disabled.
