    I'm currently working on building a simple token ring networking scheme
    over the parallel port (/dev/ppi0) for a graduate project. The project
    itself is to be used later for educational purposes, illustrating how you
    can build a network from the ground up through hardware developement,
    framing, and layering. The hardware is done, simple token managment is
    working, and data can be passed around the ring. So basically I have the
    physical and datalink layers mostly done. It's my understanding that if I
    can get my program to speak IP to FreeBSD (through a kernel module or
    something else) I could inherit its TCP/IP stack.

    Ideally I would like to have my simple token ring as another network
    device that could be used just like any other network interface. I've been
    reading through FreeBSD's handbooks and poking through /usr/src/sys/dev/.

    * Developers' Handbook:
    http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/index.html

    * FreeBSD Architecture Handbook (esp. Section II: Device Drivers):
    http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/index.html

    Basically I think I'm just looking for some guidance. Am I on the right
    track? or am I confused? I haven't had the best luck with google, so any
    other reading material would be greatly appreciated.

    Erik

I assumed this was an error and replaced it so that the ethernet linked-devices could exchange data with the token ring devices, but with hindsight, the "error" might have been intentional -- an attempt to psoe this very question and test knowledge of the difference between a gateway and a hub. ...
