Does any one have any documentation on TCP/IP, in a form that is complete though concise.

At one time I had all the UDP, TCP, IP, etc... documentation in a form that was concise and easy to comprehend. Now when I search for this information I can not seem to find anything that is complete enough to be useful, or if it is complete it is a huge 400 page plus doc that would take a week of reading and flipping back and forth to get anything useful from.

I must apologize if this is a duplicate topic. As usual 0 results from searching the forum for terms containing less than 4 characters.

    You may want to look in the Spinneret forums you may find something there.

    Thank you bsnut.

    I could not find anything in the spinneret forums. I really want to write my own stack, and driver; though if I can not get the docs I guess that I can use the Spinneret code from the OBEX. Note this is for a project not related to spinneret.

    Does the spinneret code include everything for client side?

    If you want to roll your own TCP/IP stack, the Spinneret is not the place to look, since the onboard W5100 chip handles that detail internally. Search the forum for "ybox2", and you're likely to come across some useful info.

    Thank you for suggestions. I am still unable to find anything in the forums that is helpful.

    Does some have info on the various packet formats needed, by value offset, and rules for fields that the offset varies? Even with minimal explanation of each field would be very helpful, as this more a refresher for me than a new subj.

    I do intend to use the W5100 in raw ethernet mode, with my own stack, because the built in TCP/IP is to limited.

    Look here for Harrison's work: http://obex.parallax.com/objects/196/

    Not much memory left after loading the tcp/ip objects, but it is usable for small things. I was able to serve web pages from an SD card with his code before.

    Thank you. I will have to study this for a bit, but it may indeed provide the needed information. Again thank you.

    Thank you very much. This definitely contains the information I am looking for in driver_socket.spin. It will probably take me a couple hours to turn this into a reference for my work, though that Is a lot better than spending a couple of weeks sifting it from a TCP/IP document.
