My small TCP/IP stack C library for DOS

If anybody wants to know how a functional TCP/IP can be written, I thought I'd share what I wrote. I actually made it for DOS to play with getting vintage machines online, but it could easily be used as the stack for some kind of new OS or similar.

This server: http://8088.rubbermallet.org:81 is running an HTTP server powered by my stack, and hosts the source code. 10 MHz baby!
