I just bought an NE64 dev board and am currently in the process of trying to get to accept a dhcp address. I hacked apart the connecterapp and NE64_Vend_OpenTcp to try to make my own project. Please let me know what i am doing wrong here. Here is what i got so far:

* Description : This file contains main() for the Connector_App demo
* code for the MC9S12NE64.
* It does initializations and calls functions in the
* Connector_App.c application code. The Connector_App.c
* file contains code for IO communication and UDP
* protocol functions on the MC9S12NE64.
*
* *** NOTE: This project is for demonstration purposes only. It excludes
* portions of the complete OpenTCP Stack for other protocols,
* such as http, bootp, dns, etc. The complete version of this
* stack is also included in the MC9S12NE64 Resource CD.
*
* *** NOTE: All header files have been removed from the Connector_App.mcp
* project due to the 32-file limit of CodeWarrior Special
* Edition. However, all the header files are included in your
* working folder and can be viewed by highlighting it's name
* in a source file, right clicking, and choosing "Find and
* Open File..." You may also just type the name of the file
* in any source file and do this.
