Hi, I wonder if anyone can help. I am an electronic engineering student at the University of Birmingham and am attempting to implement IP on a PIC for my final year project. I am using MicroChip AppNote 724 ("Using PICmicro MCUs to connect to the Internet via PPP") and have converted this to use a seriallink to my NT server (running RAS) rather than a modem. The connection reaches state 7 which is the final PPP negotiation and then the PC times out as it fails to finish negotiations on the CCP compression protocol. The code also gives CRC errors. I have made an alteration to allow the negotiation of autentication protocols but apart from that and the changes to allow serial access, the code remains unchanged. Has anyone implemented this appnote. Please, if you have any ideas then let me know. Thanks for your time Chris Laws C.J.Laws@eee-fs4.bham.ac.uk
