Does anyone know of a code sample to encode and decode an Ethernet LAN protocol. I will be writing such a routine over the next couple of days, If snipetts were available, I would be able to save much time, and spend more time with the family for Christmas.Help if you can..By the way MERRY CHRISTMAS to the Piclist and a very happy new (Y2K) Year. I hope Know body gets bit by the Y2K BUG....Gordon VarneyMy apologies, I should be more specific about what I am looking for.I have a data stream that is coming in on one I/O pin of a 16F876. I would like to encode the data stream into a Manchester codeing format simular to Ethernet LAN, send it over a 10 base T coax and decode it at the other end. No special hardware Just PIC to PIC.None of the Protocol jiberish just the raw Manchester code where as the data and a clock is sent to the other controller, and decoded with the data intact with a seperate clock output.Gordon Varney
