The PC is "in the loop" since if you powered it down it the system wouldn't work. In this case the PC is acting as a router and ethernet-to-SLIP adapter. My point was why not connect the PIC directly to the ethernet since this removes any dependence on the PC and would be easier to accomplish (in my opinion)? ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
