I think there were details discussed there that may or may not have amounted to a fairly specific proposal for a protocol for LegOS. Anybody care to summarize whatever was (...)

| | | | | With all of the talk about networking and IP embedding and such, and since I'm working on a proprietary '485 master/slave protocol for a client, I had to dust off a GREAT university text on networks. It devotes an entire chapter to ALOHA and slotted (...) (25 years ago, 1-May-99, to lugnet.robotics.rcx.legos, lugnet.robotics)

Just to state my interests: I'm mainly interested in the protocol, eg what level of service it would provide etc. In particular, I'm interested in layering a higher level gauranteed delivery protocol atop whatever simple one is provided.
