(...) The interface is specifically datagram only. Dunno about packet reassembly; I doubt it as the philosophy is minimalism. The main advantage I see in it is the ability to change the degree of checking it does on your behalf to ensure packets (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) From what little I remember about the Lego protocol, here are some thoughts. *) On reception, some Lego packets may contain data which look like the beginning of a legOS native protocol frame. Most likely, the checksum would fail (once enough (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) Yes this will be a datagram only protocol for the time being. The LNP will allow us to do things like debugging and remote control. I have also invisioned something like a "shell" running on the legOS that you could either "telnet" in to or (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) Assuming packets without large internal gaps, we could employ a timeout to wait for a packet transmission of unknown protocol type to end. At 2400 bps with 8E1 (LEGO, isn't it?), one data byte has 11 bits, so a space of 1.5*11/2400 s should be (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) Hmm.. with a little hacking you could certainly detect logic errors. The main problem I think would be writing alternative C-Functions for the H8 assembler, which makes up legOS itself. You'd also need to create a simulator engine for legOS to (...) (25 years ago, 21-Apr-99, to lugnet.robotics.rcx.legos)
