I've developed an LDCC protocol stack for lejOS. Well, 1/4 of it. It's currently receive-only and only on the RCX platform.

Hi everyone, I did take a look at LNP, but I need to be sure that the RCX received the packet. As far as I Know, LNP is an UDP kind of communication. LLC is more reliable way to communicate as it uses ACK. I’m thinking know in recompile the RCXPort (...) (23 years ago, 7-Oct-03, to lugnet.robotics.rcx.java)

What I would do is give each RCX an internal "name" -- an identifier. When you send a message from the PC, the first part is the identifier.
