(...) Boy, this RCX to Spy IR comm thing is sure going the right way! The SPYBOTICS are a little known and hidden LEGO gem. Gramps Eddie & Grandson CJ (20 years ago, 26-Mar-04, to lugnet.robotics.spybotics, lugnet.robotics, lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

I'm a little surprised that the Spybot doesn't need to see the packet header byte - the byte containing the range/orientation bits preceding the 0x8n Ping byte. The header is deliberately generated with the stop bit cleared to force a framing error. (...)

(...) Yes, that is what another person told me via email yesterday. So a ping simulation function for an RCX running the RCX2 firmware could be: // nLinkID = 0-7, where 0 = no link, 7 = pc link, 1-6 = controller link // nMyID = 8-255 (minBotID = 8, (...)
