  Listening to IR via NQC
 
I know that NQC can send IR messages; can it -- or any other command-line program -- listen to the IR port and dump any incoming messages to a file (or stdout)? (25 years ago, 23-Sep-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)
 
  Re: Listening to IR via NQC
 
(...) If I understand you correctly, then this is more difficult than it sounds, because the IR tower shuts down after a few seconds after the PC stops transmitting. Things work fine if the PC initiates a conversation (e.g. by asking the RCX to send (...) (25 years ago, 23-Sep-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

(...) Yes, that is what I'm looking for. Unless anyone else knows of anything, I guess it's time to dive into the coding. :) (...) Yeah, that would work great. Does anyone have code that does this?

  Re: Listening to IR via NQC
 
(...) You can sometimes fake it by sending "bad" codes in -raw mode with verbose mode turned on (-v) and a long timeout (-t). For example, to examine the Lego remote codes I kept typing this: nqc -v -t 2000 -raw 10 Since I didn't have an RCX around (...)

(...) Cool, that'd be great. What I'm looking for is: nqc -listen and then all IR messages sent by the RCX via SendMessage would get dumped, one per line, in decimal, to stdout. Additional parameters could make the format be comma-delimited, (...) (25 years ago, 24-Sep-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

(...) FWIW, I did something similar to this using NQC and the Datalog. It uses variable0 for polling and letting the PC know the Datalog has some "stuff" it wants to send. (URL) (25 years ago, 28-Sep-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)
