What I would like to do is to steer the RCX from the PC, by querying its state and send it high-level commands (for example to make another maze-walker-thingie). It can be done wirh SendMessage, but it would be much nicer to be able to send more than a byte at a time... I decided to try to solve this with the original firmware first, before going to legOS or pbForth (with which I could probably have all the software on the RCX, and not need any communication except maybe for progress reports or such) Thanks again /Vlad

		Re: Communication with PC using NQC
(...) Could you be more specific on "querying its state" and "high-level commands"? If you're willing to write custom C++ code, you can pretty much do whatever you want on top of the rcxlib stuff from the NQC source base. Its pretty easy to send (...)

(...) You can use the -raw option for nqc to send raw commands (including the poll command) to the RCX. Not pretty, but it works in a pinch. As for libraries, I'm not sure what qualifies as "cute", but within NQC, all of the RCX communication is (...) (25 years ago, 6-Nov-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)
