As for libraries, I'm not sure what qualifies as "cute", but within NQC,
all of the RCX communication is containd within its own set of classes
(which I call rcxlib).  Compile and link against these classes to add RCX
functionality to your own C++ programs.  The access is robust, but not
"high level".  For example, there isn't a method to turn on a motor.

Thanks for the explanation. So, it's back to the basics! ;-)

I did not explain my question very well, I think. 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

(...) 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)
