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 (...)

(...) 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)

Hi all! Having a touch of flu, I might be asking a FAQ here... if so, sorry. How can the RCX communicate with the PC, except by SendMessage? The Spirit.ocx has the Poll functionality to ask for RCX state - is there any similar stuff in NQC? And are (...) (25 years ago, 5-Nov-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)
