Hello, I am still waiting for my RIS 1.5 to arrive. I would like to try out some programs like NQC, but none of them work without spirit.ocx installed.

Hi Ralph, I just tried out to remove all EMITs from ACCEPT word, in order to eliminate back echo from RCX. It works good: less Frame Errors and Break Interrupts from comm port during the session.

Hi, I'm writing a Visual C++ program to control simultaneously 2 RCX (using Spirit.ocx). I'd need to know when a task is ended to start the download of a new task (I'd need a kind of TaskDone event).

The optimization was intentional (and quite a lot of work, actually). I know it breaks with multiple tasks, but I was more concerned with keeping the variable pool from being cluttered with temporaries. With only 32 vars to use, its quite easy to (...)
