(...) It's funny that you should bring this up - I've had exactly the same problems with several RCX's and downloading firmware from BrixCC.

Hi all, I am currently attending to a lecture in real time system on my university and we were assigned the homework to do exception handling in C on the RCX using setjmp and longjmp.
