You're trying this still with standard hardware and standard dll-src,
right? Otherwise, check that you use the right baud-rate and parity
settings (4800, no parity bit, 1 start, 1 stop bit).
In my experience the IR-communication doesn't work that well,
especially in 4800 baud mode. It is mainly the PC that does not
understand the RCX correctly. Try running dll-src with "-v" to get
more information. Sometimes the PC receives part of the reply but
there are some broken or missing bytes so the reply is just ignored.
I think LNP_FAST mode is not tested very often. There may also be a
stupid bug in brickOS code that prevents communication.
