Communication with the RCX looks fine, but the RCX is refusing to change
the program. This is exactly what would happen if no firmware was
loaded. Are you sure you have firmware installed? With firmware, the
display will look like this "00.00 ! 1", while without it will be " ! 1"
(where ! is the icon for the person standing still).
You can get the firmware file (FIRM0309.LGO) off the Mindstorms CD-ROM,
or download new firmware from www.legomindstorms.com as part of their
RCX 2.0 SDK. You can then use NQC to download this firmware...
nqc -firmfast FIRM0309.LGO
nqc -firmware FIRM0309.LGO
the "firmfast" option works a lot faster, but is more likely to fail
when there's a moderate amount of intereference (sunlight, etc) and
certain other situations. Try -firmfast, and if it doesn't work, resort
to -firmware.
