Hi,
I recently bought an RIS kit and from my Windows box it works fine. When
I try using LinuxPPC off my PPC Amiga I get the following:
[root] /home/chris/nqc/nqc-2.2.r2 >bin/nqc -v -raw 10

No reply from RCX
This happens no matter the ambient illumination - sunlight, artificial tungsten
light, darkness - and the RCX is situated exactly 6 inches from the front of
the IR tower. The only differences here are the computer and OS - everything
else is the same. I've tried doing
stty -a </dev/ttyS0
when nqc is talking to the IR tower and it reports the baud is 2400, is that
correct (there's two different values in the source - 2400 and 9600).
Any suggestions?

| (...) Perhaps timing is a problem. Try: nqc -t 1000 -raw 10 This forces a longer (1 second) timeout per packet instead of the dynamic retry timing. Is the output any different? Echo is coming back from the tower, which means communication between (...) (24 years ago, 4-Nov-00, to lugnet.robotics.rcx.nqc)
