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?

Echo is coming back from the tower, which means communication between (...) (24 years ago, 4-Nov-00, to lugnet.robotics.rcx.nqc)
