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:

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).

Did you set the correct permissions for the serial ports (normally they're
only accessible by root under Linux) Do a chmod 777 for /dev/ttyS0

(...) Umm.. note the prompt ;)) I'd done an su root before testing to avoid permissions problems. This seems like a problem with nqc on LinuxPPC 3Q99, but I can't understand quite what it is as the tower obviously works - the green light is visible (...)
