Re: Crashes with 6600GT when changing konsole
You can try starting screen like this instead:
screen /dev/ttyS0 9600
which will explicitly set the speed. Also, try running this command on the system with the 6600GT:
echo "test" > /dev/ttyS0
you should see 'test' appear in your screen session on the other system. If you do not, then something basic in your setup isn't right.
