serial communication between Amiga and PC

I'm trying to set up a nullmodem connection between my A500+ and my Linux PC. I've built a cable with this wiring:

I've double checked the cable with an electronic contact-checker and the wiring is according to the image's numbers.

Then i had set up the Amiga with the following values
Code:
baud=9600
buffer=512
handshake=RTS/CTS
parity=none
rbits=8
wbits=8
stopbits=1
Then ran the following command on Linux:
Code:
stty 9600 -parenb cs8 crtscts -ixon -ixoff raw iutf8 -F /dev/ttyS0
Then i run a shell on both the Amiga and the Linux and gave this command
Type SER:
on the Amiga and this one on Linux
cat sertest.txt > /dev/ttyS0
but nothing happened. The Amiga keeps waiting forever, the Linux gave back the prompt after a while.

Anybody has any idea, what could go wrong?
