It does not work. When rebooting or halting it says 'read file system only' 
when it reaches those lines.

Anyhow symlink /dev/modem is removed when booting or halting.

no, it's the other way around ln -s /dev/ttyS0 /dev/modem. Me too, I get it 
always wrong the first time around.

I had put it there alrady.

Guess he is right and the stuff he recommends is a little heavy for me. When 
booting I see that udev is started.
