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. chuck@xxxxxxxx said: > put "ln -s /dev/modem /dev/ttyS0" at the bottom of your /etc/rc.d/rc.local. > (did ^ ^ I get that right?) 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. Now david@xxxxxxxxxxxxx said: w/o copying the list > This sounds like it may be a udev problem.
