/dev/modem disappears at reboot

[dishawjp]

Hi All,

OK, got another head scratcher. I finally got my modem up and running in FC3. I can connect to my ISP and use minicom to connect to my devices at work and everything is fine... except... At each reboot, my sym link (ln -s /dev/modem /dev/ttyS0) is lost and needs to be recreated.

How do I set this so that I don't need to reset it at each reboot? The file /dev/modem is lost every time I reboot. This is another porblem I never saw before. In the past, setting up a sym link was a permanent situation unless specifically deleted. A ls -l on the file is:

Code: Select all

[root@eunix dev]# ls -l modem
lrwxrwxrwx  1 root root 10 Dec 30 18:12 modem -> /dev/ttyS0
[root@eunix dev]#


but if I reboot, it's gone.

if it was me, i'd put "ln -s /dev/modem /dev/ttyS0" somewhere in a script that i know will be run at boot time, but i am sure there will be a cleverer way to do it than that.

I was thinking that as a worst case, I could put something in my /etc/profile. But there has to be something strange going on if it's deleted every time I boot. It's not even a terrible problem, just one more weird thing with my system.

It probably has to do with udev. Is your udev package up to date? Worst case is you could copy your link to /etc/udev/devices (cp -a /dev/modem /etc/udev/devices).

Doh! I should have thought of that. I had to do that with the /dev/nvidia* files.

Thanks, that did it!
