/dev/modem link deleted at boot

jakubi · 01-30-2006, 09:14 PM

In Fedora Core 4 I have set as root the link

ln -s /dev/ttyS0 /dev/modem

to use my serial modem. It worked fine, but on the next boot in FC4
this link was no longer there. So, after every boot I have to set this link
again. Why is it deleted?

you probably need a newer driver.

The "problem" is udev, as stated in the similar threads below.
I have added the link command to /etc/rc.d/rc.local. That solved the problem.

On the other hand I have tried adding a new udev rule file, but did not work.

Although you might want to install a newer driver anyway...

This is an external serial modem. Thus, no driver is required. What do you mean by a new driver?

you may want to check this out, especially sec. 2.3

although 'normally' it is understood that external (serial) modems with linux do not need 'drivers' per say.. this seems to be more of a school-of-thought from the past.

linux STILL needs all the other software (drivers) necessary to both access and utilize newer type-- external/serial type modems.

good luck again, and let us know..
