I have installed free driver from linuxant for my connexant 56K modem. After successful installation, I tried to make the modem connection by using kppp tool in fedora 5. when i query the modem , an error invoked "unable to create the modem lock file". Please help.

Tried to run it with higher privileges? If you don't have write access to where ever it tries to create the lockfile (an empty file usually), that's the problem..

I am facing a similar problem with RHEL 4? How do I find the location where the lock file will be created?

And I don't think I can go any further higher than the root user for the priveleges :-). I got the "unable to create lock file" when I tried querying the modem fom my root user account via kppp.

Anyone?

Hi,

I don't really know what exactly caused the file lock problem, but having edited the file /etc/ppp/options as:
lock
crtscts
defaultroute
noauth

and after subsequent reboots the problem was solved. Also, I found out that the link /dev/modem pointing to my internal modem /dev/ttySFSH0 was getting deleted everytime I rebooted. So I added the line,

ln -s /dev/ttySFSH0 dev/modem

to the /etc/rc.d/rc.local file and cleared that hurdle.
