KPPP can't find the modem [SOLVED]

[mjtickner]

I am trying to use KPPP to control a modem 56k connection. My modem is located at /dev/ttySHCF0 but KPPP does not allow this location in it's options.

 

The config script which came with the modem drivers sets up /dev/modem to point to /dev/ttySHCF0 which KPPP can use. However, when I reboot /dev/modem is not present. I can regenerate the symbolic link, but I have to be running root privileges to do so.

 

Is there a way to either

 

a) stop the /dev/modem entry from being removed?

B) force KPPP to use /dev/ttySHCF0? or

c) modify an init script to add the link command?

 

Thanks.

 

Edit:

 

There seems to be a couple of way of doing this.

 

The first is that buried with the users .kde directory is a file called kppprc. The following entry should be present.

 

[Modem]
Device=/dev/modem

 

This can be edited to read /dev/ttySHCF0. Unfortunately this caused a "unable to create modem lock file" which I wasn't able to get around.

 

The second solution was provided by arvi on alt.os.linux.mandrake

 

if you know the tty name for your modem create small file in /etc/udev/rules.d/ (name does not matter but must end with .rules)

with contents like

 

{pts/2}% cat /etc/udev/rules.d/00-modem.rules

KERNEL="ttyS4" SYMLINK="modem"

 

Substituting the appropriate values, this works and the symlink is in place on boot with no lock file issues.
