"ln -sf /dev/ttys4 /dev/modem
I su went into root & put the above command in a terminal window KPPP still does not see the modem Get "uable to open modem" Is there a way to manually put the choice of /dev/ttyS4 in KPPP ?"
If that isn't a typo then there is a capitalization problem here. The device is /dev/ttyS4. There is a /dev/ttys4 but it is not a modem and for sure is not COM5.
ln -s /dev/ttyS4 /dev/modem
Also check /dev/ttyS4 permissions:
ls -l /dev/ttyS4
If you want a user to be able to start kppp then /dev/ttyS4 should have permissions of rwxrwxrwx
Be prepared. Create a LifeBoat CD.
