    make clean
    make all
    make inastall

    Avaj, then I have loged in as User, opened KPPP and dial.
    Then it says: "Unable to open modem". All settings are same, modem is in /dev/ but I can dial only in root user. HELP!!!!!!!

    Try this in a console **as root**:

    ln -f /dev/ttyS4 /dev/modem

    If that doesn't work, try the same thing except use /dev/ttyS0, 1, 2, or 3.

    unable to open modem

    After installing to my hard drive, all was well. Then I uninstalled a few packages I didn't need. The next time I tried to dial out I got the message, "unable to open modem." I found that the mode for /dev/ttyS0,1,and 2 had been reset to c _ _ _ _ _ _ _ _ _. I changed the mode back to crw-rw-rw-, and all was well again.
