Sorry. if I am wrong, I am not very well experienced with the required access
rights. The background of my report is, that I tried to start the application
"umtsmon" (a dialout application for 3g-modems) as a normal user, and I found
no way to start it as no one else as root. The main problem is: It MUST be
started as root, as /dev/ppp has to be accessed by root. In other words: If
you start umtsmon as user root, everything is working fine, if you start it as
a normal user (which should be able to), it crashes because it cannot get
access to /dev/ppp.

This is very fine, so everything is in one hand and I hope, if I have
questions, I may ask them, even if they are dump. Please be gentle...
I will check the situation and maybe find another way.
