the question is:
I installed red hat 8.0, I have an isdn ta (zyxel omni net lcd+) and I'd like to connect to the internet with it.
Using the System setting - Network menu, if I trying to make a connection I see my isdn ta is not listed (actually, most of popular ta's is are not there).
I tried to create a connection using my isdn ta as a modem, I tried to make it active (with no hope) and...surprise!!! It worked!!
Now I wonder: is it safe? may I have to use a ppp script instead? I note the system crashed once or twice: do you think it could be related to this "strange" network setting?

Thanks very much.
