I have no problem connecting without the "dial-on-demand" option set.
Neither do I use any chat script that I defined. I have attached a short
log showing that pppd refuses to use the demand option without some kind
of a connect script, while without it it works without a problem. In
addition, if you take a look at the debug messages you can see that
there are various prompts coming back from Netvision. My scenario is one
in which I might not want to be connected to the ADSL line all the time,
and I would the connection to kick in only on demand.
