while setting up a 3G modem, I configured wvdial and had lots of trouble.
I copied the configuration from http://nvdd.info/1iNncLt into Nano
And I got error messages that there was no Dialer Section 3gconnect when using this config file.
From my early Linux experience many years ago, I remembered that this could be due to "white space issues" eg the ^M problem.
But I could not remember how to view the "white space characters"
In the end I manually deleted all the spaces and end of lines and replaced them by hand with the required character (space bar or enter key)
This did solve the problem.
What is the better way of correcting such problems?
How can one make it visible easier?
and how does one prevent it from happening?
