wvdial script with knoppix & easy setup for Indian datacards - one trouble though

[rajibando]

What is wrong with the script wv-connect.sh (originally compiled from various sources and posted in knoppix forum http://forums.debian.net/viewtopic.php?f=5&t=74246 ) that the modem is reinitialised after an incremental time period every time the system fails to connect to the internet?
Otherwise, the script is excellent to connect to the internet when the software provided by the service provider is only capable of operation in Windows.
The outputs are:
--> Auto Reconnect will be attempted in 5 seconds
--> Auto Reconnect will be attempted in 10 seconds
--> Auto Reconnect will be attempted in 20 seconds
............
and so on.
The script and the output files are attached.

I am extremely sorry, the word 'originally' should be ignored. I am _not_ the creator of the script.
And the 'knoppix forum' should be read as 'Debian forum'.
I once again apologise for the words used, had there been an option I would've edited the post.

Do you use the same modem as the author of the script ('Teracom device (Model no. LW273)')?
If this is not the case are the AT commands the right ones for your device?

[Capricorny]

If you are not sure the problem is Knoppix-specific, I suggest you ask for advice in more specialized fora. As is implied in klaus2008's answer, this might be a rather model-related issue, so this may be one of the less useful places to ask for advice..

yes, it works excellently. It is a 3G modem, but since my SIM card is 2G I can use the card in 2G speeds only. reports itself as HSPAdatacard.
The lsusb code in detailed mode produces the attached output.

This might still have little to do with Knoppix?
I was in a similar situation with a 4G mobile router/3G SIM card some weeks ago. Instability, frequent rebooting. Changed to 4G SIM card, problem solved.

My setup doesn't hang up frequently, works just fine!
I just wanted to learn where exactly in the code is the incremental time period is incorporated?
Recall:
--> Auto Reconnect will be attempted in 5 seconds
--> Auto Reconnect will be attempted in 10 seconds
--> Auto Reconnect will be attempted in 20 seconds
...........
and so on, i.e., a sequence of ar^n, where a=5, r=2, n=0,1,2,...,n
My question was how this happens, where in the script is this formulation given? Or is it with the wvdial code itself!

Oh, I didn't understand that. Sorry!

It has to be in the wvdial code, which can be inspected by installing Debian source packages, or similar downloads, like this one:
http://linux.softpedia.com/progDownload/WvDial-Download-10580.html

What happens in the script, is that a conf file for wvdial is generated from user provided parameters and defaults, and wvdial is then called with that configuration.

You had to go through the script wv-connect.sh. Please read the file carefully and then post. We have to understand that since our timezones are different, the redundant cycles of exchanges waste our time.
See particularly, the area EOT... and tmp file creation...

I told you, it is not in that script. OK?

Got it.
I can't read source codes, ... well, not very well.... Okay, will check and get back. I have posted an email to the Debian forum.
I have checked the aptitude information for wvdial and found an email-Id for the creator of wvdial, which is wvdial\-list@lists.nit.ca, but it bounced back. How do you interpret that email-Id.? I also posted to wvstreams-devel@googlegroups.com.
Let's see what transpires from our endeavours.
