Hi Ram,

Your email is very well written and is specific, so I am reading it very 
carefully, but I am travelling so my response might be in pieces.

So far so good. But why did you not give the mknod command right after 
this, before configuring wvdial

Wonder why you need PPPD options. I don't with my ETS1201. But there is 
a spelling error above. Did you copy-paste? It should be crtscts.

I am currently using the above, but without any modifications to any 
/etc/modprobe.d/ . I did that because it might conflict. But no idea. I 
also tried everything else, but only the above (without any other 
modifications) works.

You did not look for ttyUSB0, you looked for something with ttyu*, which 
is different than ttyU*.

I have been using ETS1201 under Ubuntu 8.04 (64 bit) and earlier under 
Ubuntu 8.10 (32 bit) for months now. And in between I also used it under 
Kubuntu 8.10 for a short while. And I had no problems. I had problems 
only when I tinkered with the config as per advice by Onkar, and my 
internet connection stopped working. But I do think that that is a more 
correct way of doing, only that someone more knowledgeable than me has 
to figure out the exact method, I can not do that.

Warm regards
