Yes, there are two interfaces (/dev/ttyUSB2 and /dev/ttyUSB3) which answers 
"ok" to "at" and some other at-commands.

The classic serial-ppp-internet-connection works at least with /dev/ttyUSB2

I have to test /dev/ttyUSB3 if only "at" works or the whole ppp-stuff too.

I afraid if I create a working patch to a certain version, the version is very 
obsolete. Or you or the maintainers have extra work, because of a lot of 
beginner's mistakes.
My knowledge about c-programming and usb-driver-layouts is at a very low 
level.
What for "proper credit"? 
For adding some IDs?, while you and others wrote the whole driver, maintain 
version for version, find bugs and improve the smallest details?

That are your credits! 	 (seriously)

If you have time, please send me RFT-patches and the link to the version I 
have to apply them. 

This division of work was not wrong in past. 


Regards,

Thomas
