Thanks for this !! Looks very promising !!
Seems that USB support for modems is being kept up-to-date in Linux, as the usb modem driver source code is present in linux 3.16 kernel (used by debian 8):
drivers/usb/class/cdc-acm.c drivers/usb/class/cdc-acm.h
Also, I see a web page with a Linux patch notice dated 17 November 2014 "[3.16.y-ckt,stable] Patch "USB: cdc-acm: add quirk for control-line state requests" has been added to staging queue".
Now that I think on it, didn't you mention earlier on this thread, getting access to a mobile device (cell phone?) modem from Linux?
Using Google, I found lots of documentation on getting USB modems to work on Linux (including the PPP stuff for the dial-up Internet link).
So I will try a USRobotics USR5637 56K V.92 USB modem.
That should work as far as I can tell. I still think getting dialup working with linux is a waste of time and money if you plan to go to DSL soon anyhow. -- Len Sorensen
