Sorry! I've lost control of the email-threads, [being forced to use this
crap gmail - who WANT you to get lost, so they can push adverts in-yo-face].

I appreciate the difficulty, especially when you don't have an rPi
to test with. I want to re-post something that I've recently thought
hard about, which reduces the "search space":-
Debugging sequential processes [most computing jobs]:==============
After tearing out my guts, to go on-line with a 3G-dongle, I analysed why
it seemed so difficult.
It's because people who have done it don't know the underlying mechamism,
or that they just lazely say "doA, doB...."
The correct method, especially for a 'serial-event-process' is:
CONFIRM1, CONFIRM2, ....
There's no point in tuning for the station, until it's confirmed that the
'radio-is-switched-on'. For 3G-dongle do:-------------------
1= confirm that usb-dongle is detected by system; lsusb; demesg | tail, ..etc.
2= confirm that method to switch dongle from CDROM to modem works:
`eject <device>` usually suffices, else there's <mode-switch>
3= my dongle gives feedback via LEDs.
Only after the above stages have succeeded, need you go on to ppp ..etc.
Reading the <measured output from each stage, tells you where to connect
the pipe for the next stage>, and massively reduces the search-space.
