This last "pppos_input[1]: got 14 bytes" is just the "NO CARRIER" from
the modem after it disconnects. This all happens almost instantly -
after switching to data mode all the following commands take less than
a second.
Seeing the first request from the modem (request for CHAP MD5
authorisation), I've also tried to enable "ANY" authorisation mode (or
just CHAP) and using "" both for user and password, but the behaviour
is mostly similar - the modem starts sending CHAP challenges, lwip
doesn't answer anything (I assume this is because the user and password
are empty, right?), and after some time the modem disconnects
("pppos_input[1]: got 14 bytes" == "NO CARRIER"). Here's the log:

Any ideas what am I doing wrong? There are just too many variables for
me to go further, as I'm not sure about anything here. Whether the AT
commands that I issue and their arguments are correct, I'm not sure
whether I should stick to "NONE" authentication or just keep using
"ANY" with empty user/password, maybe my lwipopts.h are wrong, and so
on and so on... So any help will be greatly appreciated!
Thanks in advance!
Regards,
FCh
