Hi,

I'v recently add support for ge910 quad,
(https://github.com/p1ng0o/ofono/commits/ovk) and I had some ugly issues.

1/ doesn't support proper atmux
(https://github.com/p1ng0o/ofono/commit/1b7f64b2faaca91ce711774a12ba79ad35c=
bb8ed)

Quote from support(a)telit:

"In Telit implementation module is NEVER an initiator since it is up to
controller to send the
SABM command to DLCI 0
* Module is ALWAYS a responder
* Module send the V24 frame as F9 01 EF 09 E3 05 0B 8D 9A F9 where C/R
bit is set to 1
* According to Table 1 this is a response frame
* According to above DTE don=E2=80=99t have to copy the status."

thread with denis,

2/ Ugly init process, forced me to create plugin from scratch
(https://github.com/p1ng0o/ofono/commit/6534001cd5801a30b0c237b697226ed2d02=
fe774)

- I have to wait QSS=3D2 for initialize all devices, sometimes it take
more than modem powered timeout !

- Sometime I didn't receive QSS notification at all

Quote from support(a)telit:

"just try to increase the waiting time for QSS answer (also 1 minute at
the beginning: it depends also on the number of records in the SIM
phonebook, ecc.)"

Did you face same issues ?
