Hi oFono list,
This is the first time I'm patching oFono so please excuse me for
mistakes or misunderstandings.
I am trying to add support for Quectel EG912Y. This modem seems to be
compatible with Quectel EC200, so I'm taking advantage of the existing
code in oFono 1.33 to handle it. This modem maps to 3 ttys:
- ttyUSB0: Debug. Output only. (interface 02)
- ttyUSB1: AT commands. (interface 03)
- ttyUSB2: AT commands and PPP. (interface 04)
First, I edited udevng.c:

Now the modem *seems* to work, except when putting it online using
./test/online-modem because it immediately shuts down, but it's probably
a matter of power supply, so let's ignore that. The real issue is it
sometimes stops replying to AT commands, either during
./test/enable-modem or ./test/online-modem execution, causing timeouts,
as confirmed by exporting OFONO_AT_DEBUG=1. I also tried to replace
`g_at_syntax_new_gsmv1()` with `g_at_syntax_new_gsm_permissive()` to no
avail. Is that a known or common issue when adding support for new
modems that you can help me troubleshooting?
Kind regards,
Fabio.
