Hi!

quoted

"quite trivial" does not mix with ofono. I did parts and it is still
not finished. At the moment, I do not have enough working SIM cards to
test everything. Feel free to help :-).

I gave it a try but could only see "ofonod[14012]: motmdm init"
on start up. Running test/list-modems shows only /stktest
and no motmdm..

Do I need to configure something in /etc/ofono?

No, that should not be needed. But you need this:

user@devuan:~$ cat /etc/udev/rules.d/55-modem.rules
KERNEL=="ttyUSB4", ENV{OFONO_DRIVER}="g1"

KERNEL=="motmdm1", ENV{OFONO_DRIVER}="motmdm"

(different devices for different branches of ofono), and it is useful
to run ofono like this:

sudo OFONO_AT_DEBUG=1 src/ofonod -d -n -p motmdm,udevng,atmodem,motorolamodem

...to get right kind of debugging.

You then want to run enable-modem . online-modem is NOP, afaict.

Best regards,
