I read the document sent by @mlw (thank you again, it really helped me to more understand how a modem works with an OS). Unfortunately it seems I have an issue on the hardware detection of the modem. Maybe I need to install a driver or something like that to help OpenWRT to take the device into account but I don’t know how to go with this …
** Maybe someone can point me to the correct procedure to be able to have the modem ready (as a reminder, at the end, what I will need is a bridge between the EM7565 and the on board Wi-Fi modem so I need a modem “ready” for the bridge adventure which will arrive next)? **
To precise the context, here are the commands I ran and their results:

^C means that I needed to kill the process because it was not responding, even after a long time).
