Hi All. I am sorry upfront if this might seem like a stupid question. I am wanting to have some insight on how a modem plugs into the linux-kernel at architecture level.
First a bit of history. I have prior experience of using an onboard-modem on a ubuntu, via support from modem-manager. There, after the modem was (successfully) set up via "mmcli", the "wwan" interface started showing in "ifconfig", which then presented itself to be used just like any other wifi/ethernet listings in "ifconfig". Now, we are in a bit of situation, where only the AT-interface (of the modem) might be available to us (via a serial /dev/tty interface). Also, using AT-commands to actually set up sockets is also fine. Now, my query is once the AT-commands succesfully set up a socket, how does that link to "wwan" interface in "ifconfig" listings. Will be grateful to have the experts throw some light on this. Thanks and Regards, Ajay
