* Note: Socket_open does not actually open socket on all drivers, but that's deferred until calling `sendto`.
* The reason is that IP stack implementations are very much modem specific and it's quite common that when a
* socket is created (via AT commands) it must also be given remote IP address, and that is usually known
* only when calling `sendto`.
