What is ModemManager?

ModemManager is a DBus-activated daemon which controls mobile broadband (2G/3G/4G) devices and connections. Whether built-in devices, USB dongles, bluetooth-paired telephones, or professional RS232/USB devices with external power supplies, ModemManager is able to prepare and configure the modems and setup connections with them.

1.x is the stable series of ModemManager using the improved /org/freedesktop/ModemManager1 interface.
