help
This driver uses the generic 3gpp AT commands, along
with the standard protocols CMUX and PPP, to configure
cellular modems to establish a point-to-point
network connection. It is a template for tailored
drivers for the ublox, quectel and other modems, which
include power management and more complex device specific
features.
