Previously, it was expected that the modem would immediately disconnect and close the PPP link, when the network was lost (+CEREG: 4 is received). Failure to do so, would result in modem attempting to chat with dlci2 channel, where as cellular modem driver would drop to dlci1. This would show as dial script timing out, which would freeze cellular modem driver. Adding dormant state enables graceful disconnection of PPP-link when the network is lost. This allows the modems which do not automatically close with network link loss to close based on PPP link closure. Signed-off-by: Markus Lassila <markus.lassila@nordicsemi.no>

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.
