The esp-modem component is a managed component for esp-idf that is used for communication with GSM/LTE modems
that support AT commands and PPP protocol as a network interface.
Get started with one of the examples:
* examples/pppos_client -- simple client implemented in C
* examples/modem_console -- C++ example implementing simple terminal console with DCE commands
* examples/ap_to_pppos -- this example focuses on the network connectivity of the esp-modem and provides a WiFi AP
that forwards packets (and uses NAT) to and from the PPPoS connection.
* examples/simple_cmux_client -- this example sets up the CMUX mode to talk to the modem using AT commands
with simultaneously maintaining active network connection.
