testing new Modem modem-v1.0.3 on a SIMCOM A7672E with USB (IDFGH-11308)

          Just check the examples.

This would create the corresponding DTE with these two terminals already included:

The rest is the exactly same (one DTE, one DCE, one network interface).

---

PS: This constructs a DTE which simply takes two terminals, and sets the mode to DUAL_MODE so no further switching is necessary.

so, made a github here: https://github.com/diplfranzhoepfinger/esp-protocols-tree-master-components-esp_modem-examples-pppos_client/tree/feature/USB-Modem

and a log here: https://gist.github.com/diplfranzhoepfinger/0a3c1c1921502d753910e54c7af1fdc7

strange thing: AT+CSQ

is replied by

+CSQ: 99,99

but we get a

E (22361) pppos_example: esp_modem_get_signal_quality failed with -1 ESP_FAIL

@diplfranzhoepfinger Did you include the fix I mentioned in https://github.com/espressif/esp-protocols/issues/375#issuecomment-1772525793 ?

Just merged it yesterday; and added a new CI runner, which runs this example (S2+A7670E) https://github.com/espressif/esp-protocols/actions/runs/6628377154/job/18006092226#step:5:161 with this config:

With your mentioned patch it works perfect in INFO Logging Mode:
