+#PPP over Serial (PPPoS) client example
+
+This example uses the [pppos patches](https://github.com/amuzyka-grinn/esp-idf) proposed by amuzyka-grinn.
+
+Until those patches are not pulled to esp-idf, you must patch your esp-idf.
+
+##This is the required procedure:
+
+1. copy all files from patches directory to the root of your esp-idf
+2. go to esp-idf directory and execute 'apply_ppp_patch.sh'
+3. go back to this example directory
+4. as with other ESP32 examples, set IDF-PATH variable and add 'xtensa-esp32-elf/bin' to your path
+5. execute make menuconfig, enable PPP support (Component config → LWIP → Enable PPP support)
+6. execute make all to build the example
+7. execute make flash to flash the example
+
+##You can execute 'revert_ppp_patch.sh' in esp-idf to revert the changes before updating you esp-idf with 'git pull'
+
+
+It shows example of ppp client using lwip PPPoS api and GSM.
+
+Before you run this example, make sure your GSM is in command mode and is registered to network.
+
+Tested with GSM SIM800L.
