| Overview |
| ******** |
| |
| The generic GSM modem driver allows the user to connect Zephyr to a GSM modem |
| which provides a data connection to cellular operator's network. |
| The Zephyr uses :ref:`PPP (Point-to-Point Protocol) <ppp>` to connect |
| to the GSM modem using UART. Note that some cellular modems have proprietary |
| offloading support using AT commands, but usually those modems also support |
| 3GPP standards and provide PPP connection to them. |
| See :ref:`GSM modem sample application <gsm-modem-sample>` how to setup Zephyr |
| to use the GSM modem. |
| |
| The GSM muxing, that is defined in |
| `GSM 07.10 <https://www.etsi.org/deliver/etsi_ts/127000_127099/127010/15.00.00_60/ts_127010v150000p.pdf>`__, |
| and which allows mixing of AT commands and PPP traffic, is also supported in |
| this version of Zephyr. One needs to enable :kconfig:`CONFIG_GSM_MUX` and |
| :kconfig:`CONFIG_UART_MUX` configuration options to enable muxing. |
