Access to the Internet via GPRS is provided via PPP using the [https://linux.die.net/man/8/pppd pppd] service. For its operation, you need to create a configuration file that corresponds to the settings of your operator. Configuration files for the "big three" rusian operators are pre-installed in the standard image. The files are stored in the /etc/ppp/peers and /etc/chatscripts directories. For other operators or special APNs, create your configuration files based on standard ones. To do this, use the '''pppconfig''' utility (installed with '''apt-get install pppconfig''') to create a connection configuration file with parameters for your operator (for example, MTS). You can also count on the [https://help.ubuntu.com/community/DialupModemHowto/SetUpDialer#Alternative_Way_2_.28using_pppconfig_.26_pon.2Fpoff.29 instructions]. Note the ''115200 nocrtsct settings'' that must be present in the configuration files. | Access to the Internet via GPRS is provided via PPP using the [https://linux.die.net/man/8/pppd pppd] service.

If you connect to the Internet via 3G, you should replace the UART port (/dev/ttyGSM (or /dev/ttyAPP0 in older controller models)) with the CDC-ACM port (/dev/ttyACM0) in the configuration file for your operator. This is necessary to ensure that the communication speed is not limited to the modem UART port bandwidth: | |||
