Summary
The command set consists of a series of short text strings which can be combined to produce commands for operations such as dialing, managing SMS functions, and changing the parameters of the connection. Many of the commands that are used to control wired dial-up modems, such as ATD (Dial), ATA (Answer), ATH (Hook control) and ATO (Return to online data state), are also supported by GSM/GPRS modems and mobile phones. This section is an overview of some AT commands that can be used with RUT routers.
gsmctl commands
gsmctl is a set of shell commands that can request information from or perform operations on a modem. In other words, gsmctl is a way to use AT commands in shell form.
-p, --ip <INTERFACE> Get IP of logical interface -e, --bsent <INTERFACE> Get number of bytes sent -r, --brecv <INTERFACE> Get number of bytes recieved -j, --connstate Get 3G connection state
AT command usage
To use a specific AT command via SSH, you can use the gsmctl -H. After this your console will enter shell mode where you can then just type AT commands in their regular format. Or you can use gsmctl -A <AT_COMMAND> to execute AT commands one at a time.
