==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.

Or you can use ''gsmctl -A <AT_COMMAND>'' to execute AT commands one at a time. Continuing from the example above, lets say you want to find out the RSSI value. While there are quite a few commands that can be used to achieve this goal, lets use the '''AT+CSQ''' that is used when executing ''gsmctl -q'':
# gsmctl -A AT
