− | '''''gsmctl''''' is an SSH command used to communicate with a RUTxxx router's modem. In other words, ''gsmctl'' relays '''AT''' commands (a set of instructions used to control a modem) to the router's modem; thus, providing the user with a way to control and obtain information from the modem via SSH. This can be used to either obtain certain modem related variables (current signal strength, operator, connection state, etc.) or to execute certain actions (sending SMS messages, changing the frequency band in use, etc.).
