-Go to **Setup -> Registers -> Tools -> Custom Protocols** and add this protocol.

After that you can create connection using this protocol. Some modems could answer on AT commands with huge delays. You might need specify extremely long timeouts for them in connection settings (3-6 seconds!) in you will see such behavior.
  
 Please note that modern modems usually have multiple UARTs (/dev/ttyUSB0, /dev/ttyUSB1, /dev/ttyUSB2, etc). Some of these UARTs can be used for data exchange only, another - for control modem during the established call. You have to find such control port manually (basically, try one by one) to find port that will react on AT-commands and use this post in this custom protocol. Please note that modern modems usually have multiple UARTs (/dev/ttyUSB0, /dev/ttyUSB1, /dev/ttyUSB2, etc).
