Hi, I am currently searching for a method to use an Ethernet interfaces as a backup route to a primary Cellular connection. The catch is that the FastEthernet port needs to enabled/disabled based on Cellular signal strength. Alternatively the Ethernet device attached to the FE has the ability to receive AT commands for connection control. This may be possible with TCL or other methods. If anyone can assist either options or source of TCL information, this will be greatly appreciated.
