Note: If you use a USB to Serial adapter to establish a connection to the router, remember to verify what COM port is given to the USB adapter and select the appropriate COM number under the terminal emulator settings. Here is an example of how to configure these settings on PuTTY Terminal Emulator: Here is an example of how to configure these settings on a Windows-based PC with Hyper Terminal: When you set up the connection, use these settings: Bits per sec : 9600 The settings in the Terminal Emulator software need to be set correctly otherwise, unintelligible characters show up on the screen. It appears as if the router has crashed or is not responsive.

Another symptom that can be observed is that garbage characters appear on the Terminal Emulator software, and the router no longer accepts keystrokes. When a console cable is connected from a PC COM serial port or from a USB to Serial adapter to the router console port, a router prompt does not appear on the Terminal Emulator.
