How To Configure Hyperterminal

Introduction

This document explains the correct settings to apply when you connect a PC to a router's console port. This document also details how to use the PC's Hyper Terminal to configure and monitor a router.

Prerequisites

Here is a screenshot of how to configure these settings on a Windows-based PC running Hyper Terminal: Without these settings, the router may display but does not accept any keystrokes. The router, therefore, appears as if it is hung or has crashed. With the correct settings, you can use Hyper Terminal to configure and monitor the router.

Requirements

There are no specific requirements for this document.

Components Used

This document is not restricted to specific software and hardware versions.

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command before you use it.

Background

When a console cable is connected from a PC's COM serial port to the router, a router prompt does not appear on the Hyper Terminal. Garbage characters appear on the Hyper Terminal, and the router no longer accepts keystrokes. It appears as if the router is hanging and is not responsive.

Solution

The settings in the Hyper Terminal need to be set correctly; otherwise, 'strange-looking' or garbage characters may show up on the screen. When you set up the connection, use these settings:

Without these settings, the router may display but does not accept any keystrokes. The router, therefore, appears as if it is hung or has crashed. With the correct settings, you can use Hyper Terminal to configure and monitor the router.

Note: On some routers the console speed has been changed in the configuration register, and a bits-per-second speed of 9600 does not work. However, this situation is not common. Valid speeds (other than 9600bps) include 1200, 2400, and 4800 bps. On some platforms, notably the 3600 Series Routers, 19200, 38400, 57600 and 115200 bps are supported. Try these if you fail to connect with the settings described in this document.

Console Session Not Accepting Key Strokes

This issue can be due to any of these reasons:

• Difference in baud rate and the bits per second value

• Bad console cable

• Scroll lock option is enabled on the keyboard (make sure that the scroll lock key is disabled on the Keyboard)

Most routers have a serial port used to connect to the serial port of your computer. Using Windows HyperTerminal, you can connect to the router and enter the commands necessary to set up the router on your network. When you connect to the router, the first prompt shown is the login prompt. Use the login that you originally set up when you installed the router to manage its services.

1.

Connect your computer to the router using the serial cable. Connect one side of the cable to your computer's serial port and the other side to the router's serial port.

2.

Open the HyperTerminal software in the Windows 'Accessories' program group. When you open the software, a connection window displays.

3.

Type 'Router' in the connection name text box. Select 'COM1' from the drop-down box. Change the baud rate to '9600' in the next configuration window and click 'OK' to connect to your router.

4.

Type your username and password to connect to the router's configuration console. Press 'Enter' to log in.
