Yes, you can. You will need to do two things for it to work properly. The first will be to set the COM port's settings properly. When Hyper Terminal is opened it will ask you to select an icon and to name the session. Enter in a name and select an icon. Once you press enter you will be able to then select the COM port you will be using. Once the COM port is selected you will be prompted to set the proper port settings.
The typical settings for an AVR are 9600 8N1 no flow control, meaning 9600 baud, 8-bit, no parity, one stop bit, and no flow control.
For a DVD player the typical settings are 9600 8E1 no flow control, meaning 9600 baud, 8-bit, even parity, one stop bit, and no flow control.
We always suggest you check the protocol document regardless as requirements for newer devices may change.
The second item that must be set is the echoing of characters locally. To do this click File, Properties, Settings, ASCII Setup.. and then check off the Echo Typed Character Locally box and click OK and OK again. We then recommend you save the session by clicking File and Save so that you can easily come back and initiate a communication session. By doing this you will be able to send the commands as a string or packet as required. Please note this control will work for units that do not have an auto broadcast feature (constant auto reply). If you have a unit with the auto broadcast feature, it may need to be turned off if possible to use Hyper Terminal for basic command testing.

Introduction
Microsoft Hyperterminal is one of the most commonly used terminal emulator programs. This document explains how to use some Hyperterminal features with Cisco routers.
Prerequisites
Requirements
There are no specific requirements for this document. Please install at least one language pack red alert 3 uprising.
Components Used
This document is not restricted to specific software and hardware versions.
The information in this document was created from the 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, make sure that you understand the potential impact of any command.
Conventions
For more information on document conventions, refer to the Cisco Technical Tips Conventions.
Use the Correct Terminal Settings
If you see junk characters in Hyperterminal, or if the router no longer accepts keystrokes, it can be a Hyperterminal settings issue. Your router normally uses the default settings.
For information on how to configure those settings in Hyperterminal, refer to Applying Correct Terminal Emulator Settings for Console Connections.
If the default settings do not produce better results, it is possible that your router is configured to use nonstandard settings. In order to verify this, try to connect at different speeds until you get a valid prompt.
If none of the speeds is successful, your router can be in router hang state. To resolve the problem, refer to Troubleshooting Router Hangs.
Capture Router Output
In order to capture the output of long show commands (for example, from the show tech-support command) or router debugs, you cannot simply use copy and paste. Instead, use the Capture Text option from your Hyperterminal as explained here:
Select Transfer from the menu bar on your Hyperterminal program, and choose the Capture Text option from the pull-down menu:
In dialog box that is displayed, create the name of the file you want to send to the engineer. Then click Start.
Enter the terminal length 0 command at the router# prompt.
The terminal length command allows the console to scroll, even if you do not press the space bar after every screen.
Note: For the show tech-support command, 'terminal length 0' is on by default.
Issue the commands the engineer has asked for, such as the show interfaces command.
When the command is completed, select the Stop option from the Capture Text sub menu.
Repeat steps 1 through 5 for as many text captures as you need. Simply attach your newly created files to an e-mail, and send them to your Cisco support representative.
Note: It is not necessary to set the terminal length to zero each time. The terminal length setting stays at zero until another value is set manually.
Enter the terminal length 24 command at the router# prompt. This causes the console to pause after each full screen, and allows you to read the output:
Send a Break Signal
In order to recover a password, or troubleshoot router hangs and booting issues, send a break signal to your router. For Hyperterminal, this is usually done with the CTRL-Break or CTRL-F6 Break sequence. For a list of additional possible key combinations, refer to Standard Break Key Sequence Combinations.
If the router does not accept the break key, carefully read the Troubleshooting Tips and How to Simulate a Break Key Sequence sections from the Standard Break Key Sequence Combinations document.
Send a Cisco IOS Software Image Through Hyperterminal Xmodem
If for some reason (for example, a boot failure) you need to install a Cisco IOS® software image through the console port, you can use Xmodem transfer. For detailed step-by-step instructions, refer to Xmodem Console Download Procedure Using ROMmon.
