Tera Term is a useful application, which allows the connection to any remote Telnet or SSH hosts. It sports a clean and crisp layout that is easy to work with. The application does not take a long time to wrap your head around and is also very light on system resources. From the Windows computer, download and install Tera Term. Launch Tera Term. From the New Connection window, select Serial and then select the Port on your computer that is connected to the router. Press the Enter key and verify that the router responds. If you are prompted for a username/password, login as admin/C1sco1234. Cisco is the worldwide leader in IT, networking, and cybersecurity solutions. We help companies of all sizes transform how people connect, communicate, and collaborate. Can't get keystrokes from putty or tera term in order to config cisco switch and router.

Tera Term is easily one of the most powerful free Terminal Emulation Software that I have come across and the power of it lies in its scripting language TTL. Of-course, it is not as extensive and capability rich as Perl but for a non-programmer, a browse through a single help file on TTL language is all it takes to create wonderful scripts that could make his/her life easier in maintaining huge networks.The capabilities are limitless and if you could find better ways of enhancing the following script, please come forward and do your bit.
The purpose of the script is for terminal configuration of repetitive commands in multiple terminal enabled devices at once but sequentially without human intervention.
The other purpose of the script is to fetch terminal information from multiple terminal enabled devices at once but sequentially without human intervention.
The script is primarily designed for working with Cisco devices which can be configured using terminal emulation and which has a Command Line Interface (CLI ).
The execution of the script requires Tera Term Software installed on the user’s computer. The Tera Term software can be downloaded from the following URL:
http://hp.vector.co.jp/authors/VA002416/teraterm.html
The Procedure for execution of the script is as follows:
- Download Tera Term from the above mentioned URL.
- Unzip and downloaded file and execute the Setup.exe file.
- Install the Software in a specified destination.
- Copy the below provided script in the Tera Term directory.
- The script has an extension of .TTL and can be opened in notepad.
- Open the file in notepad and change the variable ‘dirname’ in the script to reflect your Tera Term Directory.
- Make two Text Files in the directory specified by the variable ‘dirname’ by the following names:
ip.txt
commands.txt
- Make sure you have telnet access to all the devices you would like to configure.
- Open the ip.txt file and enter the IP addresses of all the devices for which the configuration needs to be fetched or pushed. Place only one IP address per line.
- Open the commands.txt file and enter the commands for configuration or commands for fetching configuration from the devices. Please note that the commands need to be compatible on all the devices entered in the ip.txt file. Please put in the commands in sequential order as you would configure the device in the normal circumstances. For eg:
terminal length 0
show running-config
config t
enable secret cisco
![Teraterm cisco packet tracer Teraterm cisco packet tracer](/uploads/1/3/4/6/134684278/473526289.jpg)
exit
terminal length 24
write memory
- Please place the commands that are required after authentication is done. The script expects a device prompt (which can be customized easily) by default after authentication. You may change it at any point of time.
- Execute the file ttpmacro.exe present in the Tera Term directory and select the macro '.ttl’ extension.
- Please enter the Username for logging into the devices and press OK. Please note the Username and Password prompt would appear only once. The same username and password would be used to login into all the devices.
- Please enter the password in the Password Prompt Dialog Box and press OK.
- For Enable Password Authentication Prompt, click yes if you have enable password authentication configured in atleast some of the devices or click no if you don’t have enable password configured in any of the devices.
- If yes, then provide the enable password to log into all the devices. The password is assumed to be common on all the devices.
- For the Logging Dialog Box. Click yes if you want to log the output or click no if you don’t want to log the output.
- If yes, enter the directory in which the logs have to be placed. For eg: If the directory is ‘C:logs’ then enter it in the following format:
c:logs
- Please note that the ‘’ sign is important after you enter the directory path and name.
- Sit back and relax, as the commands entered in the commands.txt file is executed in every device entered in ip.txt.
P.S.: While fetching configuration from any device like that of Cisco, please make sure to keep the terminal length to zero so that the device prompt appears immediately after the execution of the command.
Please give your feedbacks to make it better.
Below is the script for use with Tera Term. Just copy & paste the below code in a notepad and save it with a TTL extension.

Cisco Teraterm Settings
Issue: Unable to copy IOS to Switch using USB or Telnet.
Reason: We faced issue regarding the switch always being booted in ROMMON mode , later on we came to know that our colleague accidentally deleted the IOS. Copying the IOS not a big issue but having no USB port or TFTP connection made the task difficult.
Solution: In case when no USB or TFTP connection available, we can use the XMODEM to transfer the IOS to Switch/Router. Just follow the below step:
Step 1: Open TERA TERM and boot the switch set the baud rate to higher value so to increase IOS transfer speed.
Teraterm Cisco Break Sequence
SET BAUD 115200
Change Tera term baud rate by going to setup->Serial port->115200.
Step 2: Enter command to copy IOS in Switch/Router.
![Cisco teraterm macro Cisco teraterm macro](/uploads/1/3/4/6/134684278/690433395.png)
copy xmodem:IOS.bin flash:IOS.bin
Press enter
Step 3: Go to File->Transfer->xmodem->send in tera term and select the IOS.bin file.
Teraterm Cisco Packet Tracer
Wait till the ios is copied to flash
Step 4: Enter command to check if IOS is copied to flash and reboot the router/Switch
Dir flash:
Boot flash:IOS.bin
Step5: After booting with IOS set baud back to 9600
