From Tera Term. To start MACRO (TTL), select the Control Macro command and then the macro file in the Open Macro dialog box. The question is how to write command inside batch file, to call macro file and run automatically by just opening batch file. TeraTerm communicates through a serial port (COM4) on the host computer. (In the case of the PC, COM4 is physically located on the back of the unit.) An RS232C serial cable is connected to the COM port connector on the back of the computer. At the end of the cable that connects to COM4 is a 25-pin connector (DB25P). No Serial connection with Tera Term. Hi, I just downloaded Tera Term to my computer and I am trying to set my 'new connection' to serial for the mbed serial port. However, the serial option is grayed out. I tried updating the firmware on the mbed but it hasn't helped. I also tried updating the driver in the device manager. Any suggestions? Once you have set your serial terminal to the correct baude rate (via 'Setup-Serial') on COM1 (via 'Setup-General-Default Port'), you can save the setup via 'Setup-Save Setup.' Save this setup in the TeraTerm Installation directory by overwriting TERATERM.INI.

Introduction[edit]

Tera Term is an opensource terminal emulator on MS-Windows commonly used by us developers. Tera Term supports a 'rich' macro language that can help in automating user actions. These scripts usually remain personal - rarely shared.

In this page, I intend to share the basic scripts that can be used to automate common tasks in the Linux PSP release. The scripts were created with intentional hierarchy to maximize reuse (via inclusion) and minimize redundancy across scripts. Currently, these scripts apply to OMAP35x Linux PSP. But, can be extended easily to other platforms.

Needless to say, these scripts are open to enhancements.

How to execute a TeraTerm script?[edit]

Scripts[edit]

File Naming Conventions[edit]

• A file containing common macros - that can be included in other scripts - is prefixed with double underscore e.g. __common.ttl
• The purpose / functionality of the file can be indicated after a '-' (minus) in the file name e.g. __uboot-config.ttl
• Name of the container script that you execute is prefixed with name of the board e.g. omap3evm-boot-ramdisk.ttl.

What about DaVinci TeraTerm Scripts?[edit]

Below are a few simple scripts used to boot a DaVinci EVM - obviously you'll need to modify your IP address, kernel name and rootpath appropriately. These examples should serve as a good starting point if you want to create your own scripts.

To run the scripts, simply hit any key during the U-boot countdown to get to the U-boot prompt. Then run 'Macro->Control' and browse to the *.ttl.

DM6446: Crossover Script[edit]

When you don't have a switch/router and need to boot your EVM using TFTP/NFS, you can directly connect your EVM to your laptop with a crossover cable. Here, the Linux host's IP address is set to 192.168.1.100 (modify as needed). To manually set the Linux host's IP address:

1. host$ su - Login as root
2. host# setup - Setup your network
3. Browse to Network Configuration, then choose 'Yes' (to Setup Network)
4. Uncheck 'Use dynamic IP configuration' using the spacebar (if needed)
5. Tab to 'IP address:' and type 192.168.1.100 and tab (using default values for Netmask, Gateway and Nameserver) to 'OK' and hit Enter. Save your settings when prompted.
6. host# /etc/init.d/network restart - Restart your network
7. host# ipconfig - Verify that your IP address has been set to 192.168.1.100

Also, note the $(videoargs) setting below (setup for DVSDK 1.30)--if you are using an older DVSDK, simply remove $(videoargs) from the bootargs.

What about OMAP-L1 TeraTerm Scripts?[edit]

Are there any OMAPL137 examples?[edit]

Below is an example ttl script for users with a switch/router and NFS server. To reiterate one of the advantages of using a ttl script is that you can share boards between team members without wrenching their boot settings.

This ttl script has been tested in the SDK 1.00.00.10 environment and all directories and filenames match the default installation procedure as listed in the Installing the Software for OMAP-L137

Note: for OMAPL137 you must set the delay as mentioned in the What is a TeraTerm INI? section

• Replace the serverip with whatever /sbin/ifconfig shows as your IP address.
• Replace the useracct with the name you use to login to your Linux PC.

The script below works with an USB pendrive that should meet the requirements below. Check the <LSP_02.20_OMAP-L137_User_Guide.pdf> and this topic for additional details.

• U-boot must be rebuilt with USB support enabled.
• The 2GB USB pendrive must be connected to USB0 only and contain two partitions:
  • the first partition must be of type FAT16 or FAT32 and contains the uImage (Linux Kernel) file in the root directory
  • the second partition must be of type ext2 or ext3 and contains the target filesystem (the same contents of /home/<useracct>/workdir/filesys)

Note: The command usb start sometimes hangs on the message scanning bus for storage devices.... If this happens to you, stop the macro from executing, reset the board and reload the script file.

The script below works with a linux kernel in SPI and a MMC/SD card that contains the root filesystem

• The SPI Flash should be pre-loaded with a linux kernel located at address 0x1e0000 (Primus U-boot is not able to initialize and load a kernel from the SD card). The production boards will have the kernel preloaded. For additional details on how to do this, please check this topic and section 5.4.2 of the <LSP_02.20_OMAP-L137_User_Guide.pdf>
• The last parameter of the sf read command must be equal or greater than the size of the linux kernel image.

What is a TeraTerm INI?[edit]

When TeraTerm starts, it runs TERATERM.INI to setup the console. Once you have set your serial terminal to the correct baude rate (via 'Setup->Serial') on COM1 (via 'Setup->General->Default Port'), you can save the setup via 'Setup->Save Setup.' Save this setup in the TeraTerm Installation directory by overwriting TERATERM.INI. Now your TeraTerm will be setup correctly every time you start it.

To run the above scripts, you may need to add a line delay of 100ms (otherwise the lines can become concatenated) by setting the Transmit delay to 100 ms/line (via 'Setup->Serial'). You'll probably want to save this modification in TERATERM.INI to avoid having to modify it every time you start TeraTerm.

Tera Term (alternatively TeraTerm) is an open-source, free, software implemented, terminal emulator (communications) program. It emulates different types of computer terminals, from DEC VT100 to DEC VT382. It supports telnet, SSH 1 & 2 and serial port connections. It also has a built-in macroscripting language (supporting Onigurumaregular expressions) and a few other useful plugins.

History[edit]

The first versions of Tera Term were created by T. Teranishi from Japan. At the time, it was the only freely available terminal emulator to effectively support the Japanese language. Original development of Tera Term stopped in the late 1990s at version 2.3, but other organizations have created variations.

In October 2002, Ayera Technologies released TeraTerm Pro 3.1.3 supporting SSH2 and added multiple other features like a built-in web server for API integration with external systems, recurring 'keep-alive' commands, and ODBC database support via the TT Macro Scripting Language. Ayera Technologies did not make their source open, but does provide limited technical support.

In 2004, Yutaka Hirata, a software designer from Japan, restarted development of the open source version of Tera Term. He added his own implementation of SSH2 and many new features on top of what was part of version 2.3.^[1]

To avoid confusion with version numbers and to indicate that Tera Term developed by Yutaka was more recent than version 3.1.3 from Ayera Technologies, it was decided to give this branch of Tera Term Professional version numbers starting 4.xx.

In January 2005, Boris Maisuradze, together with Yutaka Hirata, started the TeraTerm Support forum where they answered questions from Tera Term users. Posting in this forum was the best way to suggest new features for Tera Term or propose new commands for the Tera Term Macro language. For more than 10 years the forum was hosted on LogMeTT.com website maintained by Boris Maisuradze. Boris also developed several freeware tools that became part of TeraTerm package. Later Boris decided to retire from this project. LogMeTT.com website was shut down and support forums moved to TeraTerm Project site.

Since 2007, Tera Term has been maintained by Tera Term Project (Japanese Developer team) as open source software.

Features[edit]

Tera term supports:^{[citation needed]}

• Serial port connections over UART.
• TCP/IP (telnet, SSH1, SSH2) connections.
• Log replaying.
• Named pipe connection.
• IPv6 communication.
• VT100 emulation and selected VT200/VT300 emulation.
• TEK4010 emulation.
• File transfer protocols (Kermit, XMODEM, YMODEM, ZMODEM, B-PLUS and Quick-VAN).
• Scripts using the 'Tera Term Language'.

Common versions[edit]

• 1.4 Last version supporting Win16; source available in Pascal
• 2.3 Last version released by T. Teranishi
• 3.1.3 Last version released by Ayera. Has issues with scroll window boundaries. Title bar identifies it as version 3.1
• 4.xx Latest OSDN release
