TeraTerm Project. TeraTerm Project would have been developed terminal emulator 'Tera Term' and SSH module 'TTSSH'. This software is open source software under BSD License.This is Tera Term Pro 2.3 succession version and is being officially recognized by the original author. Tera Term is a free software. Telnet connection, serial port connection, TCP/IP. How to use Tera Term for the Serial. Good source of inspiration for creating more complex Teraterm macros. For example:; sample macro of Tera Term. Tera Term has an entire scripting language called Tera Term Language (TTL). You can find all the commands on their website. Install Teraterm 4.60.zip (Save file to desktop and install) Start Tera Term program and select the radio button labeled 'Serial'. Select the COM port from the drop down menu for the device you are going to connect to, then click 'OK'. Click on 'Setup' from the menu bar and select 'Serial Port' from the drop down window.

Miniterm¶

Miniterm is now available as module instead of example.see serial.tools.miniterm for details.

I am using a Tera Term over a serial port to do some testing on a board. Recently I found out I can do some scripting in Tera Term so I have been doing research to help automate and make testing a little easier. Hello, I would like to control a device connected to my PC over a serial cable. Im really a newbies in Auto-It and I managed to get a hyperterminal-like program (in this case Tera Term) launched, the serial port configured and opened. I see the character strings coming out of the serial port, but.

miniterm.py

The miniterm program.

setup-miniterm-py2exe.py

This is a py2exe setup script for Windows. It can be used to create astandalone miniterm.exe.

TCP/IP - serial bridge¶

This program opens a TCP/IP port. When a connection is made to that port (e.g.with telnet) it forwards all data to the serial port and vice versa.

This example only exports a raw socket connection. The next examplebelow gives the client much more control over the remote serial port.

• The serial port settings are set on the command line when starting theprogram.
• There is no possibility to change settings from remote.
• All data is passed through as-is.

tcp_serial_redirect.py

Main program.

Single-port TCP/IP - serial bridge (RFC 2217)¶

Simple cross platform RFC 2217 serial port server. It uses threads and isportable (runs on POSIX, Windows, etc).

• The port settings and control lines (RTS/DTR) can be changed at any timeusing RFC 2217 requests. The status lines (DSR/CTS/RI/CD) are polled everysecond and notifications are sent to the client.
• Telnet character IAC (0xff) needs to be doubled in data stream. IAC followedby another value is interpreted as Telnet command sequence.
• Telnet negotiation commands are sent when connecting to the server.
• RTS/DTR are activated on client connect and deactivated on disconnect.
• Default port settings are set again when client disconnects.

New in version 2.5.

rfc2217_server.py

Main program.

setup-rfc2217_server-py2exe.py

This is a py2exe setup script for Windows. It can be used to create astandalone rfc2217_server.exe.

Multi-port TCP/IP - serial bridge (RFC 2217)¶

This example implements a TCP/IP to serial port service that works withmultiple ports at once. It uses select, no threads, for the serial ports andthe network sockets and therefore runs on POSIX systems only.

• Full control over the serial port with RFC 2217.
• Check existence of /tty/USB0...8. This is done every 5 seconds usingos.path.exists.
• Send zeroconf announcements when port appears or disappears (usespython-avahi and dbus). Service name: _serial_port._tcp.
• Each serial port becomes available as one TCP/IP server. e.g./dev/ttyUSB0 is reachable at <host>:7000.
• Single process for all ports and sockets (not per port).
• The script can be started as daemon.
• Logging to stdout or when run as daemon to syslog.
• Default port settings are set again when client disconnects.
• modem status lines (CTS/DSR/RI/CD) are not polled periodically and the servertherefore does not send NOTIFY_MODEMSTATE on its own. However it responds torequest from the client (i.e. use the poll_modem option in the URL whenusing a pySerial client.)

Requirements:

• Python (>= 2.4)
• python-avahi
• python-dbus
• python-serial (>= 2.5)

Installation as daemon:

• Copy the script port_publisher.py to /usr/local/bin.
• Copy the script port_publisher.sh to /etc/init.d.
• Add links to the runlevels using update-rc.dport_publisher.shdefaults99
• That’s it :-) the service will be started on next reboot. Alternatively runinvoke-rc.dport_publisher.shstart as root.

New in version 2.5: new example

port_publisher.py

Multi-port TCP/IP-serial converter (RFC 2217) for POSIX environments.

port_publisher.sh

Example init.d script.

wxPython examples¶

A simple terminal application for wxPython and a flexible serial portconfiguration dialog are shown here.

wxTerminal.py

A simple terminal application. Note that the length of the buffer islimited by wx and it may suddenly stop displaying new input.

wxTerminal.wxg

A wxGlade design file for the terminal application.

wxSerialConfigDialog.py

A flexible serial port configuration dialog.

wxSerialConfigDialog.wxg

The wxGlade design file for the configuration dialog.

setup-wxTerminal-py2exe.py

A py2exe setup script to package the terminal application.

Unit tests¶

The project uses a number of unit test to verify the functionality. They allneed a loop back connector. The scripts itself contain more information. Alltest scripts are contained in the directory test.

The unit tests are performed on port loop:// unless a different devicename or URL is given on the command line (sys.argv[1]). e.g. to run thetest on an attached USB-serial converter hwgrep://USB could be used orthe actual name such as /dev/ttyUSB0 or COM1 (depending on platform).

run_all_tests.py

Collect all tests from all test* files and run them. By default, theloop:// device is used.

test.py

Basic tests (binary capabilities, timeout, control lines).

test_advanced.py

Test more advanced features (properties).

test_high_load.py

Tests involving sending a lot of data.

test_readline.py

Tests involving readline.

test_iolib.py

Tests involving the io library. Only available for Python 2.6 andnewer.

test_url.py

Tests involving the URL feature.

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.
