Teraterm Command Line Serial

You will be prompted to select your input source. Select the 'Serial'-bullet and select the respective port from the dropdown menu, then click 'OK' Then press any button (most likely 'Enter'-button) to trigger the program to connect and display the console login menu. 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?

You should initially be presented with a 'TeraTerm: New connection' pop-up within the program. Here, you can select which serial port you'd like to open up. Select the 'Serial' radio button. Then select your port from the drop-down menu.

Connects.

Remarks

If MACRO is not linked to Tera Term, this command runs Tera Term with , and links it to MACRO. For example:

If MACRO has already been linked to Tera Term and Tera Term is not connected to the host, this command causes Tera Term to connect to the host specified by .

Free floorplan 3d design suite 10. If MACRO has already been linked to Tera Term and Tera Term has already been connected to the host, this command is ignored.

As a result of this command, the system variable 'result' is set to one of the following values depending on the link and connection status:

To test the current link and connect status before executing the 'connect' command, use the 'testlink' command.

Communication commands except 'connect', 'cygconnect' and 'testlink' can not be executed before the link is established.

Connection method

There are 3 types of connection you can establish from Tera Term macro:

• Telnet connection (port 23)
• SSH1 or SSH2 connection (port 22)
• General connection
• Connection via COM port

Telnet connections

Using /nossh is strongly recommended. Without this parameter Tera Term will start connecting with the same method (telnet or SSH) that was used during last time when teraterm.ini file was saved. In case it was SSH than your macro will try to connect via SSH and will eventually fail.

SSH connections

This way will start SSH connection without defining whether SSH1 or SSH2 has to be used.

Parameters /1 and /2 force to use SSH1 or SSH2 method.

Note: path to /keyfile should be relative to Teraterm directory. Absiolute path does not work.

Above 9 ways allow to skip popup dialog and pass username and password directly from macro. Please note that /auth=password or /auth=publickey or /auth=challenge is the parameter saying that authentication will be done by entering password or private-key-file thus you should not replace the word 'password' or the word 'publickey' in it with actual password.

Above 3 ways allow to skip popup dialog and pass username directly from macro.

Above 9 ways pass username and authentication method directly from macro, and the popup asks for password.

General connection

Note: This option value is connecting timeout value(per seconds). Connecting to myserver could be canceled after timeout has occurred with the specified value. Conversely, no action if the value is zero. The default value is zero. Also this value would be saved as `ConnectingTimeout' entry in teraterm.ini file.

Connections via COM port

Here x represents COM port number. For example to connect via COM port 1 the command will look like: connect '/C=1'

Examples

Note

1. In these examples parameters shown with Italic font have to be replaced with their actual values.
2. The password can contain space character. To represent space inside the password replace it with '@' character. If '@' character itself is part of the password than it has to be replaced with 2 consecutive '@' characters '@@'.
3. Please remember that entering actual username and password in Tera Term macro will cause them to be stored as an open text and it is your responsibility to keep such macro is secure location.
4. When a user re-connect the remote host soon after disconnecting the server, a user could not connect the server. For more detail, refer to 'here'.

Please remember that entering actual username and password in TeraTerm macro will cause them to be stored as an open text and it is your responsibility to keep such macros in secure place.

A little bit better practice is to use getpassword and passwordbox commands that store encrypted passwords in the file.

About setsync
It is highly recommended to use the macro command

Quote:

right after the command connect. This command switches TeraTerm into synchronous communication mode in which the buffer never overflows. See TeraTerm Macro help for more details.

The serial supports serial communication between the BBC micro:bit and another computer. Basically, this allows you to send data from the micro:bit to your own computer. This is very useful for debugging purposes: you can add write line statements in your code and see them display on your computer as the program executes.

The code below shows a simple script that sends a line when the BBC micro:bit starts and another line each time the button A is pressed.

Data is also automatically streamed to serial by the bar graph blockand picked up by the editor. This data can be streamed to the cloud as well.

How to read the micro:bit's serial output from your computer

Unfortunately, using the serial library requires quite a bit of a setup.

Windows earlier than 10

If you are running a Windows version earlier than 10, you must install a device driver (for the computer to recognize the serial interface of the micro:bit).

Also, if you don't see the serial port as one of your computer's devices, you might need to update the firmware on the micro:bit. Find the device name for the attached serial port in the following instructions for your operating system.

Windows > Tera Term

• Install the terminal emulator Tera Term. At the time of this writing, the latest version is 4.88 and can be downloaded from here. Follow the instructions from the installer.

Once both the driver and the terminal emulator are installed, plug in the micro:bit and wait until the device is fully setup. Then, open TeraTerm.

• Hit File > New Connection
• Check 'Serial'; in the dropdown menu, pick the COM port that says 'mbed Serial Port'. Hit Ok.
• In the menus, hit Setup > Serial Port and set the baud rate to 115200.

Teraterm Macro Command

You should be good. Feel free to hit Setup > Save Setup in the menus to erase the default configuration file with a new one so that you don't have to type in the settings again.

Please note that Windows will assign you a different COM port if you plug in another micro:bit. If you're juggling between micro:bits, you'll have to change the COM port every time.

Windows > Putty

If you prefer another terminal emulator (such as PuTTY), here are some instructions.

• Open Windows's Device Manager; expand the section called 'Ports (COM & LPT)'; write down the com number for 'mbed Serial Port' (e.g. COM14)
• Open PuTTY; on the main screen, use the following settings: Serial / COM14 / 115200. Replace COM14 with the COM port number you wrote down previously. Feel free to type in a name and hit 'Save' to remember this configuration.

• (optional): in the 'Terminal' section, check 'implicit cr in every lf'

Linux

• Install the program screen if it is not already installed.
• Plug in the micro:bit.
• Open a terminal.
• Find which device node the micro:bit was assigned to with the command ls /dev/ttyACM*.
• If it was /dev/ttyACM0, type the command screen /dev/ttyACM0 115200. If it was some other device node,use that one in the command instead. Note: You may need root access to run screensuccessfully. You can probably use the command sudo like this: sudo screen /dev/ttyACM0 115200.
• To exit screen, type Ctrl-ACtrl-D.

Alternative programs include minicom and so on.

Teraterm Script Commands

Mac OS

• Plug in the micro:bit
• Open a terminal
• ls /dev/cu.* will return to you a list of serial devices; one of them will look like /dev/cu.usbmodem1422 (the exact number depends on your computer)
• screen /dev/cu.usbmodem1422 115200 will open up the micro:bit's serial output. To exit, hit Ctrl-ACtrl-D.
