Question
Answer and Explanation
Sending a file using Tera Term while waiting between commands typically involves using a scripting language like Tera Term Macro Language (TTL). Here's how you can achieve this:
1. Create a Tera Term Macro (TTL) Script:
- Open a text editor and create a new file with a `.ttl` extension (e.g., `send_file_with_delay.ttl`).
2. Write the Script:
- The script will include commands to connect to the target device, send the file, and introduce delays between commands. Here's an example:
; Connect to the target device (replace with your settings)
connect '192.168.1.100:23' ; Replace with your IP address and port
; Wait for a specific prompt (optional)
;wait 'prompt>'
; Send the command to initiate file transfer (replace with your command)
sendln 'start_transfer'
; Wait for a short delay (in milliseconds)
pause 1000
; Send the file using the B-Plus protocol (replace with your file path)
bplusend 'C:\path\to\your\file.txt'
; Wait for another delay
pause 2000
; Send a command after the file transfer (optional)
sendln 'end_transfer'
; Close the connection
disconnect
; Exit Tera Term
exit
3. Explanation of the Script:
- `connect '192.168.1.100:23'`: Connects to the specified IP address and port. Replace with your target device's connection details.
- `wait 'prompt>'`: (Optional) Waits for a specific prompt before proceeding. Useful if the target device requires a login or specific state.
- `sendln 'start_transfer'`: Sends a command to the target device to initiate the file transfer. Replace with the appropriate command for your device.
- `pause 1000`: Pauses the script execution for 1000 milliseconds (1 second). Adjust the delay as needed.
- `bplusend 'C:\path\to\your\file.txt'`: Sends the specified file using the B-Plus protocol. Replace with the actual path to your file.
- `sendln 'end_transfer'`: (Optional) Sends a command after the file transfer is complete.
- `disconnect`: Closes the connection to the target device.
- `exit`: Closes Tera Term.
4. Run the Script in Tera Term:
- Open Tera Term.
- Go to `Control` -> `Macro`.
- Select the `.ttl` file you created.
- The script will execute, connecting to the device, sending the file, and waiting between commands as specified.
5. Important Considerations:
- File Transfer Protocol: The example uses the B-Plus protocol (`bplusend`). You might need to use a different protocol (e.g., XMODEM, YMODEM, ZMODEM) depending on your target device. Use the corresponding command in the script (e.g., `xmodemsend`, `ymodemsend`, `zmodemsend`).
- Command Syntax: The commands to initiate and end the file transfer (`start_transfer`, `end_transfer`) are specific to your target device. Replace them with the correct commands.
- Delays: Adjust the `pause` values to match the time required by your target device to process commands and transfer data.
- Error Handling: For more robust scripts, you can add error handling using `if` statements and error codes.
By using a Tera Term Macro script, you can automate the process of sending files with delays between commands, making it easier to manage complex interactions with serial devices or network equipment.
