Understanding the Line-Ending Problem
When connecting to remote servers or using specific terminal emulators, the way new lines are interpreted can cause significant visual clutter. On Unix-like systems, a line break is typically represented by a single Line Feed (LF) character. However, older Windows applications and some legacy protocols expect a Carriage Return followed by a Line Feed (CRLF). When MobaXterm sends an LF without the preceding CR, the cursor may not move to the beginning of the next line correctly, resulting in text overlapping or misalignment.
This issue is particularly noticeable when running interactive programs, scrolling through logs, or using tools that do not explicitly handle line endings. By enabling implicit CR, you instruct MobaXterm to inject the necessary carriage return before every line feed it transmits to the remote host. This mimics the behavior expected by many Windows-centric interfaces and ensures consistent output formatting across different environments.
Navigating Global Settings
To apply this change globally, you must access the main configuration interface of MobaXterm. Start by launching the application on your Windows 11 machine. Once the main window appears, locate the toolbar at the top of the interface. Click on the Settings button, which is often represented by a gear icon or labeled clearly in the menu bar. This action opens the comprehensive settings dialog where you can adjust both user-specific and system-wide preferences.
If you cannot find the button immediately, look for the Configuration menu item in the top-left corner. Selecting this will also open the same settings panel. It is important to make changes in the global settings if you want this behavior to apply to all your current and future sessions, rather than just one specific connection profile. For users who manage multiple types of connections, understanding the hierarchy between global defaults and individual profile overrides is crucial.
Differentiating Global vs. Profile Settings
MobaXterm allows granular control over terminal behavior. While global settings affect the entire application, individual session profiles can override these defaults. If you have previously customized a specific server connection, its profile might have explicit line-ending settings that conflict with the global configuration. Therefore, after adjusting the global setting, you should verify that your active sessions are not manually overriding this preference. This ensures that the fix applies consistently across all your workflows.
Enabling Implicit CR Every LF
Once inside the Settings window, navigate to the Terminal tab. This section contains various options related to how the terminal emulator renders text and handles input. Scroll down until you locate the checkbox labeled Implicit CR every LF. Check this box to enable the feature. The interface may require you to confirm the change or simply apply it immediately depending on your version of MobaXterm.
After checking the box, click the OK or Apply button at the bottom of the dialog to save your changes. You do not need to restart MobaXterm for this setting to take effect in new sessions. However, if you have existing open terminals, you may notice immediate improvements in text alignment as they process the next batch of output. If the issue persists, consider restarting the terminal session to ensure the new parameters are loaded into the current process.
Verifying the Fix
To confirm that the setting is working correctly, perform a simple test. Open a terminal session connected to a remote Linux server. Run a command that produces multiple lines of output, such as ls -l / or a loop script. Observe the output carefully. If the text aligns properly on the left side of the screen and does not overlap with previous lines, the implicit CR feature is functioning as intended. You can also try pressing Enter repeatedly to see if each new prompt starts on a fresh line without residual characters from the previous line.
If you encounter any remaining display issues, check if the remote shell is sending special escape sequences that might interfere with the cursor position. In rare cases, terminal emulation modes (such as VT100 vs. ANSI) can interact differently with line-ending conversions. Ensuring that your terminal type is set to xterm or linux in the session configuration can help maintain consistency.

Refer to our guide on Profile Termination Behavior Configuration in Advanced Profile Settings to learn how to manage session exits safely. Additionally, if you are tunneling SSH connections, proper configuration of those tunnels is essential for secure communication.

Frequently Asked Questions
Does this setting affect local Windows terminals?
Yes, enabling implicit CR affects all terminal windows within MobaXterm, including local bash or PowerShell instances. This might cause slight formatting differences in native Windows outputs but generally improves compatibility with cross-platform scripts.
Why do I still see overlapping text after enabling this?
Overlapping text may persist if the remote server is sending back incorrect cursor positioning codes or if your terminal emulation mode is mismatched. Try switching the terminal type in your session settings to xterm to resolve encoding conflicts.
Can I enable this for only one specific server?
No, the "Implicit CR every LF" option is located in the global Terminal settings. To apply it selectively, you would need to disable the global setting and instead use custom environment variables or aliases in the remote shell to handle line endings manually.
Is this setting compatible with PuTTY?
MobaXterm has its own internal terminal emulator based on similar principles to PuTTY. While the concept is similar, the specific checkbox name and location differ. MobaXterm handles this natively in its global config, whereas PuTTY requires configuring the "Line-discipline" options per session.
Will this increase bandwidth usage?
The impact on bandwidth is negligible. Adding a single carriage return character (one byte) for every line feed adds minimal overhead, even in high-volume log streaming scenarios. The benefit of readable output far outweighs the tiny increase in data transmission.
