Extensive support for custom baud rates and timestamps. Cons: The UI design feels a bit dated (Win7-era aesthetic).

Advanced scripting is limited compared to some paid alternatives.

Problem: "COM port not found" or access denied.

Solution: Close other serial monitors (Arduino IDE, CuteCom). On Windows, check Device Manager → Ports (COM & LPT) for the actual number. Use mode command in cmd to list free ports.

Problem 4: UI Shows Chinese Characters Anyway

• Cause: You have the Chinese executable, not the English version.
• Solution: Re-download the specific "English Version" from a trusted source.

6. Automatic Reply (Echo Emulation)

Configure automatic responses to specific strings. For example, if the device sends "ID?", Sscom can auto-reply with "Sscom-Terminal".

3. The Engineering Workflow: How SSCOM is Actually Used

In practice, SSCOM V5.13.1 is the first tool opened when a new piece of hardware arrives on an engineer's desk. The typical workflow unfolds in distinct phases:

1. The "Sanity Check": Before writing a single line of C/C++ code, an engineer uses SSCOM to verify the hardware. Can the PC see the COM port? Is the baud rate correct? Does the device respond to a basic "AT" command? If SSCOM cannot communicate with the board, no software driver will either.
2. Firmware Bring-up: As the embedded developer writes initialization routines for sensors (like an MPU6050 accelerometer or an ESP8266 Wi-Fi module), they insert printf() statements via the MCU's UART peripheral. SSCOM becomes the "console.log" of the embedded world, printing out register values and state machine transitions.
3. Protocol Reverse Engineering: Often, engineers must interface with cheap, undocumented Chinese hardware modules. By connecting the module's Tx pin to the PC's Rx pin

SSCOM V5.13.1 is a lightweight, portable serial port debugging tool widely used for developing and testing embedded systems. Because it is often distributed in Chinese by default, the first step for many users is enabling the English interface.  1. Initial Setup and Language Configuration 

SSCOM is a portable application and does not require a traditional installation. 

Launch: Extract the ZIP file and run the sscom5.13.1.exe file directly.

Switch to English: If the interface opens in Chinese, look for a checkbox or button labeled "English" or "Change Language" in the main window. Clicking this will immediately translate the menus and buttons.  2. Establishing a Connection 

To communicate with your hardware (e.g., Arduino, ESP32, or industrial sensors), configure the following: 

Select COM Port: Use the "ComNum" dropdown to select the correct port assigned to your USB-to-Serial adapter.

Communication Parameters: Set the Baud Rate, Data Bits, Stop Bits, and Parity to match your device's specifications. Open Port: Click "OpenCom" to start the session.  3. Sending and Receiving Data 

The interface is split into a receive (monitor) window and a send (input) area.  ASCII vs. HEX:

Check "SendHEX" and "HEXShow" if you are working with hexadecimal bytes.

Leave them unchecked for standard text (ASCII) communication. Cause: You have the Chinese executable, not the

Sending Commands: Type your command in the bottom input box and click "Send".

Enter to Send: Enabling the "Enter to send" option allows you to press the Enter key instead of clicking the button.  4. Advanced Debugging Features 

Extended Commands (EXT): Click the "EXT" button to open a side panel where you can save a list of preset commands for quick access.

Automatic Sending: You can set an interval (in milliseconds) and check "AutoSend" to loop a specific command continuously.

Timestamps: Enable timestamps to track exactly when data packets are received, which is useful for analyzing communication latency.

Waveform Display: SSCOM can interpret incoming data and plot it as a real-time waveform, helpful for monitoring sensor values like temperature or voltage.  5. Troubleshooting Tips

Feature Highlight – “Advanced Multi‑Port Monitoring & Real‑Time Data Logging”

Overview
SSCOM v5.13.1 (English version) introduces a robust multi‑port monitoring engine that lets you open, view, and control up to 16 serial (COM) ports simultaneously from a single unified interface. Each port is displayed in its own tab, yet you can also create a “combined view” that merges data streams for side‑by‑side comparison or synchronized analysis.

Key Capabilities

| Capability | What It Does | Practical Benefits | |------------|--------------|--------------------| | Independent Port Configuration | Assign individual settings (baud rate, parity, data bits, stop bits, flow control) for each open COM port. | No need to close one session to re‑configure another—perfect for testing devices with different protocols. | | Live Data Merging Window | Drag‑and‑drop any open port into a “merge window” where incoming bytes from all selected ports are displayed together, each prefixed with a configurable port identifier. | Instantly spot timing relationships, cross‑device communication patterns, or protocol collisions. | | Per‑Port Hex/ASCII Toggle | Switch any port’s view between pure ASCII, pure hexadecimal, or a split hex/ASCII mode. | Quickly decode human‑readable messages while still being able to inspect raw byte values. | | Real‑Time Logging with Timestamp Granularity | Enable logging per port or for the merged view. Each line can include:
• Date + time (down to milliseconds)
• Port ID
• Direction flag (RX/TX)
• Optional custom tag | Generates ready‑to‑import logs for Excel, MATLAB, or custom parsers. Millisecond timestamps are essential for debugging time‑critical embedded protocols. | | Dynamic File Capture & Replay | Capture traffic to a file on‑the‑fly (auto‑rotate when a size limit is reached). Later, load the capture and replay it on any selected port at original timing or at a user‑defined speed factor. | Perfect for regression testing: record a successful session once, then replay it repeatedly to verify firmware changes. | | Conditional Triggers & Auto‑Responses | Define simple trigger rules (e.g., “when the string ‘ERROR’ appears on COM3, send ‘RESET\r\n’ on COM5”). Supports regex patterns and multi‑byte binary sequences. | Automates repetitive diagnostic steps and reduces manual intervention during long‑run tests. | | Port‑Specific Macro Recorder | Record a sequence of keystrokes or command strings for a given port, save it as a macro, and bind it to a toolbar button or hotkey. | One‑click execution of complex command sequences (e.g., bootloader entry, firmware upgrade commands). | | Graphical Signal Analyzer (Optional Plug‑in) | For ports that carry binary waveform data (e.g., UART‑based sensor streams), the built‑in analyzer can plot voltage‑level equivalents, frequency spectra, or custom charts based on user‑defined parsing scripts (Python/JavaScript). | Turns raw serial data into visual insights without needing external oscilloscopes. |

Why This Feature Matters

• Multi‑device debugging: Modern embedded projects often involve several microcontrollers, sensors, and peripherals that talk over separate serial lines. Being able to watch all of them at once cuts down the “switch‑tab” overhead and eliminates missing critical events that happen while you’re focused on another port.
• Accurate timing analysis: Millisecond‑resolution timestamps combined with a merged view give you the same diagnostic power as a hardware logic analyzer but with the convenience of a software tool.
• Automation & repeatability: Triggers, auto‑responses, and macro playback turn a manual, error‑prone process into a deterministic test script, which is essential for CI pipelines or production validation.

Getting Started

1. Open Ports – Click File → Open Port, select the COM number, and set the communication parameters. Repeat for each device.
2. Create a Merge Window – Drag the tab of any open port into the “Merge View” area at the bottom of the main window.
3. Enable Logging – Right‑click the merge window → Start Logging, choose a folder, and set the timestamp format.
4. Set a Trigger – Tools → Triggers, add a new rule, specify the source port, pattern (plain text or regex), and the action (send command, start recording, etc.).
5. Save & Reuse – All port configurations, merge layouts, and trigger definitions can be saved as a .sscproj project file for quick re‑loading later.

Bottom Line
The Advanced Multi‑Port Monitoring & Real‑Time Data Logging feature in SSCom v5.13.1 transforms a simple serial terminal into a full‑scale, multi‑device debugging workstation—giving engineers the visibility, precision, and automation they need to troubleshoot complex embedded systems efficiently.
