Version 5.13.1 (released around May 26, 2017) brought several significant improvements:
SSCOM V5.13.1 is a lightweight Windows-based serial port debugging utility commonly used by hardware developers to test communication with microcontrollers like Arduino, STM32, and ESP8266. Changing Language to English
Send and receive fast, connectionless network data packets. 2. Advanced Data Formatting
Always scan the downloaded .exe with Windows Defender or VirusTotal. The legitimate version should not trigger any serious malware alerts (though some antivirus may flag it as "hacktool" due to its low-level serial access – this is often a false positive).
Select your active COM port, set the correct Baud rate, Data bits, Stop bits, and Parity. Sscom V5.13.1 English
Over the years, Sscom has seen versions like 4.2, 5.0, and 5.13. introduced critical improvements:
Use this mode to debug Wi-Fi modules (like ESP8266/ESP32) or Ethernet-to-Serial converters.

| Problem | Likely Cause | Solution | |---------|--------------|----------| | “Cannot open COM port” | Port already in use by Arduino IDE, CuteCom, or another instance of Sscom. | Close other applications. Reboot if necessary. | | Garbled received text | Baud rate mismatch or wrong parity. | Verify device baud rate. Try 9600, 57600, or 115200. | | No data received | TX/RX lines crossed incorrectly. | Ensure device TX → PC RX, device RX → PC TX. | | Sscom crashes on high baud | Driver buffer overflow or USB cable quality. | Reduce baud rate or use a shorter, shielded cable. | | “Access denied” on COM10+ | Windows requires admin rights for high COM ports. | Right-click Sscom.exe → Run as Administrator. |

Extending beyond pure serial communication, Sscom can also act as a . This unified interface is very useful for developers debugging internet-connected devices, allowing them to test both the serial and network layers from a single tool. It can be used to send commands to a network-based MQTT broker or simulate a network server for testing remote devices.
Sscom V5.13.1 is a lightweight yet powerful serial communication debugging tool widely used in embedded systems development, industrial control, and hardware communication testing. Developed by "Daxia Dingding" (丁丁), this software has become an essential companion for electronic engineers, embedded developers, and hardware enthusiasts worldwide. The version 5.13.1 release represents a mature, stable iteration that addresses many previous stability concerns.
Let’s walk through connecting Sscom to a typical USB-to-UART adapter (e.g., CP2102 connected to an Arduino or ESP32).
