is a popular, lightweight serial port debugging tool used by developers to communicate with hardware via RS232, RS485, and TTL interfaces. Version 5.13.1 includes an English interface, making it accessible for global users working on embedded systems, Arduino projects, and industrial automation. Key Features
Click the small Hex checkbox next to the Send window to switch between ASCII and HEX input.
To establish a successful connection with your hardware (such as an Arduino, STM32, or ESP32), you must match the port settings perfectly. 1. Select the COM Port
Testing RS232, RS485, and Modbus protocols in manufacturing environments. Stable Operation Tips Sscom V5.13.1 English Version
Sscom (often stylized as sscom ) is a lightweight, high-performance serial port debugging assistant originally developed by a Chinese engineer known as "Ding." Unlike generic terminals like PuTTY or HTerm, Sscom was built from the ground up for embedded debugging. It excels at:
: Automatically detects available COM ports and supports high baud rates up to 2Mbps or higher depending on your hardware.
Unlike bloated modern IDEs or basic terminal emulators like PuTTY (which lacks dedicated hardware debugging features), SSCOM is purpose-built for embedded systems development. Key Features of SSCOM V5.13.1 1. Robust Serial Port & Hardware Support is a popular, lightweight serial port debugging tool
Automatically calculates Modbus CRC16, LRC, and basic Sum checksums, saving developers from manual calculations.
For those working with ESP8266, ESP32, 4G LTE, or GPS modules, SSCOM’s multi-string panel is incredibly efficient. You can pre-program commands like AT , AT+CWMODE , and AT+CIFSR in order, executing them step-by-step to test network attachments manually. Modbus RTU Testing
While superficially simple, the English version of V5.13.1 is packed with highly specialized features that cater specifically to the debugging lifecycle: To establish a successful connection with your hardware
Control every aspect of your serial connection. The tool allows you to set custom (from 110 to over 921600 bps, with higher rates requiring hardware support), data bits (5,6,7,8), stop bits (1, 1.5, 2), parity (None, Even, Odd, Mark, Space), and flow control (None, Hardware, XON/XOFF).
If you notice garbled text or "garbage" characters upon booting your hardware, it usually indicates a baud rate mismatch or a clock configuration issue on the microcontroller. Use SSCOM's rapid baud rate switcher to cycle through common frequencies (such as 9600, 57600, and 115200) until the text renders legibly. Why Choose SSCOM V5.13.1 Over Other Serial Tools?
