SSCOM is one of the most popular serial port debugging tools used by embedded systems engineers, hardware developers, and IoT programmers. Originally developed in Chinese, the allows global developers to access its powerful features without a language barrier.

Engineers debugging STM32, ESP32, Arduino, or Raspberry Pi Pico projects use SSCOM to monitor debug output, send test commands, and validate communication protocols.

QA engineers use SSCOM’s auto-send and logging features to stress-test serial interfaces, verify data integrity, and document performance metrics.

This feature transforms SSCOM from a simple text terminal into an intelligent diagnostic hub.

In the lower text area (the send box), type a simple AT command (e.g., AT for a modem or GSM module). Tick the checkbox, as many devices require a carriage return at the command's end. Click "Send" . You should see an OK or other response in the upper receive window.

To get started, download the latest SSCOM V5.13.1 English version from a trusted source, connect your device, configure your parameters, and begin exploring the world of serial communication with one of the most trusted tools in the industry.

: Supports RS232, RS485, and USB-to-serial adapters.
