The software automatically detects available COM ports upon startup or hardware insertion.

Launch the executable file. Click the "Port" dropdown menu and select your device. Set the baud rate to match your microcontroller firmware (default is often 115200). Step 3: Open the Connection

Sscom V5.13.1 English Version is a popular, lightweight serial port debugging utility used widely by embedded engineers, hardware developers, and IoT programmers. It allows seamless communication between a computer and external hardware devices via serial interfaces. Sscom V5

While the software offers standard presets (9600, 115200, etc.), it also allows users to input non-standard, custom baud rates manually to match specialized hardware clocks. 5. Built-in Data Tools

Includes an "Auto-Send" mode for repetitive data transmission and the ability to save predefined command scripts for rapid testing.

If the app fails to detect your USB-to-TTL drivers, right-click the executable and select Run as Administrator . Configuring the Serial Connection

You can pre-define a list of commands and send them sequentially or on-demand. This is invaluable for testing AT commands on modems or initializing GPS modules.
