Plug in your USB-to-UART adapter (CP2102, CH340, FTDI). Open → Ports (COM & LPT) to identify the COM port number.
Automatically calculates and appends Modbus RTU CRC16, Checksum8, or Checksum16 to your outgoing strings.
Supports a wide range of baud rates, from standard 300bps up to high-speed 921600bps .
One of the most appealing aspects of Sscom V5.13.1 is its incredibly low system resource usage. It is compatible with a vast range of Windows operating systems, from Windows XP to Windows 11, on both 32-bit and 64-bit architectures. It requires only a minimal amount of RAM and less than 1MB of disk space. The application does not rely on external runtimes like .NET Framework, making it functional on even the most stripped-down or legacy systems. Sscom V5.13.1 English Version
Many microcontrollers and modems require a line ending to process a command. Ensure the SendNewLN (Send New Line) box is checked. Conclusion
Engineers, developers, and makers frequently need to communicate with hardware modules via serial interfaces. Whether configuring an AT-command-based GSM module, debugging an Arduino project, or analyzing Modbus traffic over RS485, a reliable serial terminal is indispensable.
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 Plug in your USB-to-UART adapter (CP2102, CH340, FTDI)
Switch seamlessly between ASCII string view and Hexadecimal (HEX) view for raw byte analysis.
Check the HEX Send box if you are typing raw hex pairs (e.g., 41 42 43 ). Keep it unchecked for plain text.
Properly setting up the communication parameters is critical to avoiding frame errors and data corruption. Supports a wide range of baud rates, from
Click the red question mark symbol () to define data rules.
At its fundamental level, SSCOM is a serial terminal emulator. It facilitates communication between a host PC and a target microcontroller (MCU), module, or peripheral via serial communication protocols—most commonly UART (Universal Asynchronous Receiver-Transmitter), but also supporting SPI and I2C with appropriate hardware bridges.
Getting started is incredibly simple, thanks to the tool's "green" or portable design.
If you encounter issues while using the software, check the following common failure points:
