Unlike complex integrated development environments (IDEs) that bundle serial communication as a secondary feature, SSCOM focuses exclusively on providing a straightforward, efficient serial port debugging experience. Its minimalist design philosophy ensures that you can start testing your device within seconds of launching the program.

: Allows opening multiple serial connections at once for comparative testing. Flexible Baud Rates : Supports a wide range from 300 bps up to 921,600 bps. Data Formats

Are you trying to send or configure devices using HEX commands ? Capacitive Soil Moisture with LoRaWAN (English)

: Allows users to input and execute AT commands directly, which is critical for debugging LoRaWAN, GSM, and GPS modules.

Sscom 5.13.1 English serves as a bridge between your computer and external hardware like microcontrollers, sensors, and GPS modules. It supports various communication protocols, including RS232, RS485, and USB-to-TTL. The tool is lightweight, portable, and does not require a complex installation process, making it a favorite for field testing and laboratory environments.

Connect your hardware device (e.g., an Arduino, ESP32, or sensor) to your computer using a standard serial cable or, more commonly, a USB-to-serial adapter (like those using the CH340 or CP2102 chip). Your computer should automatically recognize the device and assign it a COM port number.

The tool supports both ASCII (text) and hexadecimal (HEX) display formats. Users can freely switch between modes to view data in the most appropriate format for their needs. This flexibility is particularly valuable when dealing with binary protocols where HEX representation is essential.

If you see random noise, verify that your baud rate, parity bits, and stop bits match your hardware's specifications.
