English Version - Sscom V5.13.1

Type AT (for modem) or Hello in the send box. Click Send (or F5). You should see a reply in the receive window.

Solution: Mismatched baud rate or parity. Start with 9600,8,N,1. If hex data looks sane (e.g., 0D 0A every line), it’s likely a baud mismatch. Try standard rates: 4800, 9600, 19200, 115200.

Sscom is a single .exe file. No registry edits, no DLLs, no dependencies. Place it in a folder like C:\Tools\Sscom\.

Yes, for three reasons:

That said, Sscom lacks modern features like:

If you need those, consider alternatives like Serial Studio or IO Ninja. But for raw, fast, reliable serial debugging—Sscom V5.13.1 remains unmatched.

Check RS485 mode (if available) or manually control the RTS pin for direction switching. Sscom’s low latency makes it feasible for Modbus RTU testing.

Many bootloaders (e.g., ESP8266, STM32) require a binary file transfer. Use Sscom’s Send File function with HEX mode enabled. Set DTR/RTS to manually reset the chip before transmission. Sscom V5.13.1 English Version

SSCOM V5.13.1 is a lightweight, portable Windows utility for serial port communication, offering features like multi-port monitoring, HEX/ASCII data transmission, and a wide baud rate range. The tool supports debugging microcontrollers and LoRaWAN/GSM modules, with an English interface toggle allowing for easy setup. Detailed installation and setup instructions are available at drivethelife.com

SSCOM V5.13.1 is a lightweight, portable serial port debugging tool widely used for developing and testing embedded systems. Because it is often distributed in Chinese by default, the first step for many users is enabling the English interface.  1. Initial Setup and Language Configuration 

SSCOM is a portable application and does not require a traditional installation. 

Launch: Extract the ZIP file and run the sscom5.13.1.exe file directly.

Switch to English: If the interface opens in Chinese, look for a checkbox or button labeled "English" or "Change Language" in the main window. Clicking this will immediately translate the menus and buttons.  2. Establishing a Connection 

To communicate with your hardware (e.g., Arduino, ESP32, or industrial sensors), configure the following:  Type AT (for modem) or Hello in the send box

Select COM Port: Use the "ComNum" dropdown to select the correct port assigned to your USB-to-Serial adapter.

Communication Parameters: Set the Baud Rate, Data Bits, Stop Bits, and Parity to match your device's specifications. Open Port: Click "OpenCom" to start the session.  3. Sending and Receiving Data 

The interface is split into a receive (monitor) window and a send (input) area.  ASCII vs. HEX:

Check "SendHEX" and "HEXShow" if you are working with hexadecimal bytes.

Leave them unchecked for standard text (ASCII) communication.

Sending Commands: Type your command in the bottom input box and click "Send".

Enter to Send: Enabling the "Enter to send" option allows you to press the Enter key instead of clicking the button.  4. Advanced Debugging Features  Solution: Mismatched baud rate or parity

Extended Commands (EXT): Click the "EXT" button to open a side panel where you can save a list of preset commands for quick access.

Automatic Sending: You can set an interval (in milliseconds) and check "AutoSend" to loop a specific command continuously.

Timestamps: Enable timestamps to track exactly when data packets are received, which is useful for analyzing communication latency.

Waveform Display: SSCOM can interpret incoming data and plot it as a real-time waveform, helpful for monitoring sensor values like temperature or voltage.  5. Troubleshooting Tips
