Sscom V5.13.1 English

By logging exact HEX data, developers can reverse-engineer communication between a PC and a proprietary device.

One of the standout features is the "Auto Reply" function. You can define a library of strings or HEX patterns and set responses. For example, if the device sends "AT", Sscom can automatically reply with "OK". This is invaluable for testing sensors or simulating a server.

In the HEX send panel, you can automatically append checksums (XOR, SUM, CRC16) to your data frames. No more manual calculation.

SSCom V5.13.1 (English Version): The Unofficial User Guide

SSCom (often referred to as SSCOM) is a popular, lightweight, and robust serial port debugging tool widely used in embedded systems development, IoT debugging, and electronics hobbyism. It is favored over alternatives like Putty or TeraTerm because of its rich feature set (like HEX display, timestamping, and automated protocols) packed into a single, small executable.

Note: This software is developed by a Chinese developer. While V5.13.1 may have partial English or require translation, this guide covers the standard functionality based on the universally recognized interface. One of the standout features is the "Auto Reply" function
