While newer versions like SSCOM v5.x have updated the interface and added features like multi-port monitoring, the "32" in the original name often refers to its roots in the 32-bit Windows era—a time when serial communication (RS232/RS485) was the undisputed king of industrial connectivity. Despite the rise of USB and wireless protocols, the underlying UART (Universal Asynchronous Receiver-Transmitter) logic remains the primary way low-level hardware communicates.
It is ugly, it is old, and it works flawlessly. Keep it on a USB stick. You never know when you'll need to send a raw 0x0D instead of \r\n . sscom 32
(often just called SSCOM ) is a very popular, lightweight, and robust serial port debugging tool for Windows. It is widely used by embedded systems engineers, IoT developers, and hobbyists to communicate with hardware devices like Arduino, ESP8266, ESP32, STM32, and RS232/RS485 modules. While newer versions like SSCOM v5
: A built-in timer allows you to send data packets at regular intervals, which is useful for testing device responsiveness over time. File Transfer Capability Keep it on a USB stick
: Set the communication speed. Common defaults are 9600 or 115200 , but it can go up to 2,000,000 for high-speed modules.
: Ensure Data Bits , Stop Bits , and Parity are configured according to your device's manual.
