Versions:
SimpleCom 1.2.7, published by YaSuenag, is a lightweight Windows console application that turns any standard command-line window into a no-frills serial terminal, enabling engineers, embedded developers, and network technicians to exchange ASCII or binary data with routers, switches, IoT boards, GPS receivers, and other RS-232/RS-485/TTL devices without loading a heavy GUI. Because it runs inside the familiar cmd.exe or PowerShell environment, users can combine real-time serial capture with native batch scripts, PowerShell automation, or Unix-style pipelines, making it equally suited for quick ad-hoc checks, long-term logging, manufacturing-line flashing routines, or headless server diagnostics where a minimal footprint and zero installer overhead are valued. The single 32-bit executable works on every Windows version from Windows 7 onward, requires no administrator rights, and stores no registry keys, so it can be carried on a thumb-drive and launched instantly; yet it still honors common baud rates, data bits, parity, stop bits, and flow-control combinations, offers flexible end-of-line translation, and cleanly releases the COM port on exit to avoid the “port in use” conflicts that plague many larger terminal suites. YaSuenag has iterated the program through ten public releases, progressively adding better UTF-8 support, improved error messages, and 64-bit compatibility while keeping the binary under 100 kB. The utility is categorized under System / Serial Communications. SimpleCom is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
