HTerm 0.8.9, published by Tobias Hammer, is a lightweight, cross-platform terminal utility engineered specifically for serial-port communication, positioning itself in the Developer Tools / Serial Terminal category. Built to run natively on both Windows and Linux, the program opens an immediate, text-based conduit to embedded systems, network appliances, microcontroller boards, GPS receivers, industrial PLCs, and any other device that exposes an RS-232, RS-485, or TTL-level UART interface. Users launch HTerm, choose the matching COM or tty port, set baud rate, data bits, parity, stop bits and handshaking, and instantly begin duplex data exchange; a color-coded display shows transmitted and received bytes in either ASCII or hexadecimal format, while an integrated keyboard-emulation pane lets operators inject predefined command strings, repetitive test sequences, or single-byte control codes without manually retyping. Logging capabilities capture entire sessions to plain-text or binary files for later auditing, scripting, or debugging, and a scroll-back buffer permits inspection of traffic that has already left the visible window. Because the application ships as a single executable with no installation routine, it fits conveniently on a USB stick for field technicians, OEM support staff, hardware hackers, and firmware developers who need a dependable, zero-footprint serial monitor on lab benches, production floors, or customer sites. HTerm 0.8.9 is the first and therefore current version offered by the author. The software 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.
