Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

FSterm v1.2.4

👉 A lightweight ANSI terminal emulator with serial, TCP, and UDP connectivity.

FSterm is a lightweight, high-performance ANSI terminal designed for communicating with serial and network-connected devices without unnecessary complexity. Despite its compact portable size, it delivers an impressive feature set for developers, technicians, and hardware enthusiasts. Connect through serial ports or over TCP and UDP, enjoy comprehensive ANSI terminal emulation with truecolor support, multiple terminal sizes, mouse selection, and flicker-free rendering, then take advantage of the powerful GrafANSI© extension to display images, diagrams, shapes, pointers, layered graphics, and device-triggered audio across the same connection. Version 1.2.4 further improves performance with significantly faster rendering, smoother scrolling, expanded screenshot capabilities, command-line automation, customizable cursor styles, a wider baud rate range up to 921600, Slim-GUI mode, and permanent background image support, making FSterm a fast, flexible, and capable terminal for everything from embedded development to industrial equipment and diagnostics.
