Double-clicking a port opens a built-in serial terminal for it.\n\nUseful during embedded development when you want to watch ports enumerate and talk to them without keeping Device Manager and a separate terminal program open.\n\n![The COM port list widget](PortList.png)\n\n## Features\n\n- **Live port list** — port name, VID:PID, age, a colour status dot (green = free, red = open by another process, yellow = just appeared), open/free status, serial number / hub location, and the Windows description.\n- **Flash on connect** — a newly appeared port flashes amber and fades back over the highlight duration; ports present at startup don't flash.\n- **Removed ports linger** — unplugged ports stay listed in red and fade out for a configurable time so you can see what just disappeared.\n- **Custom names** — give any device a memorable label, keyed by VID:PID:serial so it sticks across re-plugs.\n- **Stays out of the way** — always-on-top (optionally dropped after idle), optional move-to-back on idle, and an opacity fade when you're not interacting with it. Transparency is adjustable.\n- **Per-device memory** — names, serial settings, and terminal window size/position are saved per device in `settings.json`.\n\n### Using it\n\n- **Open a terminal** — click a row's **Status** cell. If the port is busy or the device is unplugged, the row shows *waiting* and the terminal opens automatically as soon as the port is free again.\n- **Edit a custom name** — double-click the **Serial / Loc** cell, type a name, and press **Enter** (**Esc** cancels). Clear the text to remove the name.\n- **Edit settings** — click the **⚙** button in the title bar. The dialog covers highlight duration, how long removed ports stay, always-on-top and its idle drop, move-to-back on idle, the fade-after-idle delay (0 = fade immediately on leaving), and live-preview sliders for window and terminal transparency.\n\n## Terminal\n\nA serial terminal opens in its own borderless window per device. Each remembers its own size and position.\n\n![The serial terminal window](Terminal.png)\n\n- **Send / receive** — RX and TX are colour-coded in the output pane; type in the input line and press **Enter** to send, with a configurable line ending.\n- **Smart auto-scroll** — follows new data only when you're already at the bottom, so scrolling up to read holds your position.\n- **Connect / Disconnect** — toggle the connection from the title bar; the row's status reflects the live connection state.\n- **Reconnect on unplug** — optionally keeps the terminal open when the device is removed and reconnects automatically when it returns.\n- **Modem lines** — optional title-bar **RTS** / **DTR** buttons to drive those outputs (green = asserted), plus live **CTS** / **DSR** / **DCD** indicators. Choose *None*, *RTS/DTR* (controls only), or *Full* (controls + indicators) per device.\n- **Pin (📌)** — toggle the terminal's always-on-top independently of the main window.\n- **Clear** the output, or open the **⚙** port settings.\n- **Resizable** from any edge or corner; drag the title bar to move.\n\n### Port settings\n\nOpen the terminal's **⚙** to set **baud, data bits, parity, stop bits, line ending, signals** (None / RTS/DTR / Full), and **reconnect-on-unplug**. Settings are saved per device (VID:PID:serial) and applied immediately on save.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fknifter%2Fcom_monitor","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fknifter%2Fcom_monitor","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fknifter%2Fcom_monitor/lists"}
