Open source · Serial
A serial port on the network, and the console built for it.
Clip BaudHound onto a device's TTL serial header and its console is on WiFi, with the baud rate found for you. BaudHoundTerm, a Windows terminal, finds it on the network, opens it over TLS, and keeps the session, the log and the reconnect. Both are free and open source: the firmware under MIT, the terminal under Apache-2.0.
The problem it solves
The console you need is behind a panel, up a pole, or across the rack.
Switches in a closet, a sensor node on a pole, a board wedged behind a panel: the serial header is where the truth is, and it is never where your laptop is. BaudHound clips on and puts that console on the phone or PC you already have, without a cable across the room and without knowing the port speed first.
What you get
A pocket ESP32-S3 tap reachable from a web page, telnet, TLS or USB.
Automatic baud detection from 9600 to 921600, with RX and TX swapped back if the wires are crossed.
A Windows terminal that finds the device, pins its certificate and keeps the session.
Firmware and terminal both published as source.
Two halves
Use either one alone, or the pair.
BaudHound
The device. An ESP32-S3 on the target's UART, with its own WiFi network, a web console, telnet, TLS and USB, and baud detection.
BaudHoundTerm
The console. Saved sessions for SSH, telnet, serial, local shells, VNC and cameras, with a credential vault, logging and an AI agent.
Used together
Press the BaudHound button, pick the device, and its console opens in a tab set up for it, over TLS.
