Serial Console

Many embedded systems and industrial devices expose a serial console, usually reached with a USB cable and a desktop tool such as PuTTY or minicom.

This app brings that console to the browser: connect to a device's serial port over the network, from any computer or phone, with nothing to install on your side.

It is useful for reading boot logs, opening maintenance shells and sending commands to equipment that talks over a serial line. Made for technicians, developers and field deployments where physical access is limited.

Version 1.1.0 comes with a real terminal emulator. Colours, cursor movement and full-screen programs such as nano, vi, top or menuconfig display as they do in a desktop terminal, and boxes and logos made of characters line up. The whole keyboard works, including arrows, function keys and Ctrl combinations, with copy and paste and 10,000 lines of scrollback.

Pick the serial port from the list the device reports, set the baud rate, data bits, parity and stop bits, and press Connect. Your settings are remembered for the next visit. You can choose what the Enter key sends (CR, LF or CR+LF), read text as UTF-8 or as raw 8-bit, turn on local echo for equipment that does not echo, clear the screen and save the session to a log file. A "Send size" button tells the remote shell how big your terminal is, something a serial line cannot do by itself.

The page adapts to phones, and the console also works through Orbit Connect remote access.

The app runs behind the device login and opens one session at a time, so two people never fight over the same port.

After installation, open the device portal at http://<device_ip> and select the Serial Console icon.
