This tool allows you to share/access your serial terminal over the internet.
Based on xterm.js, localtunnel.

Works on:
Linux,
Windows,
MacOS

Features:

• Automatic tunneling from local machine to a public-accessible link
• Multi-user access
• Simple password-based authentication (with multiple credentials)
• Read-only access for specific users
• ANSI escape codes support: colors, mouse, window resize, window title
• Bonus: share your OS shell. Just specify shell instead of serial port

Example

$ serial-server /dev/ttyACM0 --baud=115200 --auth=vova:MyPaSS --tunnel=vsh-device01
Server listening on 0.0.0.0:5123
Preparing your tunnel...
Opened port /dev/ttyACM0,115200
Tunnel link: https://vsh-device01.localtunnel.me

Visit the provided tunnel link. It will ask for the password, then present you with a remote terminal:

More examples

Start OS shell server, allow multiple guests to connect with read-only access:

$ serial-server shell --auth=vova:MyPaSS --auth=guest --readonly=guest --tunnel=vsh-shell

Non-authenticated access is always provided in read-only mode:

$ serial-server /dev/ttyACM0 --tunnel=vsh-device01
