Tio -- an excellent serial terminal

I’ve long used screen for a serial terminal on Linux workstations, but its overkill, and having to nest command modes gets confusing if run inside tmux. So, I’m delighted to find tio (thanks @khem):

It does smart things like:

  • assume 115200 baud (used 99% of the time for serial consoles)
  • reconnects if a device is disconnected then reconnected
  • plays nicely with tmux

To start, it’s as easy as:

tio /dev/ttyUSB0

To exit: ctrl-t q

You can type ctrl-t ? to see a list of available commands.
