tio is a simple serial terminal tool which features a straightforward command-line interface to easily connect to TTY devices for basic I/O operations.
To make a simpler serial terminal tool for talking with TTY devices with less focus on classic terminal/modem features and more focus on the needs of embedded developers and hackers.
The command-line interface is straightforward as reflected in the output from 'tio --help':

In session, press ctrl-t q to quit.
The only option which requires a bit of elaboration is perhaps the
--no-autoconnect option.
By default tio automatically connects to the provided device if present. If
the device is not present, it will wait for it to appear and then connect. If
the connection is lost (eg. device is unplugged), it will wait for the device
to reappear and then reconnect. However, if the --no-autoconnect option is
provided, tio will exit if the device is not present or an established
connection is lost.
Tio supports various in session key commands. Press ctrl-t ? to list the available key commands.
Tio also features full bash autocompletion support and configuration via ~/.tiorc.
