tio is a simple TTY terminal application which features a straightforward commandline interface to easily connect to TTY devices for basic input/output.

It was created because the author needed a simple no-nonsense TTY terminal application to easily connect to various terminal TTY devices.

The commandline interface is straightforward as reflected in the output from 'tio --help':

    Usage: tio [<options>] <tty-device>

    See the man page for list of supported mapping flags.

    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 features full bash autocompletion support.

Tio also supports various key commands. Press ctrl-t ? to list the available key commands.

See the tio man page for more details.
