What is tio?

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

Usage

The commandline interface features the following options:

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

Options:
  -b, --baudrate <bps>        Baud rate (default: 115200)
  -d, --databits 5|6|7|8      Data bits (default: 8)
  -f, --flow hard|soft|none   Flow control (default: none)
  -s, --stopbits 1|2          Stop bits (default: 1)
  -p, --parity odd|even|none  Parity (default: none)
  -o, --output-delay <ms>     Output delay (default: 0)
  -n, --no-autoconnect        Disable automatic connect
  -l, --log <filename>        Log to file
  -l, --map <flags>           Map special characters
  -v, --version               Display version
  -h, --help                  Display 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 disconnects) 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 exit if an established connection is lost.

Features full bash autocompletion support.
