NAME
tio - a simple serial device I/O tool
Disable automatic connect.
- 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.
+ 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 an established connection is lost.
Redirect I/O to socket.
- Any input from clients connected to the socket is sent on the serial port as if entered at the terminal where tio is running (except that ctrl-t sequences are not recognized), and any input from the serial port is multiplexed to the terminal and all connected
- clients.
+ Any input from clients connected to the socket is sent on the serial port as if entered at the terminal where tio is running (except that ctrl-t sequences are not recognized), and any input from the serial port is multiplexed to the
+ terminal and all connected clients.
Sockets remain open while the serial port is disconnected, and writes will block.
CONFIGURATION FILE
Options can be set via configuration file using the INI format. tio uses the configuration file first found in the following locations in the order listed:
- $XDG_CONFIG_HOME/tio/tiorc
+ $XDG_CONFIG_HOME/tio/config
- $HOME/.config/tio/tiorc
+ $HOME/.config/tio/config
- $HOME/.tiorc
+ $HOME/.tioconfig
Labels can be used to group settings into named sub-configurations which can be activated from the command-line when starting tio.
