Add support for a non interactive mode which allows other application to pipe data to tio which then forwards the data to the connected serial device. Non ineractive means that tio does not react to interactive key commands in the incoming stream. This allows users to pipe binary data directly to the connected serial device. Example use: $ cat commands.txt | tio /dev/ttyUSB0
