It is also possible to pipe data or command to the serial device. For example: Redirect device I/O to network file socket for remote tty sharing:
$ echo "ls -lah" | tio /dev/serial/by\-id/usb\-FTDI_TTL232R-3V3_FTGQVXBL\-if00\-port0 $ tio --socket inet:4444 /dev/ttyUSB0

Then, use netcat to connect to the shared tty session over network (assuming tio is hosted on IP 10.0.0.42):
$ nc -N 10.0.0.42 4444

Pipe data from file to the serial device:
