 It is recommended to connect serial tty devices by id. For example:
 
-tio /dev/serial/by-id/usb-FTDI_TTL232R-3V3_FTGQVXBL-if00-port0
+tio /dev/serial/by\-id/usb\-FTDI_TTL232R-3V3_FTGQVXBL\-if00\-port0
 .PP
 Using serial devices by id ensures that tio automatically reconnects to the
 correct serial device if the device is disconnected and then reconnected.
