 Using serial devices by ID ensures that tio automatically reconnects to the
 correct serial device if it is disconnected and then reconnected.
 
+If no serial device by ID is available it is also possible to connect via
+topology ID (TID):
+```
+$ tio bCC2
+```
+The TID is unique and will stay the same as long as your USB serial port device
+plugs into the same USB topology (same ports, same hubs, etc.). This way tio
+will successfully reconnect to the same device when reconnected.

 List available serial devices:
