 | `string`   | String           | Channel for sending/receiving data as a string to/from the serial port. The channel will update its state to a StringType that is the data received from the serial port. A command sent to this channel will be sent out as data through the serial port. |
-| `binary`   | String           | Channel for sending/receiving data in Base64 format to/from the serial port. The channel will update its state to a StringType which is the string representation of a RawType that contains the data received from the serial port. A command sent to this channel must be encoded as the string representation of a RawType, e.g. `"data:application/octet-stream;base64 MjA7MDU7Q3Jlc3RhO0lEPTI4MDE7VEVNUD0yNTtIVU09NTU7QkFUPU9LOwo="` |
