While this makes property names easier to read, you can use any case you want when specifying property names. Additionally, you need use only enough letters to identify the property name uniquely, so you can abbreviate most property names. For example, you can configure the BaudRate property any of these ways. When you include property names in an M-file, you should use the full property name. Whenever you do not explicitly define a value for a property, then the default value is used.
All configurable properties have default values.
Note Your operating system provides default values for all serial port settings such as the baud rate. For example, the default value for the Parity property is none .
