Details

A warning note icon. This property is only available on selected platforms. For more information, please refer to your device's platform documentation (for example, the EM1000's is here).

The default value of this property is different for each serial port. See the list of pl_int_num constants in the platform specifications — it shows default values as well.

Absolutely any I/O line can be selected by this property, as long as this line is not occupied by some other function. The property value can only be changed when the port is closed (ser.enabled = 0 — NO).

On certain platforms, you may need to configure the line as output. This is done through the io.enabled property of the io. object.
