The SerialPortOpenModeEnum Enum

The SerialPortOpenModeEnum Enum

The SerialPortOpenModeEnum enum defines possible read modes of a serial port on the Raspberry Pi.

Blocking refers to to the way the serial port code deals with a request to read more data than is present in the input queue. If the port is in block mode and more data is requested than is present, then the call will wait until the required amount of data arrives. In OPEN_NONBLOCK mode the port will just return what it has.
