Value Range:

0- DISABLED (default)

Only relevant when the ser.mode= 0- PL_SER_MODE_UART and ser.interface= 0- PL_SER_SI_FULLDUPLEX (full-duplex). Flow control uses two serial port lines- RTS and CTS- to regulate the flow of data between the serial port of your device and another ("attached") serial device.

Depending on your platform, you may be allowed to remap RTS and CTS lines to other I/O pins of the device through the ser.rtsmap and ser.ctsmap properties. Also, you may be required to configure RTS and CTS lines as an input and output through the io.enabled property of the io object. For more information, refer to your device's platform documentation (for example, EM1000's is here).

When the flow control is disabled both RTS and CTS lines are not used by the serial port and become regular I/O lines that can be controlled through the io object.
