MSP430 USB CDC Driver - Flow Control

Other Parts Discussed in Thread: MSP430F5510

I have a MSP430F5510 based design that communicates with the USB bus in CDC/ACM mode.

While writing the serial interface code, the behavior of the application doesn't seem to change if I keep flow control ON or OFF while initializing the serial port.

My question is how does the Linux driver handle Flow control with the application. Does the driver buffer the data that application sends till the processor is ready to receive data? or does it drop the data if flow control is not used in the application?

Thanks.
