parameter allows you to select the type of serial communication used.
You can choose the

option if you want the rate of data transmission to
match the rate at which it can be processed by the device. This enables the
computer and the Broadband Source to stop each other from transmitting
by sending a control character (Xoff). They will also be able to restart the
transmission by sending another control character (Xon). This is known as
a “software handshake”.
