What Is Flow Control And How Does It Work?

Hardware flow control on the SoundStructure device requires two additional handshaking signals, CTS and

RTS, in the RS-232 cable to ensure data is received before additional data is sent. This prevents the serial

port from dropping data due to not being ready for new data. Flow control literally controls the flow of data

between two serial devices.

If hardware flow control is used - and it is recommended that you use flow control on data rates above 9600

baud - then it should be enabled on both the SoundStructure device and the device that is connected to the

SoundStructure device.

Hardware flow control may be enabled on a SoundStructure device with the API command

set ser_flow 1 hw

and may be removed with the command

set ser_flow 1 none

where 1 is the device ID.
