4.2.3. Flow Control
Flow Control
Setting Description
Default Setting (0) None
Options
l (0) None - No flow control CTS is active and de-asserts when buffering is 98%
full.
l Can pass XON/XOFF data but does not use it in any way.
l (1) RTS - Uses RTS/CTS (Request to Send/Clear to Send) for flow control.
l CTS performs the same way as in option (0) None.
l RTS must be activated for the radio to output data over the serial port.
l (2) DTR - Uses DTR/DSR (Data Terminal Ready/Data Set Ready) for flow
control.
Setup Terminal
Menu
(2) Set Baud Rate > (F) FlowControl
Description
l Specifies the hardware flow control for the data port on the radio.
l Flow control is the process of managing the speed data is transmitted to not
overwhelm the device receiving the transmission.
FREEWAVE Recommends: Use Flow Control if the Baud Rate is
higher than 9,600 in a narrow-band licensed network.
