Flow Control

The flow control field is used when sending or receiving serial data.

• None disables the Xon/Xoff function.

• Xon/Xoff lets the Test Set “talk/listen” to the transceiver to alter

the rate of the data being sent.

• Hardware uses the serial port’s RTS and CTS lines to transfer data

at high baud rates.

NOTE Do not turn flow control on (set Flow Cntl to Hardware

in the I/O CONFIGURE screen) for the serial port until

you have a device attached to the port that can respond to

the flow control communications.

Example: You have a printer attached to SERIAL PORT 9.

Before you run any IBASIC software (for example, the

RFTOOLS program), you must make sure that the printer

is properly connected and that its power is turned on.

Operating Considerations

This setting is retained when the instrument is turned off.

Baud rates of 38400 and above must use Hardware flow control.
