DSR (data-set-ready)

RTS (request-to-send)

CTS (clear-to-send)

CD (carrier-detect)

For RS-232 specifications, DTR and RTS are for output signals and

can be toggled on and off simply by double-clicking legends (such as

DTR, DSR, RTS, CTS, CD) under the red/green marks. But if your are

using RTS/CTS for flow control to run the test, you will see the RTS

mark appear as black. This indicates that the RTS can no longer be

toggled on/off since it is now controlled by driver itself.

A black mark represents the function is controlled by driver itself

and therefore not controllable by software utility.

On the Message Logo area, you can see the relevant messages about

the port(s) you have selected.

For information about specific messages in this area, please refer to

Section 4.4, Messages on the Status Bar and Message Logo area.

The Tx Slide Bar allows you to check the overall system loading. You

can adjust the transmission rate of your port(s) from 0% to 100%. Just

drag the slide button along the groove to adjust the transmission rate.
