Wow Don, my head is spinning......I think you covered it all....
USB to serial ports tend to be more susceptible to RFI.......
That was experience with the Belkin model. Otherwise it was fine for rig
control.

I have a TS-2000 and a laptop computer with only one 9-pin
> port. These two are connected via their 9-pin ports so that Writelog can
read the operating frequency and mode. I would like to

the Writelog CD? Is this a direct computer to rig hardware

have only USB and LPT ports available. Adapter cables may
