I am using three Radio Shack converters, which had Vista drivers on their 
CD's which seem to work with Windows 7 on this laptop.  I think they use the 
Prolific chipset.  One USB-to-serial converter drives an Enabling Technology 
RB40 embosser from Duxbury.  Another drives the Rotor-EZ controller board 
from Idiom Press, from N1MM's rotor control program.  The third controls the 
Yaesu FT950 from Ham Radio Deluxe or N1MM.

FTDI chipsets have a reputation for being more bullet-proof.  Some folks on 
the FT950 list swear by cables they buy from W4RT Systems.  I think that 
finding usable drivers can be the most vexing problem.  Some FT950 owners 
also insist on putting multi-RS232 adapters into the desktops they 
customize, so clearly there are many approaches which can work for you.

Subject: USB to serial converters

I'm using Windows 7 so don't have any serial ports on my computer. I was
wondering if anyone knows of any specific converter that works with the
Kenwood ts2000 and thf-6a. Any help would be appreciated.
