Push the boat out £2-98 p free PP , in the reviews one mentions
getting the driver from the Prolific web site , so that would point
to the right chip set , but comes with the mini cd as well

Tnx Graham, Jim es Co
Not all work as you say, depends what the application is, and some seem
expensive, maybe I should build an interface

Big arguments on the digital groups as to what type works etc
..
items that use the Prolific
chips , may be better , the latest driver is :-
Prolific 29/04/2011 2.0.16.166, I have one that cat links
the
ft897 to a usb port
Other usb/serial are provided by wch-cn , but the driver
(win-xp)
is data 03/06/2009
these run the pk232 and a t/r switch , seem to function ok ,
these came from amazon.com for £3 each , not quite plug and play ,
need to have driver installed , from mini cd or by web link
