We have been using driver V1.30 recently, and just love it. It works like a= =20 charm on windows 7 64 bit too. Here is the prolific USB to RS232 cable we use most of the time (it has thr= ee=20 LEDs, Power, TX and RX, very user friendly): http://www.auelectronics.com/products/cbl-usb-232.html Funny N.

Unfortunately I am not organized enough to have version details, so far it's whenever I use a new laptop I seem to have to do a trial and error thing. Just a couple of weeks ago I got a netbook running Win7 and the driver from Prolific did not work, so I found an older driver on the net and it worked, but I did not do a thorough test(and not with hyperterminal). I don't have it with me but tonight I will look at it and see which version of the driver I used, and maybe I will have a link to it, too.
