[Elecraft] Windows 7 64bit and USB to RS232 adapter

[Robert Redmon]

Dick,

I tried the driver on the Elecraft download page first. It loaded okay 
and windows recognized the adapter when I connected it, but it could not 
communicate with the K3 using the K3 Utility (latest release version). I 
will download and try v1.30 of the prolific driver when their download 
site is up and working properly again....It isn't right now.
