I have a Fadal mill (standard cnc88 fadal control) and a Hyundai lathe with a Siemans 840c. control) My desktop died so I bought a new laptop for cadcam and transmitting NC files to the machines.

In the past with XP I had no problems communicating with the USB to Serial adapter. Vista and Win7 don't work with my communication software. (NCFadal and Wincomm) Does anyone have an inexpensive way to make this work? These machines are for hobbies so cost is a big issue.

I repair CNC's for a living and found these for a song. Put them in my garage for bikes and hot rod stuff. Alot of fun when they work.

This is second PC that died so I want to upgrade to something more reliable. When they only get turned on every couple of months I really can't afford to spend $300 every time I want to load a new NC file.

Any help would be really appreaciated.
