I have a CNC machine tool dating from the mid eighties which is controlled using RS232 from a PC running windows 7 and I've never seen any problems. I can't remember what the physical interface is at the PC end, but I have an idea it's a card with a couple of serial ports rather than a USB to serial convertor. I'll check.

How about scoping the output from the GPS device to get an idea of speed although syncing might be difficult?
