Been using EZDNC for years but now notice random ? character shows up randomly in received parameter data from CNC. Will this damage our backup data files?
Control is Fanuc 16MC and PC OS is Windows 10.

That '?' would usually indicate a data error. That file probably won't go back in to the CNC without an error so you need to figure out what's causing it.
You said it's parameters that you're backing up. What happens when you punch out a large program? Does that also include '?' characters? If it does then is the '?' replacing some missing character(s) or is it between two good characters? Punching out a large program file might not be what you want to do but if you're a CNC programmer then looking at a CNC program might be easier for you to recognize if chars are being lost/replace by '?' etc.

Yes in a large program also it looks like the ? Is between characters it's random . It looks like it's added the original text is there just may be shifted over

You're picking up interference somewhere.
How long is your cable?
You said it's happening when backing up data from the CNC to the Computer. What about the other direction?. I mean when sending a big program 'to' the CNC does the Cnc throw an alarm? You didnt mention that so I'll assume its only happening in one direction (CNC to PC)
Can you open the end connectors and check the solder joints. Maybe even dab them with a hot soldering iron just to make sure they're solid.

Well I resolved it by setting the stop bits form the 7-2 even to 8-1even and left the machine at 7-2-even strange but it resolved the problem . This problem was on two Mori MV65s with consecutive serial numbers with Fanuc 16 controls .
