New to me machine(Fadal VMC15): 1994/88HS/1405-A/422K ram. To run large programs, I bought an USB-interface box. I installed(right inside of the Control Panel Box(with amps, etc.) so as to eliminate cable issues. My controller can see my USB removable stick and the various programs on it. When I use the "DNC" command to run a program, all is good for the first 100-to-150 lines of the program. The spindle stops moving(while engaged with "NOT-work piece", as I'm testing "Cutting air")and the controller says "RS232 error" and other attempts says "DNC Error". My baud rate is 19,200. [When I first installed my USB-interface box, I ran the 3-meter cord from Control Box to Controller and worked my way through the various baud rates(making sure USB-interface box's baud equaled controller's baud rate)]
Kinda running out of things to try, okay, I did run out of things so any help would be greatly appreciated.

check your grounding. I had a lot of problems with the same error in my old shop. In the new shop all the issues went away with a better electrical system.
Also double check the controller and you USB interface have matched communication parameters
