I have an Okuma MC-6VA CNC with a OSP5000M-G Control. I am trying to load and download to the CNC Control thru the RS-232 Serial Port. The programs going to the control from my laptop are losing characters along the way. The programs going to the laptop from the CNC control never lose any characters. I think this means the cable is ok. The slower the baud rate, the fewer characters are dropped but, I still lose 1 or 2 characters at the slowest speed. I need this to be perfect before I can turn to this over to the guys in the shop. My local distributor hasn't been much help.
