I can not get my PC to comunicate with my Mazak VTC 41 with EIA (Yasnac MX-3 control) the manuals don't tell you much. I'm using windows terminal and in program key. I type in O-9999 , IN then send on terminal in a few seconds get TH parity error ! on the control screen, which does not help much if the is no list of errors in the manual. I am also using NCnet lite with no luck. I pretty sure the cables are good.

Any help would be great
