I am trying to recover a machine that has a Gould Gettys 410 Position Controller (circa 1988) communicating with a Xycom 4810ER via Serial Communication out of the Programmer Port on the Gould. The Xycom Terminal lost its memory. I need to set up the Com Protocols in the Xycom to match the Gould. Does anyone know the correct Protocols for the 410? I have a 480 Programmer that if I disconnect the Serial Cable from the Xycom, I simply plug in the 480 and communication is established.

Any Help is greatly appreciated since there are so many permutations for the Port Settings
