I have a Delta20 and am attempting to drip a program to it through the RS232C. I am attemping this though a cable that is USB to DB9toDB25 into the controler. I can load and unload programs all day with this but run into a parody error when trying to drip a large program. I can drip a small program, but I believe the buffer is large enough to hold the whole program. I suspect the controler is not giving the external computer the on/off signals to send the data. Does anyone know of a place I can get a proven USB to RS232c for this application or if you have any other idea what is going on
DNC4U? Possibly? I have just been reading about it hoping to do the same thing.
