Here I am again, trying to communicate with a Fanuc M15. I've got my com program set to 4800,7,E,2, xon/xof and can't get a response from the serial port before it times out. I've used from
2400 to 9600 baud; 8,7 bits, even, odd, and no parity and 2, 1.5 and 1 stop bits. This is the same port I could talk to a couple of weeks ago. I've run a loop back test on the computer port and the cable. I have a port monitor that says the computer is putting out data until it doesn't get a response from the Fanuc. The control is set using the program>program>program>read>(prog #)>number>exec sequence of soft keys. The read indicator on the screen is blinking but goes to a bgXXX error-mismatch device or other bgXXX error. I'm at my wits end trying to figure out what's wrong. Could someone make a suggestion as to where to look or what may be wrong?
