Thanks Ed,

I noticed this is the pin-out diagram for connecting my PC to program a 2856. Do you think its the same for connecting the 7480?
I will try it? Other than baud rate (2400), ICLID on and ring delay, is there any other programming?
One other note, the guys at Used-Phones are not sure this 7480 to 2856 has ever been done. Do you know if it has? Thanks Wade
