I have a Fanuc 10m that has worked perfectly for years, today when I tried to transfer a program with rs232 the machine will not read any incoming programs. All else on the machine seems to work properly as well. The strange part is, I can transfer a program back to the pc but its full of # signs and all sorts of other mumbo jumbo. Also the machine can still stop and start the Pc transfer from the control, but the control just will not read the incoming program.

No settings have been changed since the last time the machine worked.

Any thoughts on this?
