You are giving the port a valid input so it's actually looking for DTMF, correct? Otherwise, depending on the logic used in the RC-210 it may not even look for DTMF. Unless the firmware has changed significantly in the past 4 years, the RC-210 needs some sort of logic input on a port (COS or CTCSS) in order to watch for DTMF on that port. So if you're just feeding DTMF straight into a port, it needs to be active in order to respond to the DTMF. Bob NO6B
