What is acm?
This read-only setting (na, on, or off) reports whether Adaptive Coding and Modulation is enabled on this radio interface, letting the link automatically trade modulation order for reliability as conditions change. Admins check this to understand why rxModulationIndex/txModulationIndex might be shifting on their own during weather events.
Examples
