Link activity event trigger

I am successfully using the RPT_RXKEYED event to turn on and off the repeater's CTCSS encoder GPIO, but would also like to have the ability control the encoder when there is link activity. Is there an event trigger that is based on link rx activity?

Any "K" in the string means someone is keyed. In this case, 12345 is keying you up.

Where did you get that output from??? It was my understanding that the K key was never actually implemented anywhere thus the recent feature request: Implement of the K: Key IAX Text · Issue #130 · AllStarLink/ASL3 · GitHub

This is in ALINKS -> only the adjacent links send updates on change of event (to their direct neighbor).
"All" remote links are sent via a "slow boat" type of message that is propagated across connected nodes. The full link list does not share "state", only "mode" (Transmit, receive only, etc) and really can't tell you about any "realtime" information as the path too slow.

Ah, we do see K but for adjacent nodes only.
