The console mirror feature enables on-demand recording of serial console traffic for a specific console line. It mirrors RX and TX data streams observed by the per-line console proxy to secure local recording files and can optionally display the mirrored stream live to the mirror user. This helps diagnose serial console issues without taking over or interrupting the active console session.
