[DXLog.net - Support] Interlock, any message?

[Silvio IZ5DIY]

When Software Interlock is enabled, is there any message (or indication)
that a station is "locking" or "locked by"?

In my actual test (rtty contest) when first station is on tx and second
station is trying to transmit (hitting F1 per example) it just doesn't
transmit but I can't see any messages; so the operator could think it just
doesn't work, and don't know who is transmitting or/and when tx slot is
free.

I haven't found any indication on online docs.
