No, it's not a "command" per se, it's just an APRS formatted
"killed" object packet that you can send into Xastir.  See the APRS
Spec for info.

Xastir has no specific commands that it is parsing from the server
port, other than the authentication string.

What the person suggested (and probably will work great) is
injecting a packet into Xastir as if that Xastir session itself sent
it.  The packet then goes through the normal received packet
processing.  It just so happens that Xastir "loops back" it's own
transmitted packets, and that's where an object/item kill actually
takes place, in the received packet decoding.  Good trick that.

You can use the same trick to have external programs/scripts inject
object/item packets into the server port.  Xastir will then take
over transmitting them as if you created them with the
mouse/keyboard.
