NAME
     xastir_udp_client - send simple messages to xastir for APRS(tm) network.

SYNOPSIS
     xastir_udp_client	<hostname>  <port>  <callsign>	<passcode>  {-identify |
     [-to_rf] <message>}

DESCRIPTION
     xastir_udp_client sends packets into the UDP listening port of  an  enabled
     xastir instance.

EXAMPLES
      xastir_udp_client  localhost  2023 <callsign> <passcode> "APRS Packet Goes
     Here"

     Currently that will inject the packet into Xastir's decoding  routines  and
     send  it to any TCP-connected clients. It will also igate it to the INET if
     you have igating enabled.	It will send the packet  out  the  RF  ports  as
     third-party  packets  only  if you add the "-to_rf" flag after the passcode
     like this:

      xastir_udp_client  localhost  2023  <callsign>  <passcode>  -to_rf   "APRS
     Packet"

     The UDP client is useful for generating and injecting APRS packets from ex-
     ternal  scripts.	It  can also be used to fetch the callsign of the remote
     xastir server by using the -identify flag:

      xastir_udp_client localhost 2023 <callsign> <passcode> -identify

NOTES
     This is a very simple utility that provides no validation of  message  con-
     tent.   The text passed as the last argument is directly injected into Xas-
     tir's incoming data stream and processed exactly as if it had come out of a
     TNC.

     As such, the text passed to it as "APRS Packet" must  be  a  complete  APRS
     packet,  including FROM and TO call signs, not simply the payload.  Thus to
     have it work properly, you should pass "MYCALL-0>APX219:payload goes  here"
     as  the string, not "payload goes here" (where obviously you should replace
     "MYCALL-0" with your own callsign and SSID).

     If the APRS payload provided is an object or item, and the  call  sign  and
     SSID provided in the packet header match Xastir's exactly, then Xastir will
     "adopt"  the object or item and treat it in the same manner as one that had
     been created in its own GUI --- that is, the object will  be  retransmitted
     with decaying intervals until deleted.  This can be useful if one wishes to
     create  objects  external to Xastir and have it take control over them, but
     can be a bit surprising if you weren't expecting it.  If you want	the  ob-
     jects  treated  as Xastir's own, use the same callsign and ssid for the ob-
     ject as the callsign/SSID that Xastir is using, and if you DON'T want that,
     use a different SSID.

     If Xastir's callsign is "MYCALL-0" then this invocation will create an  ob-
     ject that will be adopted and retransmitted:

       xastir_udp_client     localhost	  2023	  MYCALL-0    <passcode>    "MY-
     CALL-0>APX219,WIDE2-1:;foobar   *202111z3501.53N/10619.04W/"

     while this invocation will create an object that will only  be  transmitted
     once and not adopted:

       xastir_udp_client     localhost	  2023	  MYCALL-0    <passcode>    "MY-
     CALL-1>APX219,WIDE2-1:;foobar   *202111z3501.53N/10619.04W/"
