======APRS Message Server Help======
==== A ====
<code>
The /A command lists the APRS announcements received by the router
They are listed in alphabetical order by sender.
Announcements have a destination address of the form BLNxCCCCC where
x represents a single non-digit and CCCCC represents the category (up
to 5 characters). They are transmitted once per hour for 4 days, and
incoming announcements are retained for 4 days after last reception.
</code>
==== B ====
<code>
The /B command lists the APRS bulletins received by the router.  They
are listed in alphabetical order by sender.
Bulletins have a destination address of the form BLN#CCCCC where #
represents a single digit (0-9) and CCCCC represents the category
(up to 5 characters).  They are transmitted every 20 minutes for
4 hours, and incoming bulletins are retained for 4 hours after last
reception.
</code>
==== C ====
<code>
The /C (Cancel) command is used to cancel re-transmission of outgoing
messages originated by yourself, e.g. "/C 12345" will cancel message
number 12345.  Entering /C by itself will list the messages which may
be cancelled.
</code>
==== D ====
<code>
The /D (Directs) command gives a brief list of the stations heard
directly (i.e. not via digipeaters or 3rd party networks).
</code>
==== H ====
<code>
The APRS messaging system accepts the following commands:
         /A[nnouncements]    Show announcements
         /B[ulletins]        Show bulletins
         /C[ancel] [#]       List / cancel unacked message(s)
         /D[irects]          Show directly heard stations
         /H[elp] [cmd]       Display command help
         /Monitor [on|off]   Query / set traffic Monitor mode
         /Q[uit]             Quit (exit)
         /T[arget] [call]    Query / set target for msg
         /U[iview] [on|off]  Query / set UI-View mode
         /V[ia] [digis]      Query / set digipeater path
         /X                  Exit
Commands and arguments are case-insensitive, and only the first
letter is required, thus "/H" and "/help" are equally valid.
To get more help on any command type "/H <command>", e.g. "/H /T".
For a full list of help topics enter "/H *"

==== M ====
<code>
The /M (Monitor) command controls message traffic monitoring as follows:
   /M        Displays current monitor state (on or off)
   /M ON     Enables monitoring of messages not addressed to you.
   /M OFF    Only messages addressed to yourself will be received (default).
</code>
==== Q ====
<code>
/Q (Quit) quits the APRS messaging session and returns you to the router's
          main prompt. The /x (exit) command performs the same function.
</code>
==== T ====
<code>
The /T (Target) command queries or sets the message target as follows:
   /T             Reports current target.
   /T <call>      Sets target to <call>, and sets "message" mode.
   /T BLN#xxxxx   (# = 0-9) Sets "bulletin" mode, category xxxxx
   /T BLN@xxxxx   (@ = non-digit) Sets "announcement" category xxxxx
   /T .           Clears target. Any punctuation character will do.
Once set, the target remains in force until cleared or a new one is set.
</code>
==== U ====
<code>
The /U (UI-View) command displays and sets "UI-View" messaging mode
as follows:
   /U        Reports current mode
   /U ON     Turns UI-View mode on. Outgoing msgs use UI-View format.
   /U OFF    Turns UI-View mode off. Outgoing msgs use APRS format.
The default mode is "off".  In either mode, both types of message can be
received.  UI-View messages will display with a tilde (~) between the
message and its ID, whereas APRS-format messages will display with a
curly opening bracket ({) if a message ID was supplied.
</code>
==== V ====
<code>
The /V (Via) command queries or sets the digipeater path for outgoing
messages as follows:
   /V               Display current path
   /V RELAY,WIDE    Set path to RELAY,WIDE
   /V .             Clear path (no digipeaters)
The path remains in force until cleared or a new path is specified.
</code>
==== X ====
<code>
/X (eXit) quits the APRS messaging session and returns you to the router's
	  main prompt. The /q (quit) command performs the same function.
