ABSTRACT
AEA.TXT           Details of differences with the AEA PK-232 TNC's
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


AEA TNC's have a different command set than the TAPR-2 standard.  APRS tries 
to set up your TNC for simple display of monitored packets as follows:  

W3XYZ>APRS,DIGI1*,DIGI2:............

therefore it turns off extra linefeeds, timestamps, and other special headers:

    TAPR COMMAND   AEA PK-232 CMD   Function
    ------------   --------------   -------------------------------
    MON ON         MON 1 (2 for DX) Sets up MONITOR function
    SCR 0          ACRDISP 0        Turns off screen length limiter
    LFADD off      ALFP off         Turns off outgoing Linefeeds
    AUTOLF off     ALFD off         Turns off incomming LineFeeds
    MST off        MST off          Turns Time Stamp off
    HEA off        HEA off          Turns Header line off
                   MDigi ON         So that you see packets that are
                                    digipeated through you! (via RELAY)

If you have your PK232 battry removed for PACKRAT,  you must first use the OPS
COMM command to setup your TNC autobaud.  Hit several ***'s until the TNC res-
ponds.  Then hit ESC to return to APRS. In APRS, hit alt-S and T to initialize
the TNC.  Also AEA dualport TNCs toggle HF/VHF, so they will not switch bands.
Some programs leave the AEA TNC in HOST mode.   This will not work with  APRS!
Make your TNC work with any dumb-terminal program, and it will work with APRS!
