REG_REC packet receiving program for the TAPR PIC-E  N0QBH  1/2000

I've written a new application for the PIC-E that decodes AX25 packets heard
by the attached radio and sends the data in a TNC like format out the
GPS serial port at 4800 baud.  It was primarily designed to work with my
Palm III running PalmAPRS , allowing me to monitor the APRS freq and
plot most of the stations.  The storage has been tweaked as far as I know how
to, and as a result, the PIC-E can output up to 39 bytes of the info field as
well as the sender's and destination callsigns.
This is adequate to pass on the position data in most packets I've copied at
my QTH.  The serial out pin is still backwards, but this works fine with
the Palm HotSync cable which is also wired backwards :)
If you choose to use it with a regular pc and cable, you'll need a null modem
adaptor.  In testing here on my WInAPRS station, I've used the PIC-E in place 
of my TNC and find my screen as full as ever :)

PIC-E jumper configuration:
Jumper   #1  off
Jumper   #2  "N"  (pins 1&2)
Jumper   #3  off for most, on for some HT's
Jumper   #4  off to program, on to run
Jumper   #5  "RXD"  (pins 1&2)

Programming / use:
Assemble the program  pic_palm11.asm  with MPASM.EXE
Program it to your PIC-E with Picprog.exe
Connect the PIC-E to the radio as usual and the serial out to a Palmpilot or PC.
* Remember, data is on DB9 pin #3 and regular serial connection requires a
null modem adaptor be used.  Palmpilot with the Hotsync cable will attach
directly.  Serial out is 4800,8,N,1
Power up and watch the packets.
* Power up should be relatively clean.  I was able to get it to hang by causing
intermittants in the power supply.  If all is programmed and connected 
correctly, you should see a power up message   PIC-E packet decoder * N0QBH 
1999. Palm users should be in View Packet mode for this to be seen.

I configured my PalmAPRS as a PICO packet and told it to ignore the fact that it
can't talk to the tnc.  From there on it works fine.  Don't try to send anything
because it can't.  Maybe next version.
