Since I got my D700, I took the laptop out of the 
car and have not routeinly operated APRS laptop 
mobile in years.  So I'm beginnning to think you
are right that that format is the way it works when
live GPS data is coming in.  That is why APRS has 
the STATUS packet, so that is where you can put
your comment as to what you are doing.... bob

I'm still at a loss as to why I'm getting my comment overwritten on my posit 
packet. Both aprssig replies thought I must be sending my GPS directly out 
through my TNC.  This is not the case.  I'd still like help.

I am using two serial ports on my laptop (MS-Dos V6.00) but still have my posit 
text overwritten.  One serial port (COM1) is for the TNC (MFJ-1276) and the 
other serial port (COM2) is for the GPS (RS DigiTraveler). The APRSdos V863 must 
be involved since it is assigned the two serial ports during program start-up. 
I am using the default settings for APRSdos screen refresh and  GPS packet (30 
and 180 seconds).  Everything works fine except the posit text I enter is 
overwritten with something like:

GGA/NUL/APRS*/good GGA/A=0004880488

Thanks for taking another look at this,
