Is this the exact string you're sending?  If so, it's not the right format.

It should be this:

N0RPM>xxxxxx;Pickup   *260424z4511.60N/09252.88WA

where xxxxxx is a string representing the software you're using to generate
the object.  Try something like APZRPM (APZ is the prefix for experimental
programs).  Avoid existing TOCALLS (see http://www.aprs.org/tocalls.txt).

Without the "N0RPM>" and the following TOCALL, Xastir isn't parsing the 
thing as an AX.25 frame --- that's why it simply exits with no further
output after the "start parsing" line.

HTH,
T.
