I have $exccmd = 'c:\gpsmancer\gpsbabel\gpsbabel.exe -i garmin,get_posn -f com4 -o kml -F con: ' ; in my code. When the statement is executed on the winXP command box, the return is a series of xml lines in the general form <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://earth.google.com/kml/2.1"; ... When I execute $output = passthru($exccmd, $return); There is no output returned There is no output when the exec() statement is executed as well. The passthru() and exec() commands work as expected in other places in the code when other commands are executed. Perhaps it's a Gpsbabel thing? gpsbabel works correctly when the output goes to a file.
