Get the position periodically:



    #!/usr/bin/perl
    use GPS::NMEA;
   
    my $gps = GPS::NMEA->new(Port => /dev/cuaa0, # or COM5: or /dev/ttyS0
                             Baud => 4800);
    while(1) {
        my($ns,$lat,$ew,$lon) = $gps->get_position;
        print "($ns,$lat,$ew,$lon)\n";
    }



Get the internal NMEA dump:



    #!/usr/bin/perl
    use GPS::NMEA;
    use Data::Dumper;
   
    my $gps = GPS::NMEA->new(Port => /dev/cuaa0, # or COM5: or /dev/ttyS0
                             Baud => 4800);
    while(1) {
        $gps->parse;
   
        # Dump internal NMEA data:
        $gps->nmea_data_dump;
   
        # Alternative to look at the internal NMEA data:
        require Data::Dumper;
        print Data::Dumper->new([$gps->{NMEADATA}],[])->Indent(1)->Useqq(1)->Dump;
    }
