22           Get the position periodically:
23
24               #!/usr/bin/perl
25               use GPS::NMEA;
26
27               my $gps = GPS::NMEA->new(Port => '/dev/cuaa0', # or COM5: or /dev/ttyS0
28                                        Baud => 4800);
29               while(1) {
30                   my($ns,$lat,$ew,$lon) = $gps->get_position;
31                   print "($ns,$lat,$ew,$lon)\n";
32               }
33
34           Get the internal NMEA dump:
35
36               #!/usr/bin/perl
37               use GPS::NMEA;
38               use Data::Dumper;
39
40               my $gps = GPS::NMEA->new(Port => '/dev/cuaa0', # or COM5: or /dev/ttyS0
41                                        Baud => 4800);
42               while(1) {
43                   $gps->parse;
44
45                   # Dump internal NMEA data:
46                   $gps->nmea_data_dump;
47
48                   # Alternative to look at the internal NMEA data:
49                   require Data::Dumper;
50                   print Data::Dumper->new([$gps->{NMEADATA}],[])->Indent(1)->Useqq(1)->Dump;
51               }
