Subject: NMEA , request for real live sample

Dear All ...
Is there any easier to understand sample of ruby nmea parser (
http://rubyforge.org/projects/nmea/ ) ??

I need to parse NMEA , and re format it to YAML.
 I tried to :

---START---
require 'serialport'
        require 'nmea'
        @sp = SerialPort.open("/dev/ttyS1", 4800, 8, 1,
SerialPort::NONE)
        @handler = NMEAHandler.new
        while(@sentence = @sp.gets) do
          puts NMEA.scan(@sentence, @handler)
        end
---STOP---

but it only print "nil"

I thought that my system is not well wired, so I make a test using
miniterm.rb from the serialport library, and here is the result
---start---
[root@kannel test]# ruby ./miniterm.rb 1 4800 8 1
$GPRMC,135444,A,3815.4477,N,02349.5804,E,10412.9,243.3,090507,5,E,A*B
$GPRMC,135446,A,3810.5221,N,02344.4003,E,11501.1,219.6,090507,5,E,A*B
$GPRMC,135448,A,3803.9503,N,02341.4152,E,12561.9,199.7,090507,5,E,A*B
---stop----

Note : My test system is
1. GPS Feed : Using a PC running GPSFeed+
2. Ruby on the other Linux PC
3. The two PC is connected via a null-modem cable.

Sincerely
