Salut, bonsoir,
les quatre premiers nombres passés en arguments de "PORT" correspondent 
à l'adresse IP (du client?),
et les deux suivants (4,110) au port TCP utilisé pour la connexion. 
Dans ton cas, en binaire 4,110 me
semble donner: 10001101110, soit, 1134 en décimal... ça me semble élevé 
comme n° de port, mais bon.
ci-joint de la doc trouvée sur :
http://www.w3.org/Protocols/rfc959/A1_PageStructure.html
portant sur cette question de la commande PORT:

DATA PORT (PORT)


           The argument is a HOST-PORT specification for the data port
           to be used in data connection.  There are defaults for both
           the user and server data ports, and under normal
           circumstances this command and its reply are not needed.  If
           this command is used, the argument is the concatenation of a
           32-bit internet host address and a 16-bit TCP port address.
           This address information is broken into 8-bit fields and the
           value of each field is transmitted as a decimal number (in
           character string representation).  The fields are separated
           by commas.  A port command would be:

              PORT h1,h2,h3,h4,p1,p2

           where h1 is the high order 8 bits of the internet host
           address.
Et ci-dessous les codes de retour des commandes FTP pour éclairer tes messages d'erreur:

 110 Restart marker reply.
            In this case, the text is exact and not left to the
            particular implementation; it must read:
                 MARK yyyy = mmmm
            Where yyyy is User-process data stream marker, and mmmm
            server's equivalent marker (note the spaces between markers
            and "=").
        120 Service ready in nnn minutes.
        125 Data connection already open; transfer starting.
        150 File status okay; about to open data connection.

voilà, je ne te suis pas d'une grande aide pratique, mais ce sera 
peut-être un point de départ...
