Synopsis:
   The PASV command requests "passive mode" transfer.

Syntax:
   PASV

Description:
   Normal FTP relies on the server being able to initiate a data
   connection on TCP port 20 of the client host.  This however may
   not be possible if the client is located behind a firewall or
   connection multiplexer.

   Passive mode opens the data connection on the server instead,
   informs the client of the IP adress and port number, then waits
   for the client to connect.

   The PASV command must be sent before each data transfer.
