 * <li>remote.port - The port on the FTP server to connect to. Defaults to FTP default.</li>
 * <li>transfer.mode - The type of transfer for this connection ('ascii', 'binary'). Defaults to 'binary'</li>
 * <li>connection.mode - The type of FTP connection to make ('active_local', 'passive_local'). Defaults to 'active_local'. In active_local the server initiates 'data connections' to the client
 * where in passive_local the client initiates 'data connections' to the server.</li>
 * <li>network.data.timeout - Default is 0. Sets the timeout in milliseconds for waiting to establish a new 'data connection' (not a control connection) when in ACTIVE_LOCAL mode. Also, this
 * establishes the amount of time to wait on read calls on the data connection in either mode. A value of zero means do not timeout. Users should probably set a value here unless using very
 * reliable communications links or else risk indefinite hangs that require a restart.</li>
 * <li>network.socket.timeout - Default is 0. Sets the timeout in milliseconds to use when creating a new control channel socket and also a timeout to set when reading from a control socket. A
 * value of zero means do not timeout. Users should probably set a value here unless using very reliable communications links or else risk indefinite hangs that require a restart.</li>
