<hr><a name="_details"></a><h2>Detailed Description</h2>
A low-level, asynchronous FTP client based on RFC 959.
<p>
This class implements an FTP client. It allows the usual things done through FTP (uploading, downloading, dir-listing, etc), but at a very basic level.<p>
It may be a bit difficult to use, because it is so low level. It isn't as simple as "open ftp server, do dir-listing, upload file, close". All these functions are there, but they are asynchronuous. That is, they return immediately and don't wait for the end result. Nor can you queue commands: only one command can be executed at a time. This means you will have to do the high-level protocol stuff in your own class. On the other hand, it allows you to accurately follow the progress of your commands. Think of it as a wrapper around the FTP protocol itself, with some helper functions for the data transfers.<p>
With this class you have to make a distinction between 'commands' and 'state'. A command is just that: the user demands a certain action, and the class executes it. A string is sent to the FTP server to perform the command; if a data stream is needed that is opened as well.<p>
A command will cause various changes in the class that can be tracked through the ref StateChange signal. For example, uploading a file will cause the following states: SendingPort, WaitData, Transfer, ClosingData, Idle (or Failed). It reflects the various steps necessary by the FTP protocol to perform an actual filetransfer. It is up to the calling class to interpret these responses (most aren't really interesting to the user anyway).<p>
All commands will end in either "Idle" (== success) or "Failed" state. "Failed" indicates something went wrong; the <b>result</b> code from StateChange contains the numeric FTP response code that explains the error. "Idle", which also doubles as "Success", indicates completion of the command without error.<p>
Note that it is possible for a state to be set multiple times in a row. If, for example, Login was succesful and was followed by a "Change Dir" that also succeeds, StateChange will be emitted twice with state "Idle". This is okay; 2 commands were issued, so you get two <a class="el" href="class_c_f_t_p_client.html#l0">StateChange(Idle)</a> (possibly intermingled with other StateChange()s).<p>
Most commands listed below show a short state transition diagram, so you know what StateChange()s to expect.

Set transfer mode to passive.
<p>
Usually FTP transfers (both up- and downloads) are initiated by the server, after the command has been sent by the client. However, this does not always work (firewalls, braindead FTP implementations, etc) and the client has to do the work; this is called 'passive mode', and this function turns this mode on.<p>
Note: this function does not trigger a state change. </td>
