Javascript Socket Obj and Port 21

Question

I'm just trying to open a socket connection to an ftp server
on port 21. I've read that people have had success over flex/flash,
but I haven't been able to connect to port 21 with Javascript and
there are no events or error messages associated with trying.
I'd just like to know if its currently possible.

Answer 1

Yes, you can use the Socket class to connect to an FTP server
in JavaScript:
var socket = new air.Socket("ftp.cs.berkeley.edu", 21);
socket.addEventListener(air.Event.CONNECT, connected);
socket.addEventListener(air.ProgressEvent.SOCKET_DATA,
dataHandler);
socket.addEventListener(air.IOErrorEvent.IO_ERROR,
errorHandler);
socket.addEventListener(air.SecurityErrorEvent.SECURITY_ERROR,
securityErrorHandler);
