I have improved my exception handling and discover that on the office system after connection I get the message "entering extended passive mode" and I have no idea as to how to proceed. The office has 2 data inputs ATT & TMobile. My code does work as intended when I switch to ATT DSL but we had elected to make TMobile the primary as it's lots faster. Not my decision. I'm just plain lost.
I read that the ftp server expects me to issue an EPSV command and create a data socket and connect it to the IP address of the control connection and port number indicated in the EPSV reply. (1) I don't understand what I should be doing and (2) why is the server responding differently if I use TMobile or ATT? The server is the same in both cases and in the case when I use the program from home (again a different ISP).
