keeping command line communications open

[mrUser]

Correct me if I'm wrong but it seems you run a command line prompt and coreftp just opens, does the prompt, then closes. But what if I want my calling program to keep the coreftp program open and connected between upload and download requests for extended durations ready for duty? By connecting each time a upload or download is needed and disconnecting, the ftp server will flag and timeout the ip address or username if it does it too much in too short a time. So this could be a huge issue. Is there a way to keep it open and just communicate through a pipe or socket with coreftp while it remains connected?
