FTP Automatic Post-Connect Commands

Demonstrates the AutoFeat, AutoSyst, AutoOptsUtf8, and AutoXcrc properties, which control commands Chilkat issues automatically around connecting and transferring.

Background: Chilkat normally probes and adapts to a server on its own: AutoFeat discovers capabilities with FEAT, AutoSyst learns the OS type to parse legacy listings, and AutoOptsUtf8 enables UTF-8 filenames when the server advertises it. These are on by default and rarely worth changing. AutoXcrc is the exception worth enabling deliberately — it verifies each upload with the server's XCRC checksum, catching corruption automatically where supported.

    //  AutoSyst (default true): automatically send SYST after login to learn the server OS type.

    //  AutoOptsUtf8 (default true): send OPTS UTF8 ON when the FEAT response advertises UTF8.
    ftp.AutoOptsUtf8 = true;

    //  AutoXcrc (default false): request an XCRC checksum after each upload and treat a mismatch as
    //  a failure, giving automatic post-upload verification where the server supports XCRC.

    //  Normally you would not hard-code the password in source.  You should instead obtain it
    //  from an interactive prompt, environment variable, or a secrets vault.
