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.

//  These auto-* properties control commands Chilkat sends automatically after connecting.  They
//  are on/off by default as noted, and are rarely changed.

//  AutoFeat (default .T.): automatically send FEAT to discover server capabilities.
loFtp.AutoFeat = .T.

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

//  AutoOptsUtf8 (default .T.): send OPTS UTF8 ON when the FEAT response advertises UTF8.
loFtp.AutoOptsUtf8 = .T.

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

//  Normally you would not hard-code the password in source.  You should instead obtain it
