AutoIt

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 True): automatically send FEAT to discover server capabilities.
$oFtp.AutoFeat = True

;  AutoSyst (default True): automatically send SYST after login to learn the server OS type.
$oFtp.AutoSyst = True

;  AutoOptsUtf8 (default True): send OPTS UTF8 ON when the FEAT response advertises UTF8.
$oFtp.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.
$oFtp.AutoXcrc = True

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