Pascal (Lazarus/Delphi)

Binary and ASCII FTP Transfer Modes

See more FTP Examples

The SetTypeBinary() and SetTypeAscii() method can be called to change the current transfer mode. The default transfer mode is binary. Once SetTypeAscii() or SetTypeBinary() is called, all subsequent transfers will occur in that mode. Pascal (Lazarus/Delphi)
