CRLF Mode

See more FTP Examples

The CrlfMode property applies when downloading files in ASCII mode. If CrlfMode is set to 0 (the default), then the ASCII transfer happens normally without alteration. A value of 1 converts all line endings to CR+ LF. A value of 2 converts all line endings to LF-only. A value of 3 converts all line endings to CR-only. Swift
