* information. The data will be transferred in ASCII or
* EBCDIC type over the data connection as valid pathname
* strings separated by <CRLF> or <NL>. (Again the user must
* ensure that the TYPE is correct.) This command is intended
* to return information that can be used by a program to
* further process the files automatically. For example, in
* the implementation of a "multiple get" function.
