2. The language of RFC 354 reads that it is recommended for
hosts to implement the default parameters. The sense of the
word recommended should be taken as required. Thus the
required minimum implementations for FTP servers is:
Type - ASCII (8-bit bytes)
Mode - Stream
Structure - File
Commands - RETR, STOR, USER (and PASS), SOCK and BYE
3. The "Print File-ASCII" and "EBCIDIC Print File" types are
incorrectly specified (pages 10 and 11, RFC 354). The real
problem with print files is of ASA (Fortran) vertical format
control. Instead of the two print file types, there should
really be three types as described below:
BCDIC - The sender transfers data using the EBCDIC
character code and 8-bit transfer byte size.
The _CRLF_ convention is used for vertical format
control. This type will be used for efficient
transfer of EBCDIC files between systems which
use EBCDIC for their internal character
representation.
