MultiNet TCP/IP packages on VMS. ISTR that there was a mode available
in the FTP client for one or both of these that I could use with other
hosts where records were used (VMS, TOPS, etc) so that I could
transfer files with the record structure intact. Much like switching
between ASCII and BINARY mode, but I can't recall what the command
was. (TENEX? STRUCT?)
Inter mainframe incompatibilities were part of FTP from very early
days,
RFC 571 (1973( brought up the TENEX problem and RFC 683 (1975)
proposed a solution. How simple the matter of codes has become is
evidenced by the listing of the various datatypes in RFC 114 (about
30 of them).
