The MSS FTP Service provides access to MSS files for those systems that can not run the MSS DCS software. The MSS FTP Service provides only a way to retrieve MSS directory listings and to read and write MSS files. It does not provide MSS file management commands. It implements a large subset of the File Transfer Protocol as described by a number of Internet Engineering Task Force (IETF) standards and requests for comments (RFCs), along with MSS specific extensions.

In this documentation, there will be references to commands sent on your behalf by your FTP Client to the MSS FTP Service, as defined by the IETF standards and RFCs. These commands are either three or four characters long and will be shown in bold upper case characters, like this: ALLO. Commands you issue to your FTP Client will be shown in bold lower case characters, like this: put file. If, for some reason, you must have your FTP Client issue a command directly to the MSS FTP Service, you probably can use the FTP Client quote command. MSS FTP Service commands are not case sensitive, but any MSS related parameters such as UCAS account name, passwords, pathnames and comments are case sensitive.
