So you would expect to see this done explicitly in the source for an FTP client or server implementation -- something that sets this PSH flag or else the protocol won't work? Or am I misunderstanding what you mean? I don't see that specific string anywhere in a the particular FTP implementation whose source happened to be handy, basically a Berkeley 4.4 variant as I think most are on UNIX. Somewhere around here I have a pass-through FTP client/server application that adds GSSAPI-Kerberos5 authentication to the protocol traffic, and I don't remember needing to do any such thing there. I'd have to look harder at the details, but as I recall it, like any sane application the protocol is defined in terms of data, so you know if you have a complete command by looking at what you have.
