TSX (PDP11) started in the 70's.
TSX32 (80386+ platforms) started in the 80's.
I've been closely involved with it for over 25 years. I'd be tickled
pink to tell you more about it.

It would certainly be terrific if TSX (which can't do a secure-anything)
could, with the help of a Linux intermediary, end up doing a secure copy
(scp/ssh/sftp). But I don't yet see how.

Presumably, "A" is TSX running an ftp client and "B" is Linux running
the vsftpd server to which TSX connects. I don't see how you can wedge
the functionality of "have it (ie: machine B) transfer a file" inside
the vsftpd server.
