I remember zmodem over telnet. As with IND$FILE, it was all the same session.
BTW, while with TCAM you could attach ASCII tty and other s/s terminals via WP mode, with VTAM you needed NTO or some other protocol converter. -- Shmuel (Seymour J.)

I don't know what would have happened if I typed CALL IND$FILE. Remember XMODEM, YMODEM, KERMIT, ... Hayes Kermit spoofing ...? Maybe Kermit is the IND$FILE client.
