I was imagining the latter, recalling days of yore when I could connect
to TSO or CMS with a serial (VT52-like) terminal.  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$FILE client.  Rocket discusses both IND$FILE

I recall each terminal type had a dedicated range of ports on the 3705(?);
nothing like a TERMINFO data base.

I once tried disabling software ASCII<->EBCDIC translation and was astonished
that the bits came in backwards.
