I remember loading paper tapes into a PDP-8, and the reader

the serial interface board to control the reader. It would
not be done with xon/xoff or CTS, as these were NOT RS-232
interfaces, but current loop. But, at least some people are
doing this with software-emulated PDP-8s, so that was sort
of what I was thinking of.

Indeed, unless you need character pacing.
Actually, with the correct settings of the serial port
(xon/xoff or CTS pin) the serial port driver should do
this, too, so cat would work.
