Control-T in TOPS-10 was done straight out of the monitor. If you were
on a slow 300 baud or 110 baud terminal on say a DZ11*, and kept hitting
Control-T really fast, you'd slow down everything else on the machine as
there was no buffering of serial TTY I/O and the monitor would sit and
wait for each character to be transmitted.
ak
* a DZ11 is UNIBUS and was only available on a KS10 - but I'd imagine
any straight serial port on a KA/KI/KL10 would do the same. If you were,
say, on a DCA mux, that had a 14.4K serial link straight into the
UNIBUS, there was much less of an effect.
