CPU can easily keep up at 9600 baud for a simple terminal that just
displays one character for each character received, and sends one
character for each key pressed.
But a "smart" terminal may have to do a lot of processing for a single
character received. There were ESC sequences to insert/delete lines,
insert/delete characters, erase to end of line, etc. These are the ones
that caused the CPU not to be able to keep up.
Anyone who has never made a mistake has never tried anything new.
