If you can get an ASR 33 to operate at 300 baud, you've accomplished
a miracle.  I suspect you were running at 110 baud, or 10 characters
per second.  And even at that rate, your TTY must be finely tuned to
handle CR-LF without an extra delay.  It can be that finely tuned.
Teletype field technicians from the home company did it routinely.
But if you're lazy with field service, it was common to add some
no-op characters like nulls or rubouts after each CR-LF to let the
carriage settle.
