Since you have loopback adapter connected you need to read/write from
the device at the same time.  So...  first attempt:
  cat </dev/ttyr00 > /dev/null &
  time cat large_file > /dev/ttyr00

Been a long time since I played with serial comms, but that'd be my first
attempt.

Second attempt would be to make a full serial connection to another machine
(port on the same machine?) and use "ckermit" to transfer a file.
