Please try a known working program until you are sure the hardware
is ok. With txd looped to rxd, when you "cu -l /dev/cua01" and type
something, it should be immediately displayed back.

If I try that here, it leaves the port in a state where if I try and
use cu afterwards, it will receive but not transmit.

See tty(4) ("man 4 tty").
