That is exactly what happens. Frankly, I'm very dissapointed with the
Minstrel Springboard code. It was just a blind patch of serial io to the
Springboard not taking advantage of the functionality of the bus. So much
more could have been done if they memory mapped the io.

This is why there is a second serial port on the Visor Edge with RTS and CTS
lines and a different creator ID. The Visro Edge may work for you since it
has two real and seperate serial ports.
