The sample library enables reading and writing text to and from the USB port, 
changing the baudrate, and changing the hardware flow control. 
The sample application displays a dialog window which emulates a serial terminal
using the sample library. In order to test the library, you can connect the 
bridge's USB port into your host computer's USB port, and the bridge's serial
port into your host computer's serial port, and then run both the sample 
application and a terminal program on your host (like Microsoft's HyperTerminal:
accessible through Start menu -> Programs -> Accessories -> Communications). 
The text written to the terminal should be received and displayed in the sample 
application and vice-versa.
