** Purpose: In CSTerm application, SettingsWindow allows the user
**		  : to modify port settings: baudRate, portName, connection type, 
**		  : parity, encoding, dataBits, stopBits, and handshaking.
**		  : It is not guaranteed that ANY combination of settings
**		  : will be allowed by your serial driver.
