// Properties:
//	NO	Abstract class (does not have any objects)
//	NO	Is derived from Wnd
//	NO  Two stage creation (constructor & Initialize())
//	NO	Has a message map
//	NO	Needs a resource (template)

// Description :         
//	COXSerialCommConfig class
//		This object defines the port configuration settings like port ID, baudrate,
//		bytesize, parity, stopbits and flowcontrol. You can set also the size of
//		the software buffers and the timeout values of the ‘clear to send’,
//		‘data set ready’ and ‘Carrier detect’ signals. These settings can be loaded
//		and saved to disk.

// Remark:
//


// Prerequisites (necessary conditions):
//
