4. Explain: (1) Show how to write a function for input data.
   	        (2) To get a string.
            (3) To use C function: sscanf,or just use Scanf().
	    ** MSC 6.0 cannot use Scanf(), because don't support function vsscanf()	
5. Hordware: 7188/8000 

                                                                                                                                                 
6. Before the program call InstallCom1( ), it can use Kbhit( ), Getch( ), Putch( ),Print( ), Scanf( )... 
to send/receive data to/from COM1 of 7188x/8000.

7. But after call Installcom1( ) these functions will not work until the program call RestoreCom1( ).
  
All these I/O functions only apply to the main Command port (console port)
Command port list
