ports, each time specifying the appropriate I/O port address
(i.e., 288, 290, 298, etc.) and the same IRQ (i.e., 10).
14. Now you must edit the registry database in order to inform
the serial driver that all the Echo serial ports will share the
same IRQ. There are two methods for doing this; a simple
Method A and a more complex, but more powerful Method
B.
