Onboard Serial Ports (1, 2)
Normally, the main board's I/O chips will occupy a certain portion
of memory space. For each I/O device the computer provides an
I/O address. The more devices attached the more address needed
to organize the memory storage areas. If all the I/O devices were
run through the same address, your devices would come to a near
halt. By providing the end user with four serial ports this allows
devices to run more efficiently if needed. Also the corresponding
interrupt needs to be selected.
Selections of logical COM port addresses are as follows. ( 3F8/
IRQ4, 3E8/IRQ4, 2F8/IRQ3, 2E8/IRQ3)
