Left-click on I/O Port in Resources. Tab to view currently used addresses.

Scroll through the list, check 03F8H, 02F8H, 03E8H, 02E8H. If one of these is available, use it. If not, check alternates.

Find a free address in the list. Most desktop PC’s have a COM1 and possibly a COM2 already on their system, which will be seen in the list. You may have to start at COM3 or COM4 to start your addressing of the ISA card you have. If these addresses are used you may have to resort to the Frequently Unused Port Addresses (found in Chapter 4, Table 3) of this manual. Write these open addresses and IRQ’s down for later reference.
