* default setting

The IRQ and the address ranges for COM1 and 2 are fixed.

However, if you wish to disable the port or change these parameters later

you can do this in the system BIOS setup. The table overleaf shows the

default settings for the panel PCís serial ports.

COM1 and COM2 are one set. You can exchange the address range and

interrupt IRQ of COM1 for the address range and interrupt IRQ of

COM2. After exchanging, COM1's address range is 2F8 ~ 2FF and its

request IRQ is IRQ3: and COM2's address range is 3F8 ~ 3FF and its

interrupt IRQ is IRQ4.
