2.18.2 Share IRQ (PCM-9550F/9550FM only)

The IRQ and the address range for COM1, 2, 3, 4 default 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 below shows the settings for the PCM-9550F/FM’s serial

ports.

Windows NT.
